Hyperopic peripheral defocus (None (no common abbreviation))

Hyperopic peripheral defocus refers to a condition where light rays entering the eye are focused behind the peripheral retina, while the central rays may be properly focused on the retina. This effect is commonly seen in myopic eyes corrected by traditional glasses or contact lenses, where peripheral rays focus farther back than the central rays. Extensive research, especially by Dr. Earl Smith and other groups, suggests that the presence of peripheral hyperopic defocus may signal the eye to continue growing axially (getting longer), which in turn leads to myopia progression in children. New strategies to slow myopia progression commonly use specially designed optical devices (multifocal contact lenses, progressive spectacle lenses, orthokeratology) to produce peripheral myopic defocus, redirecting the peripheral light rays to focus in front of the retina, thereby discouraging excessive eye growth. Hyperopic peripheral defocus is thus an optical risk factor or modulator in eye development, not a molecular therapeutic target. It is incorrectly classified as a "target molecule/receptor" in the context of therapeutic drug or molecular research.
