● Using the peripheral defocus control technology, the power of the lens decreases from the optical center to the edge of the lens, which effectively reduces the peripheral hyperopia defocus phenomenon, thereby delaying the elongation of the eye axis and slowing down the development of myopia. ● Optical software was used to calculate the imaging state of the lens when the chief ray was compensated by the dioptric power when the lens was projected obliquely, and the optimized design of the lens was carried out on the basis that the peripheral retinal imaging was in a myopic defocus state. ● Using the substrate anti-blue light technology, it can effectively block more than 25% of blue light and 99% of ultraviolet rays and other harmful radiation.
