Normal vision. Courtesy NIH National Eye Institute The same view when myopic. Myopia, sometimes called near-sightedness or short-sightedness[1], is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed. This may be caused by a defect of the cornea (generally where the cornea protrudes too far outward from the eye) or from elongation of the eye structure itself (generally the eye is too long). Those with myo ...
