Optimal low optical aberration anti-myopia scieropia spherical lens

Abstract

The invention relates to glasses provided with myopic-prevention scieropia spherical lenses of optimal low optical aberration. The lenses, which are mainly used for myopic prevention by the 'scieropia method' widely recognized in the medical field to reduce the burden on crystalline lens for myopic prevention, can also be used for reducing the imaging distortion of presbyopic glasses. The glasses can strictly control the optical aberration, avoid imaging distortion, select the optimal design scheme according to different physiological conditions and habits of using eyes of different people, and reduce the cost for using the lenses by half. During fabrication, the optical center is not only moved inwards, but also creatively moved downwards (quantitative), so that a round lens can be cut into two lenses needed by a pair of glasses.

Description

technical field

[0001] The glasses are mainly used to prevent myopia. It uses the "fog vision method" generally recognized in medicine. By using a convex lens to share a part of the curvature of the lens, when people wear it and look at the near (such as reading), the eyes are in the extreme of the lens. The state of being relaxed when looking at a distance can fundamentally prevent the occurrence of myopia and curb the deepening of myopia. Background technique

[0002] Fog vision method has long been generally recognized in medicine. About ten years ago, some people also invented off-centre myopia prevention glasses, which roughly solved the contradiction between collection and adjustment imbalance after wearing foggy glasses. However, he finally gave up the patent because he did not solve the problem of increasing aberrations (including imaging distortion and the difference in the size of the images of the two eyes) after the optical center of the lens moved inward.
