As an eye doctor, I often see students with poor eyesight or eye problems. They always ask me how to take care of their eyes. In fact, many eye problems can be avoided if you will only take some simple steps. For example, don’t spend too much time staring at your computer screen. It can hurt your eyes. When you’ve used your eyes for a long time, for example, working on the computer, watching TV or reading a book, you need to take a break. You need to relax your eyes and do eye exercises. Always make sure that you have enough light when you’re reading. At the same time, you should never look into a bright light, such as the sun. And, if you’re going to be out in the sun for a long time, you need to wear sunglasses. Now many students’ eyesight is damaged and some students even go blind because of accidents, so you should be careful when you’re doing science experiments. If harmful chemicals get into your eyes, be sure to wash your eyes gently with water. Finally, eating a lot of green vegetables can help protect your eyesight. One of the most valuable things you have is your eyesight, so start to protect your eyes now.
