How to Improve Eyesight Naturally

Eyes are important for everybody. You must take care and try everything in your hand to keep them in good condition. Here are some of the tips to improve your eyesight naturally.

1.     Strain is known to be a factor in many health conditions and eyestrain（眼疲劳） is no exception. Try meditation, yoga or other methods of stress relief to improve your vision and overall health.

Sit upright in a comfortable chair.   2.    Cup your hands so that there is no pressure on your eyes. Let your fingers rest across your forehead. There should be no light entering your eyes. Palming（手掌按摩）should be done for a period of 5 to 10 minutes to start. Palming should be relaxing. It may help to do palming in a darkened room.

3.     It will unpleasantly affect your eyesight, which affects the eyes by producing a larger amount of insulin (胰岛素) in the blood. Therefore you shouldn’t be having much fruit juice or something that contains a lot of sugar.

The only exercise most eyes get is that daily rubbing we give them when we're tired or suffering from eyestrain. But eye exercises are actually good for your eyes and can improve your vision.     4.    Blink as fast as you can for a few seconds then close your eyes tightly, open and repeat. Do this exercise 3 to 4 times daily.

You probably hear that statement all the time but eating the right foods are necessary to good health.     5.   Foods that are high in fiber, vitamin C, D and beta carotene as well as other vitamins and minerals can help improve your vision. Here are a few foods that can be beneficial to good vision: carrots, eggs, blueberries, spinach, kale, grapes, and fresh garlic.

A. Reduce eyestrain.

B. Keep your eyes moist（湿的）.

C. Sugar is your eye’s worst enemy.

D. Give your eyes a workout with the following exercise.

E. You may not be aware that your diet affects your vision but it does.

F. Close eyes and cover them with the palms of your hands.

G. Be sure to get plenty of sleep so your eyes don’t strain to stay open during the day.
