Vision Loss

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 August Wallace Eyecare Associates in Longview to book your comprehensive eye exam today!

8 Ways to Protect Your Eyes at the Office

Everyone seems to be staring at a screen these days, whether their computer, their smartphone or another digital device. The stress it puts on your eyes can cause a condition called “digital eye strain” (DES) or “computer vision syndrome” (CVS). Symptoms include eye fatigue, dry eyes, blurred vision, headaches, neck and shoulder pain, red eyes, and eye twitching.

How To Protect Your Eyes While You Work

Below are a few things you can do to lower your risk or mitigate any discomfort associated with DES.

1. See your eye doctor for a comprehensive eye exam

This is one of the most important things you can do to prevent or treat symptoms associated with computer vision syndrome. During your eye doctor’s appointment, make sure to speak with Dr. August Wallace about your working habits, including the frequency and length of time you use a computer and other devices at work and at home.

If you get a chance before you come, measure the distance between your eyes and your computer screen and bring that information to the optometrist, so that you can get your eyes tested for that specific working distance.

Computer vision syndrome may be exacerbated by an underlying dry eye disease, which can be diagnosed and treated at our eye clinic in Longview.

Sometimes people who have good visual acuity assume they don’t need any glasses. However, even very mild prescriptions can improve eyestrain and curb fatigue when working at a computer.

2. Good lighting is key

Excessively bright light, whether due to outdoor sunshine coming in through the window or harsh interior lighting, is a common cause of eyestrain. When using your computer, your ambient lighting should be about 50% dimmer than what is typically found in most offices.

You can reduce exterior light by closing drapes, blinds or shades and diminish interior illumination by using fewer or lower intensity bulbs. Computer users often find that turning off overhead fluorescent lights and replacing them with floor lamps is easier on their eyes.

3. Minimize glare

Eyestrain can be aggravated by glare from light reflecting off surfaces including your computer screen. Position your computer so that windows are neither directly in front of nor behind the monitor, but rather to the side of it. Consider installing an anti-glare screen on your display. If you wear glasses, get anti-reflective (AR) coating on your lenses to reduce glare by limiting the amount of light that reflects off the front and back surfaces of your lenses (more on that below.)

4. Upgrade your display

If you have a CRT (cathode) screen on your monitor, consider replacing it with a flat-panel LED (light-emitting diode) screen that includes an anti-reflective surface. Old-school CRT screens can be a major cause of computer eye strain due to the flickering images.

For your new flat panel desktop display, choose one with a diagonal screen size of at least 19 inches, and the higher the resolution, the better.

5. Adjust display settings for added comfort

Adjusting your computer display settings can help decrease eye strain and fatigue too.

  • Brightness: Adjust your device’s brightness to match the luminance around you. If the white background of this page looks like a light source, then it should be dimmed. However, if it appears dull and gray, it may not provide enough contrast, which can make it hard to read.
  • Text size: Adjust the text size for maximum eye comfort, particularly when reading, editing or writing long documents. Increase the size if you find yourself squinting, but bigger isn’t always better, since overly large text display may force your eyes to track back and forth too quickly for comfort.
  • Color temperature: This refers to the spectrum of visible light emitted by a color display. Blue light is short-wavelength visible light, whereas orange and red are longer wavelength hues. Exposure to blue light helps keep you alert but tends to cause eye fatigue after a while; yellow to red tints are more relaxing and may be better for long-term viewing, especially at night. Many devices allow the user to adjust the color temperature.

6. Get computer glasses

Nearly 70% of North Americans experience digital eye strain related to prolonged use of electronic devices. To combat these effects, August Wallace Eyecare Associates recommends digital protection coatings, which act as a shield to cut the glare and filter the blue light emanating from digital screens and artificial light.

For the greatest eye comfort, ask Dr. August Wallace for customized computer glasses, which feature mildly tinted lenses that filter out blue light. These can be made with or without prescription vision correction, for the benefit of those with 20/20 vision or contact lens wearers, though many people with contacts actually prefer to have alternative eyewear to use when their lenses become dry and uncomfortable from extended screen time.

August Wallace Eyecare Associates can help you choose from a vast array of effective optical lenses and lens coatings to relieve the effects of digital eye strain.

7. Don’t forget to blink

When staring at a digital device people tend to blink up to 66% less often, and often the blinks performed during computer work are only partial which aren’t as effective at keeping the eyes moist and fresh feeling. Making a conscious effort to blink more while working or watching can prevent dryness and irritation.

8. Exercise your eyes

Another cause of computer eye strain is focusing fatigue. Look away from your computer every 20 minutes and gaze at an object located 20 feet away, for a minimum of 20 seconds. This “20-20-20 rule” is a classic exercise to relax the eyes’ focusing muscles and reduce computer vision syndrome.

 

The steps above don’t require a tremendous amount of time or money to be effective. Contact August Wallace Eyecare Associates in Longview to make an appointment with Dr. August Wallace and learn how the right eye drops, eye exercises, computer glasses, or AR coatings can improve eye comfort, reduce computer vision syndrome and potentially lead to increased productivity and job satisfaction.

3 Ways Diabetes Can Affect Your Vision and Eyes

Did you know that people with diabetes are 20 times more likely to get eye diseases than those without it? There are three major eye conditions that diabetics are at risk for developing: cataracts, glaucoma, and diabetic retinopathy. To prevent these sight-threatening diseases, it’s important to control your blood sugar level and have your eyes checked at least once a year by an eye doctor.

But First, What Is Diabetes?

Diabetes is a disease that is associated with high blood glucose levels. Insulin, a hormone produced by the pancreas, helps our cells get energy from the sugars we eat. Diabetes develops when the body doesn’t produce or respond to insulin effectively, leaving too much sugar in the blood stream instead. Over time, diabetes can lead to potentially irreversible ocular damage and poor eyesight. However, by taking care of your blood sugar levels and your eyes, you can prevent vision loss.

Annual eye exams are recommended for everyone, but routine screenings are even more important for diabetics. Eye doctors may send diabetic eye health reports to a patient’s primary care physician or internist to adjust medication as needed to prevent complications.

What’s the Link Between Vision and Diabetes?

Blurred vision or fluctuating eyesight clarity is often one of the first noticeable signs that diabetes has begun to affect your eyes. Sometimes, fluid leaking into the eye causes the lens to swell and change shape. This, in turn, makes it difficult for the eyes to focus, resulting in fuzzy vision. Such symptoms can indicate that an eye disease is developing, or may simply be due to imbalanced blood sugar levels which can be rectified by getting your blood sugar back to healthy levels.

If you start to notice blurry vision, make an appointment with Dr. August Wallace as soon as possible.

The 3 Ways Diabetes Impacts Vision

Cataracts

While cataracts are extremely common and a part of the natural aging process, those with diabetes tend to develop cataracts earlier in life. Characterized by a clouding or fogging of the lens within the eye, cataracts impede light from entering the eye, causing blurred vision and glares. The best treatment is cataract surgery, which is very safe and effective.

Glaucoma

Glaucoma refers to a group of eye diseases characterized by optic nerve damage. Since it tends to impact peripheral vision first, glaucoma often goes unnoticed until significant damage has occurred. However, routine glaucoma screenings can detect warning signs; early treatment can prevent disease progression and vision loss.

Although there is no true cure for glaucoma, most glaucoma patients successfully manage it with special eye drops, medication, and on occasion, laser treatment or other surgery. The earlier glaucoma is diagnosed and managed, the better the outcome.

Diabetic Retinopathy

Diabetic retinopathy occurs when the small blood vessels on your retina (capillaries) become weakened and then balloon (microaneurysm) due to poorly controlled blood sugar levels. The resulting poor blood circulation in the back of the eye causes more abnormal blood vessels to grow, which also bleed or leak fluid, and can lead to scar tissue, retinal detachment and even blindness, over time.

Often there are no symptoms until the advanced stages of diabetic retinopathy, where patients may begin to see spots and missing patches in their vision. Retinopathy can be treated through surgery and eye injections, but the best way to prevent this disease from progressing is to regularly have your eyes screened.

The good news is that diabetic eye disease can often be prevented with early detection, proper management of your diabetes and regular diabetic eye exams. Contact August Wallace Eyecare Associates in Longview to set up your eye doctor’s appointment today.

Can Contact Lenses Give Me 20/20 Vision?

Before our eye doctor answers the question about whether or not contacts can help you achieve 20/20 vision, let’s discuss what those numbers mean. Everyone talks about 20/20 vision all the time, but what is it exactly? Our optometrist at your nearby eye care center in Longview can answer any questions you may have.

What’s the meaning of 20/20?

In general, “normal eyesight” is referred to as 20/20 vision. These numbers describe what you should see when standing 20 feet away from an eye chart. Accordingly, if you are diagnosed with 20/40 vision, it means that when you stand 20 feet away from the same eye chart, you can only see the details that a person with normal eyesight sees at 40 feet. That makes your vision weaker than average. In contrast, if you have 20/10 vision, it means that if you stand 20 feet away, you can see details that most people only see at 10 feet – which is better than the normal standards for vision.

How sharp will I be able to see with contact lenses?

At our Longview eye clinic, we aim to fit you with contact lenses that give 20/20 vision. Our experienced, skilled optometrist will check your visual acuity with the help of a basic Snellen testing chart and advanced diagnostics. We’ll figure out your precise vision prescription for contact lenses, giving you 20/20 vision or close to it. Our eye doctor is dedicated to making sure you enjoy the sharpest vision possible for your lifestyle needs!

Is it possible to see better than 20/20?

Yes, it is certainly possible. But the accepted gold standard is to correct human vision conditions with lens powers that bring your eyesight to the average norm of 20/20. On the other hand, if you are an eagle (and our eye doctor welcomes all eagles to visit us at August Wallace Eyecare Associates when flying through Longview), we can treat you with prescription contact lenses to restore the standard 20/5 vision that gives eagles a fine bird’s eye view of the world!)

Contact lenses vs. eyeglasses – do they give the same vision quality?

As far as vision quality goes, the primary advantage of contact lenses is that they offer more natural vision. Because they sit directly on your eye, they bend light in a way that’s closer to the requirements of your vision prescription. In addition:

  • Contacts also move along with your eyes, and no bulky frames block you from having clear peripheral vision – without needing to turn your head. (This is a big plus for people who play sports!)
  • Contact lenses don’t fog up when it’s cold outside or get wet when it’s rainy, so you have sharp vision in all weather conditions.
  • If you have astigmatism, our Longview eye doctor may recommend rigid gas permeable contact lenses, because they can give more acute vision than soft lenses and eyeglasses.

What’s better for me – contacts or glasses?

If your eyes are generally healthy, the choice between glasses and contact lenses is yours to make. Like everything, there are pros and cons to each type of vision correction. How should you make this decision? It mainly comes down to lifestyle and personal preferences. At our Longview eye care center, we’ll discuss your daily activities with you to help determine whether eyeglasses or contact lenses are most suitable.
