Form deprivation myopia occurs when the eyesight is deprived by limited illumination and vision range, [79] or the eye is modified with artificial lenses [80] or deprived of clear form vision. [81] In lower vertebrates, this kind of myopia seems to be reversible within short periods of time.
Contact lenses cause corneal neovascularization because they restrict oxygen diffusion to the corneal epithelium. In the short term, the cornea responds to oxygen deprivation by increasing blood flow to the corneal limbus, the narrow circular border between the cornea and sclera. Over time, this chronic limbal hyperemia can progress to corneal ...

Deprivation Amblyopia: This occurs when something obstructs light from entering the eye, preventing proper vision development. A congenital cataract is an example of such a condition. Strabismic Amblyopia: The most common form, this type arises when the eyes are not properly aligned, leading to double vision. To avoid confusion, the brain ...
