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.

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.
