Hyperopic astigmatism is an ophthalmic disease which is characterized by a violation of the lens or cornea form, so that refracted light is formed in two or more points behind the retina. In the normal structure of the optic body rays are refracted at a single point on the retina, but that does not happen at hyperopic astigmatism, what causes vision problems.
In case of astigmatism treatment is not an easy task! This disease causes violation of refraction. The sphericity of the cornea is changed: when rays pass through it, the perceived image is different from what it really is like. Some lines of the subject the person sees may be clear, the other - vague.
