Yes, many of the visual habits nowadays are bad for our eye health. Computer is one of the worst culprit. We are becoming more and more lazy, even not willing to leave it and take a precious break. Dim the light of your computer screen and don't stare at one point for too long, blink frequently. Take a 10 min’s break every 40~50min. There is nothing more simple and more important than breaking. Always wash your hands and don’t rub your eyes. Often take eye exercises, and pay more attention to our eyes. Wear sunglasses when UV is strong outside, no matter in winter or summer. Don't drink alcohol or smoking, which can worsen dry eye and high intraocular pressure. Eat more food that is good for eyes, such as walnut, peanut, tea of mountain daisy and medlar, black bean, milk, jujube, cassia seed tea, etc. fresh vegetable and fruits are also strongly recommended.
