The age-old adage "practice makes perfect" applies nearly to everything in life. It is always necessary to make much effort in order to get something. Body health including the eyes is similar in this case. One of the essential parts of keeping eye health is eye exercises. Some people think that their eyes do not need regular exercises if they are not strained. This is incorrect.
The eyes are quite delicate that they need regular protection and practice. A good testimony to the necessity of eye practice is the lazy eye, which is a relatively common eye problem in some children. Just as the name suggests, the eyes are too lazy. Without proper practice, one of the eyes can not adjust focus between near and distance objects. The most common approach to practice of the weak or lazy eye is patching the opposite eye. In this way, the weak eye is forced to make more practice in perceiving both far and near things, gaining vision synchronization ability. This is a good example of eye practice.
People with unimpaired eyes use their eyes every day more or less. In fact, the eyes can easily get strained. Eye strain and stress occur on a daily basis. If they are not properly relieved, chronic tension would accumulate, leading to visual errors such as myopia and hyperopia. Eye exercises are the right way to prevent chronic eyestrain and stress form settling down. Daily movement and contraction of eye muscles during eye exercises can help the eyes be free from those common refractive errors. Performing eye exercises also requires a person to take at most half an hour. One of the common eye exercises is palming.
Another aspect of eye practice is to keep the eyes lubricated by blinking. The coat of moisture on the eyes is powerful that it can wash away any harmful particles such as dust. In this case, it is quite necessary to keep proper eye blink.
