Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] refer to Figure 1 to Figure 3 , a microprism lens, the microprism facing the direction of the field of view of the human eye is regarded as a central prism, and its corresponding light incident angle is zero degrees; the microprism array on its left side is regarded as a left prism, and its right side The microprism array is regarded as the right prism; it is characterized in that, the base angle of the central prism is set as α, the value of the base angle α can be determined according to the prismatic lens required by the strabismus patient, and the microprisms on both sides of the central prism are The base angle is α m , m refers to the mth microprism on the left or right side of the central prism; the distortion of light incident from the left prism is calculated by the left distortion coefficient D L Represented by the exit angle θ of the light L 'to t...

Abstract

A method to solve the distortion of the microprism lens, the microprism facing the direction of the field of view of the human eye is regarded as the central prism, and its corresponding light incident angle is zero degrees; the microprism array on the left is regarded as the left prism, located The microprism array on the right side is regarded as the right prism; by changing the prism degree of the microprism lens, the bottom angle of the microprism structure is changed in essence, so that the object image angle after the light passes through the microprism lens does not change. The prism degrees of the left prism and the right prism are determined by the left distortion coefficient D L and the right distortion coefficient D R Determined, the left distortion coefficient D L and the right distortion coefficient D R Take 1. The invention solves the problem of image distortion caused by the microprism lens.

Description

technical field [0001] The invention relates to a method for solving the distortion of a microprism lens and the microprism lens, which solves the problem of image distortion caused by strabismus patients when wearing the microprism lens, and helps the patients recover the ability of binocular monovision. Background technique [0002] Strabismus is a relatively common eye disease in children. According to literature research, the incidence of strabismus in children worldwide is as high as 2%. Strabismus disease not only affects children's eye development, severe strabismus may even affect the development of children's whole body bones, causing irreversible damage. In recent years, strabismus corrective lenses have begun to be used in the direct treatment of children's strabismus or as an adjuvant treatment before and after surgery. Reports from medical institutions show that strabismus corrective lenses have achieved good clinical results in the treatment of recessive strab...
