Description
Technical Field
The invention belongs to the technical field of design and processing of optical lenses, and particularly relates to an ophthalmic lens with a surface provided with alternate arrangement of ring belt positive and negative spherical surfaces and cis-trans astigmatic cylindrical microstructures.
Background
Retinal peripheral defocus refers to the ametropia of the eye's refractive system at the periphery of the retina, whereas myopic patients often have retinal peripheral hyperopic defocus, whereas hyperopic patients have retinal peripheral myopic defocus. Clinical studies have found that this hyperopic defocus in the periphery of the retina is one of the key factors in promoting the progression of myopia. The addition of a microlens array in the peripheral region beside the lens is one of the modes of introducing defocus effect at the periphery of the lens, and the lens uses the interference of the refractive power of the microlens to change the refractive structure of the periphery of the lens, thereby relieving the peripheral defocus originally of the wearer.
Aberration refers to the difference between an actual image and an ideal image, and can be divided into lower-order aberration and higher-order aberration. The higher order aberration refers to wavefront aberration of 3 rd order or more in the Zernike polynomial, and is mostly caused by irregular astigmatism, spherical aberration, coma, and the like, and when improperly increased, the visual effect of human eyes is often affected. When high-order aberration opposite to the high-order aberration is introduced into the peripheral defocus region of the retina, the influence on the full-eye refractive power caused by the low-order aberration is small, but visual disturbance can be generated on the peripheral defocus of the retina, so that new peripheral defocus is formed, and the retardation of myopia progression is facilitated. In the prior art, a simple defocus design may increase astigmatism, and a lens structure suitable for teenagers with faster vision development, capable of alternately introducing low-order and high-order aberrations in the peripheral retinal field of view, and a myopic defocus design is needed by those skilled in the art.
