How to Protect Your Eyesight?
Author: Gary Heiting, OD
To protect your eyesight and keep your eyes healthy as you age, consider these simple guidelines:
- Find out if you are at higher risk for eye diseases. Be aware of your family’s health history. Do you or any of your family suffer from diabetes or have a history of high blood pressure? Are you over the age of 65? Are you an African-American over the age of 40? Any of these traits increase your risk for sight-threatening eye diseases. Regular eye exams are particularly important, because an early diagnosis can limit any vision loss and help preserve your eyesight.
- Have regular physical exams to check for diabetes and high blood pressure. If left untreated, these diseases can cause eye problems. In particular, diabetes and high blood pressure can lead to conditions such as diabetic retinopathy, macular degeneration, glaucoma and ocular hypertension.
- Look for warning signs of changes in your vision. If you start noticing changes in your vision, see your eye doctor immediately. Some trouble signs to look for include double vision, hazy vision and difficulty seeing in low light conditions. Other signs to look for are frequent flashes of light, floaters, and eye pain and swelling. All of these can indicate a potential eye health problem that demands immediate attention.
- Exercise more frequently. According to the AAO, some studies suggest that regular exercise — such as walking — can reduce the risk of age-related macular degeneration by up to 70 percent.
- Protect your eyes from harmful UV light. You should always wear sunglasses with proper UV protection to shield your eyes from the sun’s harmful ultraviolet rays. This may help reduce your risk of cataracts and other eye damage.
- Eat a healthy and balanced diet. Numerous studies have shown that antioxidants can possibly reduce the risk of cataracts. These antioxidants are obtained from eating a diet containing plentiful amounts of fruits and colorful or dark green vegetables. Studies also have shown that eating fish rich in omega-3 fatty acids may reduce your risk of developing macular degeneration. Also, consider supplementing your diet with eye vitamins to make sure you are getting adequate amounts of the nutrients you need to keep your eyes healthy.
- Get your eyes checked at least every two years. A comprehensive eye exam, including dilating your pupils, can determine your risk for major eye diseases such as diabetic retinopathy, which has no early warning signs or symptoms. An eye exam also can ensure that your prescription for eyeglasses or contact lenses is up to date.
- Don’t smoke.The many dangers of smoking have been well documented. When it comes to eye health, people who smoke are at greater risk of developing age-related macular degeneration and cataracts.In addition to following these guidelines, be sure to wear safety glasses when working with tools or participating in active sports to help prevent eye injuries that potentially could cause permanent vision loss. It’s true that following these steps is no guarantee of perfect vision throughout your lifetime. But maintaining a healthy lifestyle and having regular eye exams will certainly decrease your risk of developing a sight-stealing eye problem that otherwise might have been prevented.
