Nowadays most people have bad eyesight. Don’t take your eyes for granted. Here are some tips to protect your eyesight.
Eat for good vision.
Protecting your eyes starts with the food on your plate. Nutrients such as vitamin C and vitamin E may help ward off (避免) vision problems. 26 You can choose green vegetables, eggs, beans and other non-meat protein sources.
Wear sunglasses for good vision.
27 Choose sunglasses that block 99% to 100% of both UVA and UVB rays. If you wear contract lenses, some offer UV protection. It’s still a good idea to wear sunglasses for more protection.
Quit smoking.
Smoking makes you more likely to get cataracts（白内障）, optic nerve （视神经）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.

Staring at a computer screen can cause so many problems: dry eyes, headaches and neck, back and shoulder pain. To protect your eyes, you can position your computer so that your eyes are level with the top of the monitor. This allows you to look slightly down at the screen. Try to avoid glare on your computer from windows and lights. Use an anti-glare screen if needed. Every 20 minutes, rest your eyes by looking 20 feet away for 20 seconds. ___29___
