The reason of cataract is covered in blood supply violation. At the same time food of a crystalline lens worsens, complex irreversible changes of its biochemical structure therefore it loses the transparency begin to happen. At the same time a crystalline lens it is similar to the darkened lens, practically does not install electrical equipment. This pathology is characterized by slow, painless and almost asymptomatic development. At the same time, visual acuity, though extremely slowly, but surely decreases, and in the absence of adequate treatment can lead to a total blindness.
