AI Technical Summary
While existing myopia control lenses slow the progression of refractive errors in the eye, they often lead to decreased visual acuity and visual artifacts, causing discomfort, especially for young people.
Design an optical lens comprising a microstructure pattern to generate a constant phase shift difference in the pupil region, reducing image contrast in a specific wavelength range while maintaining good visual sensitivity in other wavelength ranges. The differential optical path map between a first optical path difference map and a second smoothed optical path difference map generated in the pupil region by the microstructure pattern is constant, and the image quality at the first wavelength is at least 10% lower than that at the second wavelength.
It effectively slows the progression of refractive errors in the eye while maintaining the wearer's optimal visual acuity, reduces image contrast in a specific wavelength range, improves peripheral vision, and maintains the clarity of central vision.
