“…To correct corneal astigmatism, the ortho C contact lens only needs to "stretch" the oblique muscles sufficiently to allow the crystalline lens to compensate for the distortion of the cornea along a specific meridian [9]. To correct lenticular astigmatism, the ortho C contact lens only needs to "stretch" the oblique muscles sufficiently to allow the crystalline lens to "flatten" along a specific meridian for distant focusing [10].…”

Myopia, or nearsightedness, is not just a physical deviation of the eye; there is also a neurological deviation. The incorrect neuromuscular message is sent for distant focusing because the visual cortex interprets the myopic eye to be in near focus mode. When an effort is made to bring a distant object into focus, the crystalline lens will tend to "bulge" instead of becoming "flat", and the eye will tend to elongate instead of remaining spherical. The visual cortex partially or completely overwrites the information received by depth perception: that the object is far away. The culprit behind this misinterpretation is the spasm of the oblique muscles. How much the neurosensory information is altered depends on the tension of the oblique muscles. If those muscles are partial tight, the visual cortex would send a partially revised neuromotor message; and if those muscles become tighter, the correct neuromotor message for distant focusing would be further revised in favour of near focusing. The premise was demonstrated by applying orthoculogy to treat over 300 patients with myopia. Orthoculogy (or Ortho C) relaxes the oblique muscles to reset the curvature of the crystalline lens and sclera. The following are some indications to demonstrate that the reinstatement of the correct neuromotor message can reverse the effects of myopia: The ability of ortho C to treat myopia without direct physical manipulation of the refractive mediums: the crystalline lens, the sclera, or the cornea. The ability of the visual cortex to discriminate the different treatment options after an ortho C lens just relaxes the oblique muscles. The time it takes to restore the mild or moderate myopic eye to its premyopic shape if the intraocular or extraocular muscles are not compromised: in about 2 minutes.

“…The visual cortex disregards the neurosensory message relayed by depth perceptionthat the object of regard is in the distance instead of close-up. The neurosensory message from the tension of the oblique muscles overrides the message from depth perception 4 perception of a distant object is revised. The visual cortex regards that object to be in the near range.…”

Introduction This paper suggests that asthenopia, or eye strain, initiates a process that can lead to detachment. Asthenopia can be induced in the myopic eye at the near range with a minus lens; and under those conditions, it creates the tendency for one's myopia to become worse. Progressive myopia, past a certain stage, is attributed mainly to the eyeball (or sclera). An excessive elongation of the sclera can lead to detachment. The Hypothesis Asthenopia is often thought to be prevalent in cases of hyperopia when performing close-up work, but it can also be induced in the myopic eye at the near range with a minus lens. A minus lens projects the focal point from a close-up object farther behind the retina. The crystalline lens would have to "bulge" more to bring it into focus-more than how much it would normally "bulge" for near focusing. Under those conditions the myopic eye becomes susceptible to progressive myopia. Evaluation of Hypothesis This means the ciliary muscle, which controls the shape of the crystalline lens, would have to tighten up more. If the ciliary muscle tightens up excessively, the oblique muscles would also tighten up more in response. (The oblique muscles are already tense since the eye is myopic.) The excess tension of the oblique muscles can force the sclera to elongate and thereby reduce the distance between the retina and the focal point. This alleviates some of the strain on the ciliary muscle. The crystalline lens would not have to "bulge" to its maximum-although it would still "bulge" more than how much it would normally "bulge" for near focusing. Conclusion It can be demonstrated that if the eye was continuously subjected to such a condition for an extended period of time, near-point asthenopia can promote progressive myopia. It is attributed to asthenopia because more than the normally required "effort to see" is generated, before a near image could be brought into focus. Not only will the crystalline lens "bulge" excessively, but the sclera will also elongate progressively. Detachment tends to occur at the area where the retina has thinned out due to the continuous elongation of the eye.
