Technical Field
The utility model relates to a concentric columnar microstructure zoom lens, and belongs to the technical field of zoom lenses.
Background
When the imaging plane is manually moved behind the retina by the negative lens (i.e., distance vision defocus), the ocular axis growth is stimulated and myopia progression may be promoted; when the imaging plane is manually moved in front of the retina by the positive lens (i.e., myopia defocus), the growth of the eye axis is inhibited, possibly inhibiting the progression of myopia. Based on this principle, a number of optical products have been developed that aim to slow down the progression of myopia.
The axial length of the human eye shortens more slowly during near-sighted defocus than during far-sighted defocus, and the human eye reacts more permanently to near-sighted defocus than to far-sighted defocus after defocus stimulus is removed. Thus, studies that selectively intervene in peripheral retinal defocus to affect refractive development and eye growth might provide a new approach to myopia control.
The traditional aspherical microlens designed by concentric circles can lead light to form an unfocused light beam band, and a signal area for slowing down the growth of an eye axis is generated in front of retina, so that the function of slowing down myopia progression is exerted, and compared with the honeycomb design defocusing lens with the spherical microlens, the concentric ring with HAL has smaller influence on far vision and contrast sensitivity of a wearer.
In view of the above-mentioned prior art, the present inventors found that, although the existing aspherical microlens with concentric circle design delays the progression of myopia to some extent, the nested structure of the annular protrusions on the concentric circle causes long-time visual fatigue of the wearer after imaging, which affects the wearing effect, resulting in the problem of poor definition in the actual use process.
