Nowadays, vision problems including nearsightedness and farsightedness commonly occur in children. It is widely believed that these types of vision imperfection are caused by improper use of children’s eyes during their study and other entertainment activities such as watching TV.

In general, there are two groups of children who need to wear corrective eyeglasses. One is required to wear glasses only when reading the black board in class, writing at home and the like. The other group is advised to have glasses on constantly. This classification is depends on the severity of vision problems.
It is widely known that a heavy prescription always requires a pair of thick lenses which is matched with the latter group aforementioned. In this case, small frames are preferred so as to maintain the accuracy of vision correction. Actually, lenses thickness decided by prescription has a direct impact on frame style. The final decision should be made by the optician.
Another significant aspect is lens type. Among the various lens materials in the market, polycarbonate is the best for children.
