Embodiment 1

[0028] Personalized resin lens design scheme for night driving for people with myopia and astigmatism:

[0029] (1) The clinical prescription for glasses wearers provided by optometrists must include the subjective optometry results under photopic conditions and the subjective optometry results under scotopic conditions;

[0030] (2) After design, the optical lens is divided into three working areas according to the radial radius with the optical center as the dot: the central optical area, the peripheral gradient area, and the peripheral peripheral area;

[0031] (3) The refractive power of the central optical area of ​​the optical lens remains stable and meets the diopter correction amount P1 under photopic conditions, and the refractive power of the peripheral area remains stable and meets the diopter correction amount P2 under scotopic conditions;

[0032] (4) The diopter correction amount on the peripheral gradient area of ​​the optical lens starts to gradually change in ...

Abstract

A personalized optical lens used for nighttime driving and a design method thereof are disclosed. The optical lens has optical performance of an ordinary resin lens, a central optical area can effectively correct a daytime distance vision refractive error of a wearer, and refractive power of a peripheral gradient area is gradually decreased in a radial direction after an optical design. The optical lens of the invention needs to be optically designed based on an optometry prescription containing photopic vision and scotopic vision, and has distinctive individual characteristics, and is particularly suitable for being worn during nighttime driving. The optical lens is mainly aimed at a problem of deepening myopia at night due to factors of dilated pupils at night, increase of whole eye aberration and the like.

Description

technical field [0001] The invention specifically relates to the technical field of optical lens design, in particular to a personalized optical lens for night driving and a design method thereof. Background technique [0002] Normal human eyes have relatively small pupils during the day, and external light mainly passes through the paraxial area of ​​the lens and converges on the macula of the retina, so that the human eye can see clearly. However, at night, the pupil of the human eye is enlarged compared with the daytime, and the light passing through the peripheral area of ​​the lens is significantly increased. The phenomenon is called nocturnal myopia. It is caused by the special physiological structure of the human eye, including the aspherical surface morphology of the human cornea and lens, and the gradient change of the lens refractive index from the center to the periphery. It can be seen that there is a general difference between the corrected refractive power re...
