Spotlight on eye health: What is nystagmus?

According to the American Optometric Association, nystagmus is “a vision condition in which the eyes make repetitive, uncontrolled movements, often resulting in reduced vision.” Although many people inherit the condition and show signs within the first two or three months of life, other people acquire it later in childhood or adulthood after experiencing an accident. Nystagmus is characterized by involuntary eye movements, for instance glancing up and down or from side to side. People with nystagmus may attempt to see more clearly by nodding their head or holding their head in abnormal positions. Other effects of this condition include trouble with depth perception, which may lead to feeling unbalanced or uncoordinated.

The American Optometric Association suggests that when acquired later in life, nystagmus may be a symptom of a larger condition, such as a stroke or multiple sclerosis. Nystagmus is also associated with albinism, central nervous system diseases, and inflammation of the inner ear. If you suspect you may suffer from this condition, it is very important to see an optometrist on your True Dental Discounts, vision plan for a comprehensive eye exam. The optometrist will test your visual acuity and look at the way your eyes move and focus. He or she may also refer you to another medical specialist if it appears the nystagmus is a symptom of another underlying condition. In some cases, people with nystagmus can improve their vision with the help of prisms and special glasses, but there is no known cure for the condition. Fortunately, an optometrist can help you identify related conditions and work with you to make your vision as healthy as possible. Take the first step toward that goal today.

I don’t wear glasses. Do I need to visit the eye doctor?

Yes. According to a recent survey by the American Optometric Association, 20 percent of adults who do not wear glasses or contacts have never been to an eye doctor. Many of them assume that since they do not have noticeable problems with their vision, it is not necessary to schedule an appointment. Unfortunately, this common misperception often has devastating consequences, particularly when it comes to glaucoma. The American Optometric Association reminds patients that glaucoma – a degenerative vision condition – often “sneaks up” without any signs of pain or other symptoms.

Although this condition is not yet curable, it is treatable, and the earlier treatment begins, the better the patient’s future quality of life. For this reason, it is extremely important for all adults to visit an optometrist regularly. The American Optometric Association suggests adults under 60 without vision problems should schedule an eye exam once every two years. After age 60, an exam should be conducted annually. More frequent appointments may be necessary, depending on the person’s medical history and current health. If you have never been to the eye doctor, it’s easy to schedule that first appointment: Just call an optometrist on your True Dental Discounts vision plan. You will reap significant savings while also taking control of your health.

Protecting your eyes from the sun

When you’re out playing or working outdoors this summer, protection from the sun is of the utmost importance. In addition to applying sunscreen frequently, people need to also remember to protect their eyes from harmful radiation. According to the American Optometric Association, overexposure to UV rays can lead to cataracts, macular degeneration, or even skin cancer around the eyelids. Some people may also experience sunburn of the eyes, which is typically accompanied by blurred vision, redness, and temporary vision loss. In severe cases, sun damage to the eyes can result in blindness.

To prevent such damage, it is important to always wear protective sunglasses or contact lenses. The American Optometric Association strongly suggests that people wear protective lenses in all types of weather – even on cloudy or wintery days. Lenses should block 99 to 100 percent of UV-A and UV-B radiation and screen out 75 to 90 percent of visible light. People who are visually impaired often benefit from brown or amber-tinted lenses because they increase contrast while reducing light intensity. Gray-colored lenses are another excellent choice for filtering out harmful light rays.

Parents should remind their children and teenagers to protect their eyes from the sun, especially on days where they are outside for long stretches of time.
