REFRACTIVE ERRORS-A CONCEPTUAL VIEW

Refractive errors are the common problem in today's life style. When light rays pass from a medium of one density to a medium of a different density they are refracted or bent.So before reaching the retina light rays pass successively through the cornea, Aqueous humour, Lens and vitreous humour which are all more dense than the air. There are 3 types of refractive error Myopia, Hypermetropia and Astigmatism. Timira is one such eye disease, which starts from Avyakta darshana and ends in complete loss of vision i.e. Linganasha.
