Astigmatism 175 degrees. That's serious.

Astigmatism refers to parallel light rays entering the eye, after refraction by the eye's refractive system can not focus on a point, nor can it present a clear image on the retina. Astigmatism is a kind of refractive error, refractive error includes myopia, hyperopia and astigmatism. Astigmatism can be divided into mild astigmatism, moderate astigmatism and severe astigmatism. Astigmatism below 100 degrees is generally physiological astigmatism, 175 degrees is mild astigmatism. There are many ways to correct astigmatism, including glasses, glasses, contact lenses, orthokeratology, etc., but also refractive surgery, including laser correction surgery, posterior chamber intraocular lens implantation surgery. When astigmatism is found, it should be corrected as soon as possible, otherwise it may cause amblyopia. Children under the age of 18 do not advocate surgery, do not advocate wearing contact lenses, etc.
