Summary

Description
English: Typical myopia is due to an elongation of the antero-posterior diameter of the eye, so that the retina is situated behind the principal focus, and only divergent rays of light from a near point (EB1911 Vision - Myopia (1).jpg), or parallel rays made divergent by a concave glass (this figure), can come to a focus on the retina.
