William Blake described the eyes as the “windows of the soul.” Our eyes are the windows through which we see the world around us. Either way，there’s no question that we place great value on our eyes and our eyesight. Surveys have shown that of the five senses，sight is the one that people fear losing the most.
Thinking about the important function of our eyes，we’d give them the best care possible， but sometimes we get too busy or forget to do a few simple things that can keep our eyes healthy.
Protecting your eyes starts with the food on your plate. Remember when you were a kid and your mom told you that carrots would improve your eyesight. Well, she might be right. Proper food will keep your eyes strong and healthy.
Give up your daily habits that could seriously injure your eyes. Always wear sunglasses in a sunny day to protect your eyes from Ultraviolet ray（紫外线）. Rest your eyes every 20 minutes from the computer screen by looking 20 feet away for 20 seconds. At least every 2 hours, get up and take a 15-minute break when working at a computer.
Make sure your eyes do not get injured in the first place. You should try to prevent eye injuries whether you’re playing sports or doing housework. You should also know when to wear safety glasses and what kinds will work best for you.
Last but not least, get your eyes examined regularly. Eye exams can help find some eye diseases. It’s important to find these diseases early on, when they’re easier to treat.
