| short sight | <ophthalmology> That error of refraction in which rays of light entering the eye parallel to the optic axis are brought to a focus in front of the retina, as a result of the eyeball being too long from front to back (axial myopia) or of an increased strength in refractive power of the media of the eye (index myopia).
