Technical Field
The utility model relates to a clear imaging sphere column composite micro-lens array lens, belonging to the technical field of lens preparation.
Background
At present, the most frequent eye disease among teenagers is myopia, which is the main eye disease that impairs vision. Myopia is a public health problem and the age at which myopia occurs is younger. The eyewear industry and related businesses have begun to produce and sell myopia control products for many years, wherein frame eyewear lens products have evolved from early bifocal and progressive lenses to peripheral myopia progression-slowing lenses that were about ten years ago.
Wearing ordinary frame glasses can increase peripheral retinal hyperopia while correcting central refractive errors and slow down myopia progression, especially for moderately myopic patients. The spectacles for reducing the paracenter and slowing down the myopia progression can ensure that the center focus falls on the center area of the retina, and ensure that the peripheral focus is as close to the retina as possible, thereby reducing the overgrowth of eyeballs caused by peripheral hyperopia and slowing down the myopia progression, and further achieving the effect of slowing down myopia deepening.
In view of the above-mentioned drawbacks, the present inventors have actively studied and innovated to create a clear imaging sphere-column composite type micro-lens array lens, which has a more industrial application value.
