The conventional explanation for nearsightedness is that it is due to the myopic or elongated shape of the eyeball. But it can be demonstrated that in cases of mild myopia, it is mainly due to the myopic or “bulged” shape of the crystalline lens. This type of refractive error can be corrected by wearing a slightly “flat” pair of contact lenses for about one and a half to two minutes. During this period when the meniscus is still intact, the “draw” from the contact lens is at its maximum. The “draw” produces a stimulation which reestablishes distant focusing without altering the curvature of the cornea. The stimulation activates a neuromuscular response to alter the curvature of the crystalline lens.

After removing the contact lens, the crystalline lens would permanently “flatten” out accordingly to bring about distant focusing. The crystalline lens will still retain its ability to flex to a “bulged” shape for near focusing. The method of treatment is called orthoculogy (or ortho C). It is Latin for correcting the whole eye as oppose to just a part of it––such as the cornea by means of orthokeratology or the lens by means of intraocular lens implant.

Orthoculogy can attend to either the myopic shape of the crystalline lens or the sclera. It would attend to both the deviation of the crystalline lens and sclera in severe myopic cases. With mild myopic cases, it is only necessary to attend to the crystalline lens.
