Description

Series micro-lens for inhibiting myopia development

Technical Field

The utility model relates to an optical lens piece technical field, concretely relates to myopia development lens of suppression of series connection microlens.

Background

The prevalence rate of the myopia of teenagers in China shows the tendency of low age and high degree of the myopia and increases year by year, the main reason for the occurrence and the development of the myopia of the teenagers is the peripheral hyperopic defocus of retina, and at present, effective myopia correction methods comprise drug control, frame glasses, corneal contact lenses, excimer laser corneal refractive surgery and the like. From the current market feedback, framed glasses are also the primary corrective modality for the vast majority of myopic people and the first choice for controlling myopia progression, where peripheral defocus framed glasses are a more effective and progressively accepted class of lenses by consumers to slow down axial elongation by reducing the principle of retinal peripheral hyperopic defocus. Specifically, the myopia degree of the lens gradually decreases from the top to the bottom, so that the wearer can respectively adopt different degrees when seeing objects with long distance and short distance, and the purpose of relaxing and adjusting eyes is achieved. When ordinary frame glasses are worn, hyperopic defocusing can occur at the periphery of the retina, namely, the peripheral focus is located behind the retina, and peripheral defocusing lenses can change the hyperopic defocusing at the periphery of the retina into myopic defocusing, so that the increase of the axis of the eye is inhibited, and the purpose of controlling the degree is achieved. However, in the conventional defocusing lens, defocusing amount compensation values with different increments are difficult to be configured according to the tolerance degree of the defocusing amount, the increase of the eye axis is difficult to be inhibited, and visual fatigue is easy to generate; in addition, the defocus lens is difficult to perform diopter astigmatism suppression on myopic children with astigmatism, and the use effect is poor.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a rotationally symmetric design of a myopic out-of-focus ophthalmic lens [ CN215340580U ], which includes a central clear vision zone, a myopic out-of-focus compensation zone, and an astigmatism optimization zone. Determining the half-aperture position of the lens according to parameters such as lens eye distance, eye axis rotation center and the like respectively corresponding to half field angles of 10 degrees, 20 degrees and 30 degrees in the myopic defocus compensation area of the lens, setting a myopic defocus compensation value reference point, superposing photometric errors in the oblique axis aberration of the lens according to peripheral defocus detection data, and forming myopic defocus at the corresponding position; meanwhile, defocusing amount compensation value products with different increments can be configured according to the tolerance degree of the wearer to the defocusing amount, so that the wearer is helped to achieve the effect of delaying myopia deepening more accurately and effectively.

The above scheme solves the problem that the defocus lens in the prior art is difficult to configure defocus compensation values with different increments according to the tolerance of defocus to a certain extent, but the scheme still has many defects, such as: it is difficult to perform astigmatism inhibition with diopter for myopic children with astigmatism, and the using effect is not good.
