Nasal bitemporal peripheral out-of-focus spectacle lens based on ocular accommodative convergence

Abstract

The invention discloses a nasal bitemporal peripheral out-of-focus spectacle lens based on ocular accommodative convergence, and belongs to the technical field of the spectacles. The existing myopia spectacle lens cannot simultaneously correct myopia nasal bitemporal retina peripheral asymmetric hyperopic out-of-focus and correct ocular accommodative convergence dysfunction. The spectacle lens facial pattern is set as four areas: nasal side therapy area, a bitemporal therapy area, a central correction area, and an adjusting accommodative correction area; the spectacle lens is set as four types: a progressive multifocal adjusting type nasal bitemporal peripheral out-of-focus spectacle lens and a progressive multifocal accommodative nasal bitemporal peripheral out-of-focus spectacle lens, and a bifocus adjusting type nasal bitemporal peripheral out-of-focus spectacle lens and the bifocus accommodative nasal bitemporal peripheral out-of-focus spectacle lens. The spectacle lens simultaneously posses the functions of correcting myopia nasal bitemporal retina peripheral asymmetric hyperopic out-of-focus and correcting ocular accommodative convergence dysfunction, and suitable for the children and adolescents myopia crowd with primary ocular position, esotropia or exotropia.

Description

technical field [0001] The invention relates to the technical field of glasses, more specifically, the spectacle lens is a spectacle lens based on correcting asymmetric hyperopic defocus around the retina of the nose and temporal side of myopia and correcting esotropia or exotropia myopia. Background technique [0002] The prevention and control of myopia in children and adolescents is a global social problem, and myopia in Chinese children and adolescents is even more serious. Myopia correction for children and adolescents is mainly frame glasses, and the existing myopia glasses are mainly myopia peripheral defocus lenses, progressive multifocal lenses and compound triangular lenses. The existing spectacle lenses have a single corrective function, and none of the spectacle lenses has three corrective functions at the same time. The existing peripheral defocusing frame spectacle lens is designed with the central part of the spectacle lens as a concave lens for correcting th...

Problems solved by technology

[0003] At present, there is no spectacle lens that can simultaneously correct the asymmetry of the nasal and temporal retinal peripheral asymmetry, hyperopic defocus, and correct eye accommodation and correct collective dysfunction. Myopia correction glasses for children and adolescents are still one of the technical problems in the field of ophthalmology and glasses.
