Children become scattered, stoops when considering the figures, often complain of headaches. Among children in the present time increased dramatically short-sighted. Farsightedness – there are two types: natural, child and the usual far-sightedness. With farsightedness closest point of clear vision has always separated from the retina with normal vision. As the forces of accommodation in part used to install into the distance, then its remaining forces are not sufficient for a clear vision of objects vblizi.Ostrota view.
