Glasses should generally be worn often because they normalize the refractive error of the eye and allow it to approach or achieve the ability of a person with normal eyes. Wear the right glasses, everything will change, provide close to or reach the normal child should have the prerequisite, may help him become a promising talent, do not underestimate the role of glasses. Farsighted people, reading than normal eyes to use different degrees of adjustment, easy to produce visual fatigue, see the word blurred, eye fatigue, eye pain and even headaches, irritability and other symptoms, so reading can not last, affect the work and study. People with obvious astigmatism have similar symptoms, which disappear when they wear glasses. Therefore, whether it is myopia, farsightedness, astigmatism with glasses generally should be worn often.

    Many myopic patients have heard that people often wear glasses myopic will worsen, the degree will be more and more deep, and do not want to often wear glasses. In fact, this statement and practice is wrong. People with myopia can't see distant objects clearly because the parallel light rays entering the eye focus in front of the retina. If you wear the right pair of glasses, you can move the image in front of the retina back, right on the retina, so that you can see clearly at a distance, and there is less chance of causing eye strain. After people with myopia wear glasses, the degree of myopia is generally not deepened, because whether the myopia is aggravated has nothing to do with the glasses (but not according to the degree of glasses except). Some patients with glasses, while wearing, while not wearing, so easy to cause eye fatigue, and increase myopia.
