AI Technical Summary
In current technology, wearing ordinary myopia lenses leads to an increase in myopia degree, making it difficult to effectively control the development of myopia in teenagers.
A composite multi-point microlens defocus lens was designed. The center of the lens is the central visible area, and the periphery is the defocus area. The defocus area includes an enhancement area and a gradient area. By setting up multiple sets of microlens groups arrayed along a straight path, the design of the microlens groups and the curved lens are used to correct the image in front of or close to the retina, reducing the stimulation of the eyes by the peripheral image.
