Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lenses, in particular to a dot matrix technology spectacle lens for myopia control. Background Art
[0002] The number of myopic teenagers is increasing, myopia is occurring at a younger age, and the rate of high myopia is also continuing to rise. Newborn babies are farsighted, and become emmetropes as they grow. If they develop too quickly, they will become myopic. The rapid development of the eye axis has the greatest impact on the occurrence and development of myopia.
[0003] Dot technology spectacle lenses reduce image contrast through wide-angle scattering microlenses to simulate the contrast of the natural external environment. Except for the clear optical area with a diameter of 5mm in the center of the lens corresponding to the pupil axis, all other areas are transparent irregular wide-angle scattering microlenses, which can reduce the contrast of a large range of spatial frequencies while minimizing the impact on vision.
[0004] However, the existing dot matrix lens center area of the dot matrix technology eyeglass lens in the prior art is too small and conventional, which is difficult to adapt to in the initial stage of wearing, has safety risks during walking and exercising, and has low adaptability. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a dot matrix technology eyeglass lens for myopia control in view of the deficiencies raised in the above-mentioned background technology.
[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a dot matrix technology eyeglass lens for myopia control, including a lens body, a circular functional area is provided inside the lens body, the functional area includes an external dot matrix area and an internal main optical correction area, the main optical correction area is circular, and a plurality of secondary optical correction areas are provided on the outside of the main optical correction area.
[0007] Furthermore, the total diameter of the lens body is 75 mm, and the diameter of the dot matrix area is 65 mm.
[0008] Furthermore, the secondary optical correction area is extended in four directions of up, down, left and right of the primary optical correction area.
[0009] Furthermore, the diameter of the primary optical correction zone is 5 mm, and the maximum diameter of the plurality of secondary optical correction zones is 9 mm.
[0010] Furthermore, the lens body is manufactured using a 0.12D precision gradient system, and the maximum tolerance accuracy is increased to ±0.06D, which can make vision clearer, more accurate, and binocular vision more balanced.
[0011] The advantage of the dot matrix technology eyeglasses for myopia control of the utility model compared with the prior art is that: by arranging a plurality of secondary optical correction areas outside the main optical correction area in the middle of the dot matrix technology eyeglasses, the utility model can not affect the myopia prevention and control effect, and the initial wearing adaptation is faster and the safety is higher.
