How to maintain good eye health
1. Eat for good vision
Protecting your eyes starts with the food on your plate. Nutrients such as omega-3 fatty acids, lutein, zinc, and vitamins c and e might help ward off age-related vision problems such as macular degeneration and cataracts, studies show. Regularly eating these foods can help lead to good eye health:
Green, leafy vegetables such as spinach, kale, and collards
Salmon, tuna, and other oily fish
Eggs, nuts, beans, and other non-meat protein sources
Oranges and other citrus fruits or juices
Eating a well-balanced diet also helps you maintain a healthy weight, which makes you less likely to get obesity-related diseases such as type 2 diabetes. Diabetes is the leading cause of blindness in adults.
2. Quit smoking
Smoking makes you more likely to get cataracts, optic nerve damage, and macular degeneration. If you've tried to quit smoking before and started smoking again, keep trying. The more times you try to quit smoking, the more likely you are to succeed.
3. Wear sunglasses
The right kind of sunglasses will help protect your eyes from the sun's ultraviolet (UV) rays.
Too much UV exposure makes you more likely to get cataracts and macular degeneration.
Choose sunglasses that block 99% to 100% of both uva and UVB rays. Wraparound lenses help protect your eyes from the side. Polarized lenses reduce glare when driving.

If you wear contact lenses, some offer UV protection. It's still a good idea to wear sunglasses for more protection, though.
4. Use safety eyewear
If you work with hazardous or airborne materials on the job or at home, wear safety glasses or protective goggles every time.
Certain sports such as ice hockey, racquetball, and lacrosse can also lead to eye injury. Wear eye protection (such as helmets with protective face masks or sports goggles with polycarbonate lenses) to shield your eyes.
5. Look away from the computer screen
Staring at a computer screen for too long can cause:
Trouble focusing at a distance
