Are You Susceptible To Vision Loss?

Vision loss is more common than you may think! In fact, it’s among the most prevalent disabilities in adults and children. Knowing what puts you at risk of developing vision loss is important and can help you to be proactive about caring for your eyes.

Below, we’ll explore the most common causes of vision loss and the risk factors associated with each.

Spreading awareness and education about visual health is just one way that our eye doctors near you can help. To schedule your comprehensive eye exam, call us today.

Common Causes of Vision Loss

Glaucoma

Glaucoma is a group of eye diseases caused by a buildup of pressure within the eye. Too much inner-eye pressure can damage the optic nerve and lead to vision loss.

Since symptoms don’t usually manifest in the early stages of glaucoma, getting regular eye exams is all the more crucial. Advanced or rapidly progressing glaucoma can show a variety of symptoms, such as blurred vision, headache, severe eye pain and redness, seeing halos around lights, and nausea.

Risk factors for developing glaucoma include:

  • Being 60 years or older
  • Family history of glaucoma
  • African, Asian, or Hispanic descent
  • High myopia (nearsightedness) or hyperopia (farsightedness)
  • Previous eye injury or certain eye surgeries
  • Certain medications, like corticosteroids
  • Thin corneas
  • Certain medical conditions, like diabetes, hypertension, heart disease, and sickle-cell anemia

Cataracts

Cataracts occur when the eye’s lens becomes cloudy. A healthy lens is clear and allows light to pass through it undisturbed.

Common cataract symptoms include cloudy or blurred vision, difficulty seeing at night, light sensitivity, double vision in the affected eye, and seeing colors as faded or yellowish.

Risk factors for developing cataracts include:

  • Aging
  • Diabetes
  • Hypertension
  • Smoking
  • Previous eye surgery, injury, or inflammation
  • Alcoholism
  • Extended use of corticosteroids

Age-Related Macular Degeneration (AMD)

AMD is the leading cause of severe vision loss in adults over the age of 60. It occurs when the macula (the small central portion of the retina, which is responsible for sharp, colorful, central vision) begins to wear down.

Early stages of AMD usually go unnoticed, but later stages of the disease can produce symptoms like blurred vision, dark or blurry areas in your central vision, and problems with color perception.

There’s not yet a cure for AMD, but certain treatments can help prevent vision loss.

Risk factors for developing AMD include:

  • Smoking
  • Obesity
  • Aging
  • Long-term sun exposure
  • Hypertension
  • Heart disease
  • Family history of AMD
  • Light-colored eyes
  • Farsightedness

Diabetic Retinopathy (DR)

Diabetic retinopathy is a complication of Type 1 or Type 2 diabetes that affects the light-sensitive tissue at the back of the eye called the retina.

Initially, diabetic retinopathy shows no symptoms but can eventually lead to blindness. As it develops, it can cause increased floaters, impaired color vision, dark spots in your visual field, and blurred vision.

Risk factors for developing diabetic retinopathy include:

  • Length of time from diabetes diagnosis — the longer you’ve had it, the higher your chances of developing visual complications
  • Uncontrolled blood sugar
  • Obesity
  • High cholesterol or blood pressure
  • Pregnancy
  • Smoking
  • African American, Hispanic, and Native American ethnicities
  • Family history of DR

So, what’s the bottom line ?

Multiple factors contribute to eye disease and vision loss, and some may even be relevant to you. If you think you may be at risk for vision loss or experience any of the symptoms listed above, speak with your eye doctor in Greensboro as soon as possible. We also recommend you have your eyes thoroughly examined every 1-2 years, or as often as your eye doctor recommends. To schedule your comprehensive eye exam, call Miller Vision Specialties today.

 

Frequently Asked Questions With Our Greensboro Eye Doctors

  1. Can blindness be prevented?

When caught early, many eye diseases can be treated to halt or slow the progression of the disease and potentially prevent vision loss. The best things you can do to preserve your vision for the long term is to lead a healthy lifestyle and make sure you undergo a comprehensive eye exam every 1-2 years.

  1. Which eye diseases are genetically inherited?

More than 350 ocular diseases have some sort of genetic component. Certain diseases, like retinitis pigmentosa and albinism, are directly inherited through chromosomal information. In other cases, a predisposition to the disease is inherited, rather than the disease itself.

How Sleep Apnea Affects The Eyes

Did you know that some eye conditions are associated with sleep apnea? According to the National Sleep Foundation, more than 18 million Americans have sleep apnea, and Health Canada reports similar prevalence. It’s a sleep disorder where people stop breathing — often multiple times per night — while sleeping.

If you have sleep apnea: it tends to take longer for your tears to be replenished, you’re more likely to have ocular irritation, you have a higher chance of developing floppy eyelids, and you’re at increased risk for glaucoma.

What Is Obstructive Sleep Apnea?

There are different types of sleep apnea. The most common one is obstructive sleep apnea (OSA). During OSA, your airway becomes partially blocked due to relaxed muscles in your nose and throat. This causes apnea (the absence of breathing) or hypopnea (abnormally shallow, slow breathing). It’s twice as common in men, and is more likely to affect people with obesity, hypertension, diabetes or heart disease.

What are the common symptoms of sleep apnea?

Sleep apnea occurs when the muscles in the back of your throat relax too much to allow normal breathing. These temporary breathing lapses cause lower-quality sleep and affect the body’s oxygen supply, which can lead to potentially serious health consequences.

While snoring is a common symptom, not everyone who snores has sleep apnea. Interrupted sleep can cause excessive daytime sleepiness, fatigue, irritability or depression, headaches in the morning, difficulty concentrating and thinking, and a sore throat.

Which Eye Conditions Are Associated With Sleep Apnea?

Glaucoma

Glaucoma occurs when increased pressure within the eye damages the optic nerve, which connects the eye to the brain, leading to vision loss and sometimes blindness. In some cases, it might be due to a drop in blood oxygen levels, which happens when you stop breathing. However, CPAP machines, one of the most common treatments for sleep apnea, can also cause glaucoma.

So, people with sleep apnea — even if it’s being treated — need to get their eyes checked on a regular basis for glaucoma.

Floppy Eyelid Syndrome

Floppy Eyelid Syndrome (FES) is an eye condition where a person has an unusually large and floppy upper eyelid. It can cause eye redness, irritation, discharge, or blurry vision — and over 90% of people with FES also have sleep apnea.

Non-Arteritic Anterior Ischemic Optic Neuropathy

Non-arteritic anterior ischemic optic neuropathy (NAION) is an eye condition that occurs when there is a loss of blood flow to the optic nerve. Patients typically complain of significant vision loss in one eye without any major pain. Approximately 70-80% of patients with NAION have been found to have OSA.

Retinal Vein Occlusion

Also referred to as an ‘eye stroke,’ retinal vein occlusion (RVO) is a blockage of the small veins that carry blood away from the retina. A recent study of 114 RVO patients found that sleep apnea was suspected in 74% of the patients that had previously been diagnosed with RVO.

Other Eye Health Issues Associated With Sleep Apnea

Some other ocular conditions that are more common in patients with sleep apnea include: papilledema, keratoconus, and central serous chorioretinopathy. Furthermore, in addition to glaucoma mentioned above, CPAP machines are associated with dry eye syndrome and bacterial conjunctivitis.

Talk To Your Doc

Get eye exams regularly to rule out eye disorders and prevent potential vision loss, especially if you have been diagnosed with sleep apnea. At Miller Vision Specialties in Greensboro we encourage you to share your medical history with us so we can better diagnose and treat any eye conditions or ocular diseases you may have, and help you keep your eyes nice and healthy.

Frequently Asked Questions with Dr. Sally Miller

Q: What Causes Sleep Apnea?

  • A: Sleep apnea occurs when in-part or completely stop breathing when sleeping. This causes your lungs to strain harder for oxygen, and makes the brain send signals that jerk your body awake to resume proper breathing.

Q: What are the Warning Signs of Sleep Apnea?

  • A: A common sign of sleep apnea is loud snoring. Snoring that is loud enough to disturb the sleep of the patient as well as others around, even across the walls. That said, not everyone who snores suffers from obstructive sleep apnea.

3 Benefits of Anti-Glare Coating

Glare refers to the excessive brightness caused by direct or reflected light. It can cause eye strain, digital eye strain (when using a computer, for example), halos, and headaches. Glare can also reduce visibility, making it unsafe to drive.

Anti-glare coating, also known as anti-reflective (AR) coating, is a thin layer applied to the surface of your eyeglass lenses that allows more light to pass through your lenses. By reducing the amount of glare that reflects off of your lenses, you can see more clearly and experience more comfortable vision. You can request anti-glare coating for lenses when you buy eyeglasses.

AR Coating Offers 3 Major Advantages

Better Appearance

Without an anti-glare coating on your glasses, camera flashes and bright lights can reflect off your lenses. This can hinder your appearance when speaking to people or in meetings, cause flash reflections when picture-taking, and make it difficult to find the right angle for video calls. Anti-reflective coating eliminates the harsh reflections and allows others to clearly see your eyes and face.

Reduced Digital Eye Strain

You know that tired, irritated feeling you get after staring at a digital screen for several hours? That’s digital eye strain. Anti-glare coating helps reduce digital eye strain by lowering exposure to excessive glare from digital devices and lighting.

Safe Driving at Night

The bright headlights from cars driving in the opposite direction can pose a serious danger when driving at night. These sudden glares can lead you to momentarily lose focus of the view ahead. AR coating on your prescription eyewear effectively reduces reflections from headlights at night, allowing you to enjoy a better view of the road and safer driving at night.

Let your eyes look and feel better every day with anti-glare coated lenses. Contact us to book your appointment today!

Frequently Asked Questions with Dr. Sally Miller

Q: Can you request lenses made from glass? Is glass still used for lenses?

  • A: Yes. Opticians still sometimes use glass for lenses. However, glass is not used very often because they aren’t as safe. If these glass lenses breaks, they can shatters into many pieces and can injure the eye. Glass lenses are much heavier than plastic lenses, so they can make your eyeglasses less comfortable to wear.

Q: Can a coating be added to eyeglasses to protect them from further scratches?

  • A: A protective coating can’t be added to a lens after it’s scratched. The coating is applied when the lens is manufactured and can’t be put on later.

How To Prevent Your Lenses From Scratching

If you wear glasses, then you know what a nuisance a scratched lens can be. Scratched or chipped lenses can interfere with your vision, making glasses uncomfortable to wear. Here’s what we recommend to keep your lenses scratch-free.

How to Avoid Scratching Your Lenses

Use a Protective Case

Using a sturdy eyeglass case will prolong the life of your lenses. No matter what kind of glasses you wear — standard, sunglasses, bifocal — you’ll want to protect them.

Be sure to choose a hard case with a soft inner lining and always have one on hand, either in your purse, backpack, or car.

When placing the glasses in their case, make sure the lenses are facing downwards, as this can reduce the risk of them being scratched. Additionally, avoid putting anything else in the case along with the glasses, especially sharp or metal objects.

Choose Anti-Scratch Lenses

Although no lenses are completely scratch-proof, there are certain coatings that can be added to the front and back of your lenses to make them more scratch resistant. Many lenses already come with this option, but sometimes it’s an optional addition. Anti-scratch coatings are particularly helpful for children’s glasses.

Remove Your Glasses Carefully

Handle your glasses by the temples (arms) and not the rims. This way, your fingers avoid the frame and lens area altogether, reducing the chance of inadvertently scratching them. Additionally, holding them by the temples with both hands ensures a better grip, so you’ll be less likely to drop them.

Set Them Down Properly

Never put glasses down with the lenses facing downward, unless it’s into a lens case. If you need to put them down and don’t have a case, rest them with the temples open and upside down — glasses tend to be more stable in this position.

Avoid placing them in a place where they’ll be easily knocked over or splashed on, like near a sink. Setting them down in the same place consistently will also reduce your risk of losing them.

Use the Right Lens Cleaner

It’s all too common for people to wipe their glasses with their clothing or other abrasive material. Doing so can scratch the lenses, especially if they’re dry.

Always clean your lenses with a soft microfiber cloth and specialized lens cleaning solution, items your optometrist’s office can provide.

When to Visit Your Optometrist

Unfortunately, it’s impossible to completely prevent your lenses from ever becoming scratched over their lifetime. Once they are scratched, there is little that can be done to repair the lenses. Most of the time the lenses need to be replaced.

At Miller Vision Specialties, we offer a wide array of frames and lenses, so you’re sure to find a pair to suit your eyes and needs.

Call Miller Vision Specialties in to schedule your eye exam or with any further questions.

What You Should Know About Night Blindness

If you don’t see well while driving at night, there’s a chance you have night blindness. Night blindness, or nyctalopia, is the inability to see well at night or in dim lighting. It’s not considered an eye disease, but rather a symptom of an underlying problem.

Our eye doctor in Greensboro can help diagnose, manage and treat your night blindness with specialized digital eye exams, so that you can enjoy being out and about at night again.

Here are 4 things you should know about night blindness:

Causes of Night Blindness

The inability to see well at night can be the result of a condition such as:

  • Vitamin A Deficiency — Vitamin A helps keep your cornea, the layer at the front of your eye, clear; it’s also an important component of rhodopsin, a protein that enables you to see in low light conditions. Although uncommon in North America, deficiency of this vitamin can induce night blindness.
  • CataractsA buildup of protein clouds the eye’s lens, leading to impaired vision, especially at night and in poor lighting conditions.
  • Diabetic RetinopathyDamage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.
  • GlaucomaThis group of eye diseases is associated with pressure build-up in the eye that damages the optic nerve. Both glaucoma and the medications used to treat it can cause night blindness.
  • MyopiaAlso called nearsightedness, myopia makes distant objects appear blurry, and patients with it describe a starburst effect around lights at night.
  • KeratoconusAn irregularly shaped cornea causes blurred vision and may involve sensitivity to light and glare which tend to be worse at night.
  • Retinitis Pigmentosa (RP)A progressive genetic eye disease which can be associated with other diseases, RP leads to night blindness and peripheral vision loss.
  • Usher SyndromeThis genetic condition causes both hearing loss and vision loss, including night blindness and RP, mentioned above.

Symptoms of Nyctalopia

Since night blindness is a symptom of some serious vision problems, it’s important to get your eyes checked regularly to ensure that everything is in good working order. Contact your eye doctor as soon as possible if you notice that you don’t see as well in dim light as you used to, such as when driving at night or when adjusting from being outdoors in the sunshine to being indoors.

Symptoms of Night Blindness Include:

  • Reduced contrast sensitivity
  • Difficulty seeing people outdoors at night
  • Difficulty seeing in places with dim lighting, like a movie theater
  • Trouble adapting to the dark while driving
  • Excessive squinting at night
  • Trouble adjusting from bright areas to darker ones

Treatments for Night Blindness

Your eye doctor will want to diagnose the cause of your night blindness in order to treat it. For example, in the rare case of vitamin A deficiency, it can be treated with vitamin supplements and vitamin-A rich foods; myopia can be corrected with eyeglasses or contact lenses. Other conditions may require medications or surgery.

If night blindness is caused by a birth defect, Usher syndrome, or retinitis pigmentosa, low vision aids and devices can help you make the most of your remaining vision.

Prevention

While there is no proven way to prevent night blindness resulting from genetic conditions or birth defects, consuming healthy, nourishing foods and taking certain vitamin supplements may prevent or slow the onset of some eye conditions that cause night blindness.

If you experience poor vision at night or in dim lighting, we can help. Contact Miller Vision Specialties in Greensboro to schedule your appointment today.

Are Contact Lenses Safe For Young Children?

Here’s a question we often get at our practice: ‘Is my child too young for contact lenses?’ This is an important question, and the answer may surprise you.

For children with myopia (nearsightedness), contact lenses can be a convenient method of vision correction. It allows kids to go about their day without having to worry about breaking or misplacing their glasses, and enables them to freely participate in sports and other physical activities.

Some children and young teens may ask their parents for contact lenses because they feel self-conscious wearing glasses. Contact lenses may even provide children with the confidence boost they need to come out of their shell. Moreover, these days, it is very popular for children to wear single-use one-day disposable soft contacts, since there is no cleaning or maintenance involved.

Some parents may deny their child’s request for contacts due to concerns about eye health and safety. There’s no reason to worry: contact lenses are just as safe for children as they are for anyone else.

At Miller Vision Specialties, we provide children, teens, and patients of all ages with a wide variety of contact lenses. If you’re concerned about the safety of contacts for your child, we’ll be happy to explain and explore ways to ensure maximum safety, optimal eye health and comfort. To learn more or to schedule a pediatric eye exam for contact lenses, contact us today.

What Are the Risks of Having My Child Wear Contact Lenses?

A study published in the January 2021 issue of The Journal of Ophthalmic & Physiological Optics found that kids aren’t at a higher risk of experiencing contact lens complications.

The study followed nearly 1000 children aged 8-16 over the course of 1.5-3 years to determine how contact lenses affected their eye health.

The results indicate that age doesn’t have an effect on contact lens safety. In fact, the researchers found that the risk of developing infections or other adverse reactions was less than 1% per year of wear — which is comparable to contact lens wearers of other ages.

But before you decide that contact lenses are right for your child, you may want to consider whether your child is ready to wear them. During his or her eye doctor’s appointment, the optometrist may ask about your child’s level of maturity, responsibility, and personal hygiene. Since many children are highly motivated to wear contacts, they tend to display real maturity in caring for their lenses. That said, in the initial stages, parents may need to play an active role, as their child gets used to inserting and removing the new contact lenses.

It’s important to note that just as with any other medical device, contact lenses are not risk-free. Anyone who wears contact lenses has a chance of developing eye infections or other complications with contact lenses. However, when worn and cared for according to your eye doctor’s instructions, contact lenses are low-risk and perfectly safe for children and teenagers.

So, go ahead and bring your child in for a contact lens consultation! We’ll help determine if your child is ready for contacts and answer any questions you or your child may have. To schedule your child’s contact lens fitting or eye exam, contact Miller Vision Specialties in Greensboro today.

6 Common Myths About Glaucoma

Glaucoma is an eye disease in which increased pressure causes progressive, permanent vision loss and even blindness. Unfortunately, many misconceptions about the disease can leave you misinformed. Below we sort fact from fiction by debunking 6 of the most common glaucoma myths.

Glaucoma Facts vs. Myths

MYTH 1: Glaucoma is a single disease

FACT

Glaucoma is a group of eye diseases; the most common ones are open-angle glaucoma (OAG) and angle-closure glaucoma (ACG).

In open-angle glaucoma, the drainage structure in your eye (called the trabecular meshwork) doesn’t allow the fluid inside the eye to flow out as it should, causing an increase in internal ocular pressure that damages the optic nerve. OAG develops slowly, and usually by the time people perceive symptoms, such as peripheral vision loss, they already have optic nerve damage.

In angle-closure glaucoma, the eye doesn’t drain fluid as it should because the drainage channel between your iris and cornea becomes too narrow, causing increased eye pressure. This pressure damages the optic nerve, leading to vision loss. ACG can occur suddenly or gradually.

MYTH 2: Only the elderly suffer from glaucoma

FACT

Although it’s true that people over 60 are at a greater risk of developing open-angle glaucoma compared to people in their 40s, there are other types of glaucoma that can affect people aged 20 to 50 and even young infants (due to abnormal ocular development).

In addition to age, those with a higher risk of developing glaucoma include:

  • African Americans and Hispanics
  • Individuals with a family history of glaucoma
  • Patients with cardiovascular disease, diabetes, or sickle cell anemia
  • Those who have previously sustained an eye injury
  • People taking steroid medications over the long term

MYTH 3: Glaucoma shows symptoms early on

FACT

The most common form of glaucoma, open-angle glaucoma, shows virtually no signs or symptoms until its later stages when vision loss sets in. Despite what people may think, the increased eye pressure causes no pain. And since peripheral vision is the first to go, you may not recognize vision loss until your vision has become significantly impaired. The only way to detect glaucoma is to undergo a comprehensive eye exam.

MYTH 4: Nothing can be done once you have glaucoma

FACT

While there’s currently no cure for glaucoma, many effective treatment options exist: eye drops, oral medications, as well as laser and surgical procedures that can help slow glaucoma progression. Each treatment option is used to get the fluid to flow properly out of the eye, reducing pressure inside the eye and decreasing damage to the optic nerve.

MYTH 5: Testing for glaucoma is painful

FACT

Actually, testing for glaucoma is practically painless. One of the tests includes a non-contact device that blows a gentle puff of air into each eye to test the intraocular pressure. The sound of the puff may be startling, but it’s over in a second and is painless. With the Goldmann applanation tonometry test, an anesthetic eye drop is inserted into each eye, which may cause a stinging sensation for a few seconds. Your eye doctor will then use a blue light to quickly and gently touch the cornea to precisely measure intraocular pressure. The most accurate of all, however, are visual field testing and OCT (optical coherence tomography), non-invasive imaging, both of which are also painless.

MYTH 6: You can’t prevent glaucoma

FACT

Regular eye exams are the only way to prevent glaucoma, as blindness or significant vision loss can be prevented if the disease is diagnosed and treated in the early stages. That’s why routine comprehensive eye exams which include glaucoma testing are so important.

Getting your eyes checked regularly can ensure that any existing eye problems are detected early enough to prevent or slow ocular damage. Contact Miller Vision Specialties in Greensboro to book your comprehensive eye exam today!

Frequently Asked Questions with Dr. Sally Miller

Q: If one of my parents has glaucoma, does that mean I will develop it as well at some point?

  • A: Having a parent with glaucoma does not mean that the child will automatically develop the condition too. However, those people with an immediate family history (parents, siblings) of glaucoma are at more risk to develop this disease. Patients should have a comprehensive eye examination each year to evaluate the health of the eyes and to look for signs of glaucoma. Some of these signs can be an increase in the pressure of the eyes as well as changes to the appearance of the optic nerve. Many times there are no symptoms noticed by the patient. If there is suspicion of glaucoma, more frequent visits to the eye doctor along with additional nerve testing are often required.

Q: Why do I need to scan my retinas/back of the eye?

  • A: The retina shows us a lot about the overall ocular health as well as systemic conditions that can affect the eyes. Often diabetes, hypertension or high cholesterol can be observed from a retinal scan. Also, retinal scans allow us to diagnose and treat macular degeneration and glaucoma. Scans are often very important for a complete eye check up.

Why Do Onions Make Us Cry?

Onions are one of the most common staple foods around the globe. Ironically, for a vegetable so delicious, they can often be tear-jerkers.

Read on to learn why onions cause your eyes to tear and sting, and what you can do to minimize discomfort.

Why Does Cutting Onions Cause Tearing?

Onions produce a sulfur compound called propyl sulfoxide that is stored in the cells of the onion bulb (the part of the onion we eat). Onions grow underground, where they can be eaten by all types of creatures. This odorous sulfuric compound acts as a deterrent to small animals with big appetites.

When one slices into an onion and breaks open its cells, the sulfur compound is released and mixes with the moisture in the air — turning it into smelly and irritating sulfuric acid. When this chemical rises up and comes in contact with your eyes, it stings!

To keep your eyes from potentially being damaged from this chemical exposure, your brain triggers your eyes to tear and flush out the irritating gas particles. Once enough tears have flushed out the sulfuric acids particles from the eye, clear vision and comfort is usually restored. Although your eyes may sting and feel unpleasant, symptoms are temporary and the sulfuric acid won’t damage your eyes.

How Can I Reduce Eye Discomfort When Chopping Onions?

Most experienced chefs will tell you that chilling your onions in the fridge for at least 30 minutes before slicing them will reduce the amount of tearing they cause. Propyl sulfoxide escapes slower in cooler temperatures, reducing the amount of sulfuric acid in the air.

You can also try cutting the onions at arm’s length, or direct the odorous air away with a small fan. Some say that chopping onions immersed in water also helps. Another option is to wear kitchen goggles to protect your eyes.

Furthermore, try to use fresh onions whenever possible. The longer an onion has been stored, the more likely it will induce tearing and discomfort. Try to avoid slicing near the root end of the bulb, as that area has the highest concentration of sulfuric compounds.

Still Having Eye Problems Out of the Kitchen?

If you frequently suffer from eye irritation — and not just while cutting onions — we can help. At Miller Vision Specialties, we treat a wide range of eye conditions and can provide you with the treatment and relief you seek.

Frequently Asked Questions with Dr. Steven Miller

Q: What exactly is glaucoma?

  • A: Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.

Q: What’s the difference between vision insurance and eye insurance?

  • A: Vision insurance” really isn’t insurance, but rather a benefit that covers some of your costs for eyewear and eye care. It is meant to be used for “routine” care when you aren’t having a problem but want to be sure everything is OK, like having an annual screening exam with your Primary Care Physician. It often, but not always, includes a discount or allowance toward glasses or contact lenses. It is usually a supplemental policy to your medical health insurance. Medical health insurance covers, and must be used when an eye health issue exists. This includes pink eye, eye allergies, glaucoma, floaters, cataracts, diabetes, headaches, and many other conditions. Blurry vision is covered medically if it relates to a medical condition, for example the development of a cataract. For some reason, however, it is considered non-medical if the only finding is the need for glasses or a change of prescription. Of course you can’t know this until you have the exam. In this case, with vision coverage, you would only be responsible for your co-pay, but with medical coverage without vision coverage, you’d be responsible for the usual charge.

Q: How does high blood pressure affect vision?

  • A: If the blood pressure is very high it can be called malignant hypertension and cause swelling of the macula and acute loss of vision. Otherwise hypertension can cause progressive constriction of the arterioles in the eye and other findings. Usually high blood pressure alone will not affect vision much, however hypertension is a known risk factor in the onset and/or progression of other eye disease such as glaucoma, diabetic retinopathy, and macular degeneration as well as blocked veins and arteries in the retina or nerve of the eye that can severely affect vision.

15 Things You Do That Can Harm Your Eyes

Eye health isn’t just about going for that yearly eye exam. Certain actions you take (or don’t take) in your daily routine can also have drastic effects on the health of your eyes and vision. Here’s our list of 15 things you may be doing that could pose damaging risks to your eyes.

It’s important to note that before changing any of your habits, consult with a medical professional to make sure they are right for you and your overall health.

1. Smoking

We all know that smoking can cause heart disease and cancer, but its effects on the eyes are far less known to many. The truth is that smoking can actually lead to irreversible vision loss by significantly increasing the risk of developing macular degeneration, cataracts, glaucoma, and diabetic retinopathy. It can also cause dry eye syndrome. If you are a smoker, do your eyes (and body) a favor and try to kick or reduce the habit.

2. Not Wearing Sunglasses

Exposing your eyes to the sun’s harmful UV radiation can damage the eye’s cornea and lens. Overexposure to UV rays can also lead to cataracts and even eye cancer. That’s why it’s important to always wear 100% UV-blocking sunglasses while outdoors, all four seasons of the year. Always check the sunglasses have FDA approval.

3. Sleeping with Makeup On

When you sleep with eyeliner or mascara, you run the risk of the makeup entering the eye and irritating the cornea. Sleeping with mascara on can introduce harmful bacteria to the eye and cause an infection. Abrasive glitters and shimmery eyeshadow can scratch the cornea as well. Be careful to remove all makeup with an eye-safe makeup remover before going to bed.

4. Buying Decorative Contact Lenses Without a Prescription

Although ordering decorative lenses without first visiting your optometrist may sound more convenient, purchasing them without a prescription isn’t worth the long term risks. Decorative contact lenses are sometimes made by unlicensed manufacturers who tend to use poor-quality or toxic materials that can get absorbed through the eyes into the bloodstream. They also may contain high levels of microorganisms from unsanitary packaging and storage conditions.

5. Not Washing Your Hands Thoroughly

Frequently washing your hands helps to reduce the possibility of bacteria and viruses entering the eye. Pink eye (conjunctivitis) and corneal ulcers are common eye conditions that can be caused by bacteria, viruses, fungi, or parasites. When washing your hands, be sure to use warm water, soap, and thoroughly wash in between each finger and over the entire palm area. If you plan to insert or remove your contact lenses, wash and then dry your hands completely with a lint-free cloth or paper towel.

6. Overwearing Contact Lenses

Wearing contact lenses for longer periods of time than intended can lead to inflammation of the cornea (keratitis), conjunctivitis, eyelid swelling, and contact lens intolerance. Always follow the recommended wear time as instructed by your optometrist.

7. Being Nutrient Deficient

Poor nutrition can cause permanent damage to the visual system. Try to include lots of nutrient-rich fruits and vegetables in your diet, along with adequate amounts of Omega-3. Some of the best vitamins and nutrients for eye health include Vitamins A, C, E, lutein, zeaxanthin, and zinc.

8. Using Non-FDA Approved Products

Whether it’s eyebrow enhancers, eye makeup, or eyelash growth serums, always choose products that have been FDA approved and/or meet government safety regulations. Non-approved products have been known to cause infections or allergic reactions in or around the eye area.

9. Not Cleaning Your Contacts Properly

If you are wearing contact lenses that need to be replaced once every two weeks or once a month, maintaining the highest level of contact lens hygiene is essential. Optometrists will tell you that a common reason patients come in to see them is due to an eye infection from contact lenses that haven’t been properly cleaned or stored. Some patients use their contact lens cases for too long, which can also cause eye irritation. To avoid eye infections, carefully follow your eye doctor’s instructions on how to clean, store, and handle your contact lenses.

10. Showering or Swimming with Contact Lenses

There is a significant amount of bacteria that can be carried in tap water and swimming pools. For this reason, it’s important to make sure that water and contact lenses don’t mix. If you need vision correction while swimming, it may be worth investing in a pair of prescription swimming goggles.

11. Not Following Medication Instructions

When it comes to eye disease, following the medication instructions is crucial. Forgetting to insert eye drops, or administering the incorrect dosage could dramatically reduce the effectiveness of treatment, or even do harm. Speak with your eye doctor if you’re not sure about when or how to take your medication.

12. Not Taking a Holistic Approach

Your eyes are just one part of the whole system — your body. Ignoring health conditions you may have, like high blood pressure or elevated blood sugar, can pose serious risks to your eyes.

13. Not Wearing Protective Eyewear

Shielding your eyes with protective glasses or goggles while working with potentially sharp or fast-moving objects, fragments or particles (wood working, cutting glass, welding, doing repairs with nails, certain sports) is the best defense against eye injury. In fact, 90% of all eye injuries could have been prevented by wearing protective eyewear.

14. Using Unsafe Home Remedies

Some might think that because something is “natural” that it is safe for use around the delicate eye area. Home remedies, like using breastmilk to cure pink eye, could introduce harmful bacteria to the eye and cause infection. If your eyes are giving you trouble, make an appointment to see your local optometrist.

15. Skipping Your Recommended Eye Exam

Your eye doctor will advise you how often you need to come for an eye examination. Adults should visit their eye doctor at least every year for a comprehensive eye exam to determine whether their optical prescription is up-to-date, and to check for the beginning stages of eye disease. Catching eye diseases in their early stages offers the best chance of successful treatment and preserving healthy vision for life.

The Importance of Eye Exams for Contact Lenses

Are you planning on wearing contact lenses for the first time? Do you need a new contact lens prescription? Are your current contacts not as comfortable as you wish they were? Your eye doctor will perform a contact lens eye exam to ensure that your vision with contacts is clear, comfortable, and safe, providing you with the right lenses for you.

What is a contact lens exam?

If you wear or want to wear contact lenses, you’ll need an eye exam for contact lenses, in addition to your regular comprehensive eye exam. Special tests are performed during a contact lens exam to evaluate your eyes and vision with contacts.

Are eyeglass prescriptions the same as contact lens prescriptions?

No, a prescription for glasses cannot be used for contact lenses. An eyeglass prescription is for lenses that are positioned approximately 12 millimeters from your eyes, whereas a contact lens prescription is measured for lenses that sit directly on the surface of your eye.

The prescription for contact lenses also includes the brand, lens diameter and curvature, which are not part of an eyeglass prescription.

Contact lenses fitting: One size does not fit all

One contact lens size doesn’t fit all eyes. If a contact lens is too flat or too steep for your corneal shape, you may experience discomfort or even eye damage. Your eye doctor will take certain measurements to determine the best contact lens design and fit for your eyes.

Corneal curvature

This measures the curvature of your eye’s clear front surface (cornea) so the eye doctor can select the optimal curve and diameter for your contact lenses. If your eye’s surface is somewhat irregular because of astigmatism or other conditions, you may require a special lens.

Pupil and iris size

The size of your pupil and iris (the colored part of your eye) is also important in determining the best contact lens design.

Tear film evaluation

This test evaluates the quality of your tears, to determine whether they will be able to keep contact lenses and your cornea sufficiently hydrated throughout the day. If you have dry eye disease, standard contact lenses may not be right for you.

Trial lenses

Following the eye exam, you will be provided with trial lenses to verify that the chosen contact lenses offer clear and comfortable vision. This will allow the eye doctor to make any fine adjustments to the prescription.

Contact Lens Eye Exam Near You

Wearing the correct contact lenses for your eyes allows you to enjoy all of the benefits of wearing contacts, while keeping your eyes healthy and comfortable.

If you’re already a contact lens wearer, visit your eye doctor at least once a year to make sure the lenses are still providing you with optimum vision and comfort.
