Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of optical design on the lens surface, and specifically relates to optical glasses lenses.
Background Art
[0002] With the popularization of electronic products, mobile phones, tablets, and personal computers have all become devices commonly seen at home. Prolonged use of electronic products causes eye fatigue, leading to myopia and deepening of refractive power. There are many ways to relieve fatigue and protect the eyes, and there are also many ways to relieve myopia. Wearing optical glasses is one of the relatively simple and effective ways to relieve eye fatigue.
[0003] Problems of the prior art: Currently, while the spectrum of sunlight is wide-ranging and continuous, the spectral distribution of artificial light sources is discontinuous, with individual peaks in the visible light region. This not only promotes the growth of the human eye axis and causes myopia, but also leads to the growth of the eye axis.

Each concentric "Bagua" is composed of 8 discontinuous "sides", and each "side" is arranged with continuous foci. The outer contour of the foci is a circle, the radius R is 0.5 mm, and the distance L between adjacent continuous focus centers is 1 mm.

Each concentric "Bagua" is composed of 8 discontinuous "sides", and each "side" is arranged with continuous foci. The outline of the foci is a circle, the radius R is 0.5 mm, and the adjacent and continuous foci may have a center-to-center distance L of 0.75 mm.
