Eyesight is indispensible for nearly everything in daily lives. Most information is acquired through one’s vision, so that keeping good eye health is quite important for everyone. There are some tips that are useful to avoid early signs of weakening or even total loss of eyesight. A first way to strengthen eyesight can be eating a healthy diet. Many people believe that vitamin A found in many foods can help reduce night blindness and other problems. Foods that are plentiful of vitamin A include broccoli, sweet potato, green leafy vegetables and carrots. What’s more important, excessive amount of vitamin A consumption can be toxic, which may lead to problems with the liver. So that it is necessary to maintain sufficient and proper vitamin A intake for vision strengthening. Another method suggested by experts is to use a total range of vision. It is necessary to challenge the eyes to focus on things far and near. Remember that the eyes also need practice, just like other parts of the body. To test the eye’s ability in all ranges of distance, a person can try reading fine print in the phone book and look out for signs that are far away. Sunshine is commonly related to UV light, which scares many people. However, some researches have found that kids who spend more time outside have better vision. This finding means that sunshine may strengthen eyesight. In detail, it is reported that children spending two to three hours outside every day have lower risk of developing myopia. Eyeglasses are widely used to get vision correction. The most critical factor of these devices is exact prescription. Eyeglasses or contact lenses with wrong prescription can cause eye strain and even permanent damage to the eyes. A fact is that hyperopia and myopia in patients will continue to develop, which means update of prescription regularly is needed. Corrective eye surgery is a permanent solution to vision problems. LASIK is the most widely accepted one, which in most cases can restore 20/20 vision or better. This type of surgery involves few complications. A candidate evaluation is also needed.
