1. Find out if you are at higher risk for eye diseases.
2. 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 vision loss from diabetic retinopathy, macular degeneration and eye strokes.
3. 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 are double vision, hazy vision and difficulty seeing in low light conditions.
Other signs and symptoms of potentially serious eye problems that warrant immediate attention include red eyes, frequent flashes of light, floaters, and eye pain and swelling.
4. Exercise frequently.
Studies suggest that regular exercise — such as brisk walking — can reduce the risk of age-related macular degeneration by up to 70 percent.
5. Protect your eyes from harmful UV light.
When outdoors during daytime, always wear sunglasses that shield your eyes from 100 percent of the sun's harmful ultraviolet rays. This may help reduce your risk of cataracts, pinguecula and other eye problems.
6. Eat a healthy and balanced diet.
均衡飲食控制
Research has shown that antioxidants

can possibly reduce the risk of cataracts. These antioxidants are best 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.
7. Have an annual eye exam.
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 and that you are seeing as clearly and safely as possible.
8. 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, cataracts, uveitis and other eye problems.
Bonus tip: Safety glasses
Be sure to wear safety glasses when working with tools (especially grinders and other power tools) or participating in active sports. Most work- and sports-related eye injuries that can cause permanent vision loss can be prevented with safety eyewear.
