We humans are only born with one set of eyes, so it's our job to take care of them for our whole lives. The good news is that if we do a few simple things every day, we can maintain (保持) our eyesight and reduce (减少) the risk of ever hurting our eyes.
Almost all doctors agree that we can improve and maintain good eyesight by eating lots of fresh fruits and vegetables. It is especially important for us to eat vegetables like carrots and sweet potatoes. Besides, we need to protect our eyes when we spend a long time in bright sunlight. The best way to do. this is by wearing sunglasses that have 100% UV (紫外线) protection. What's more, it is necessary to protect our eyes when we work with dangerous chemicals (化学物质). For this reason we should always wear goggles in chemistry labs at work or at school. Finally, we should not spend too much time in front of the computer or television screen. That is why doctors advise if we have to use a computer for a long time, we should take a short break every fifteen or thirty minutes.
Maintaining good eyesight is important. If we do these few simple things we can protect our eyes and reduce the chances of losing our eyes. As the popular English expression goes, “It's all fun and game, until someone loses an eye.” When people say this, they mean that losing an eye is a very terrible thing.
