Refractive myopia is an ocular refractive disorder in which the light rays from an image focus in front of the retina because the anteroposterior diameter of the eye is longer than normal.. It is the most common type of myopia. It usually begins in young people and may be mild with a non-progressive course at the end of body growth. Three types of refractive myopia are recognized: stationary myopia [myopia - stationary], progressive myopia [myopia - progressive] and late myopia [myopia - late]. Refractive myopia needs to be differentiated from lenticular [myopia - lenticular].
