Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a single-sided point diffusion myopia optical lens. Background Art

[0002] Myopia is caused by the eyeball's axial length being too long or the cornea being too curved, which causes the eye to focus the image of distant objects in front of the retina, resulting in blurred vision. The traditional method of correcting myopia is to wear spherical lenses, that is, single-focus lenses. Although spherical lenses can present images in the fovea of ​​the retina, the peripheral images of the retina will fall behind the retina, causing hyperopic defocus, further forcing the eye axis to lengthen and deepening the development of myopia.

[0003] Existing myopia lenses are prone to cause optic nerve fatigue, incompletely filter harmful light, and damage eye health. Utility Model Content
