Peripheral hyperopic defocus
WebNov 14, 2024 · Peripheral hyperopic defocus happens when myopia is corrected with single vision glasses or contact lenses. The central light rays focus on the fovea and provide a clear image, but peripheral light rays focus behind the plane of the retina, which is thought to play a role in myopia progression, she explained. WebSep 5, 2024 · Animal studies have shown that manipulating peripheral defocus through optical means while simultaneously providing correct axial focus can either discourage or encourage axial eye growth to effectively treat myopia or hyperopia, respectively.
