WatchIf to give him with a vice moderate convex glasses, through it to light the set of function, like moved to the retina from behind, so also be clear ab…out.And LaoGuang, because the regulatory role of the lens lost flexibility, can’t moderate thickening, so to outside light can not very well set, so see nearly can’t clear;If he deserve to a pair of glasses, help the light burning, then, look set nearly be clear about.As for astigmatism, majority is due to the degree of curvature of the cornea changing, or refractive system is not normal, make the eye appears the two objects like, have a plenty of a in the retina, face another is the nuclear surface or behind, may also be a on the other side;If he deserve to all round glasses, use that according to mirror kimono mirror in one area, only to have in the fall, refractive in front or back in another like, moved to the retina, become a like, we also see clearly.So have myopia, farsightedness, astigmatism or the people invited light need glasses.
