Your eyes allow you to see color, light, buildings and the face of those you love. The eyes are a clear way to feel the world. Here are some tips about how to look after your eyes.
Take an eye break
Many people need to look at computer screens(屏幕)when they work or study. That puts a lot of pressure (压力)on their eyes. So for every 20 minutes spent looking at a screen, you should take an eye break of around 20 seconds. During the break, you should loo at something that is at least 6 meters away.
Wear a sun hat or sunglasses
There are some harmful(有害的)rays from the sun. UV rays(紫外线)can be harmful to the eyes, so it's best to get into the habit of protecting them from an early age. Wearing a sun hat or sunglasses is the best way to protect your eyes.
Eat eye-friendly foods
You can also protect your eyes by eating some eye-friendly foods. Green vegetables and fish are good to keep our eyes healthy.
Have a good sleep
Make sure you have a good night's sleep. You may think you are doing nothing when you're sleeping.But it's time for your body to rebuild and repair(重建和修复). At night, your eyes keep cleaning out the dirty things that come in during the day.
