Eyesight is one of the most important and prized of all our special senses. Trouble with eyesight can lead to a tremendous reduction in quality of life. Imagine not being able to see well enough to drive, watch TV, read or see the facial expressions of loved ones and friends. Most people fear loss of vision over almost any other disability. Fortunately, with the advances in modern medicine we can now advise patients regarding the steps they can take to improve their chances of maintaining good vision throughout life.
“It is a good idea to remember that, in general, if something is good for your heart, it is good for your eyes,” states Dr. Todd Scott of The Eye & Laser Center.
Nutrition is important for optimal eye health. A diet rich in fruits and vegetables and good fats, like fish oil, have been shown in studies to reduce the risk of developing, as well as slowing the progression of, macular degeneration, which is the leading cause of permanent vision loss in retirement-age people. Smoking and high blood pressure, on the other hand, have been shown to increase the risk of vision loss from macular degeneration.
The leading cause of permanent vision loss in working-age people is diabetes. Maintaining a healthy weight, normal blood sugar and blood pressure, and not smoking can decrease the risk of loss of vision from diabetes tremendously. In general, diabetic patients should strive to keep their blood sugar in the normal range, which is 80 – 120, their blood pressure in the 110-120 over 70’s range, their LDL (bad) cholesterol under 100 and their HDL (good) cholesterol over 50. Of course, each patient is different and should follow the recommendation of his/her personal physician.
“The vast majority of people suffer vision loss from diabetes needlessly,” points out Dr. Kevin Nusz. “Severe vision loss can usually be prevented with proper treatment, but nearly 40% of diabetics in South Carolina have not had an eye exam since being diagnosed with diabetes. It is important that even newly diagnosed diabetics have yearly eye exams.”
Regular exercise is important to maintaining a healthy body weight. Excess body fat is associated with an increased risk of diabetes, high blood pressure and cholesterol, stroke, heart attack, memory loss and increased chronic inflammation which speeds up the aging process and is associated with macular degeneration. A good rule of thumb is to walk 30 minutes a day, six days a week.
“Regular exercise has also been found to lower the eye pressure and reduce the risk of glaucoma, a potentially blinding disease associated with high pressure in the eye,” adds Dr. Malcolm Edwards.
Cataracts (the clouding of the natural lens of the eye) are very common, but, fortunately, these can be repaired by a very straightforward operation. A diet rich in antioxidants (like dark fruits and vegetables), not smoking and wearing sunglasses when outside can reduce the risk of developing cataracts.
Another common cause of loss of vision is traumatic eye injury. “Happily, this is preventable by wearing proper eye protection,” states Dr. Frances Story.
“Protective eyeglasses should be worn whenever a chance of eye injury could occur. This includes when using weed trimmers, lawnmowers, saws of any kind, grinding, hammering, working above your head, bicycling, tennis, racquetball, and riding a motorcycle.”
Dr. Scott concludes, “It is important to see an eye care professional for regular eye exams so any problems can be caught and treated early. With proper care and protection your eyes should serve you well for a lifetime!”
