Description
Technical Field
The utility model relates to a discontinuous concentric column microstructure zoom lens belongs to zoom lens technical field.
Background
When the imaging plane is manually moved behind the retina by the negative lens (i.e., hyperopic defocus), the growth of the eye axis 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., myopic defocus), the growth of the eye axis is inhibited, thereby possibly inhibiting the progression of myopia. Based on this principle, many optical products aimed at slowing the progression of myopia have come into play.
The axial length of the eye shortens slower during myopic defocus than it extends during hyperopic defocus, and after defocus stimuli are removed, the eye responds more permanently to myopic defocus than to hyperopic defocus. Therefore, studies that selectively intervene in peripheral retinal defocus to affect refractive development and eye growth may provide a new approach to myopia control.
The traditional aspheric surface micro lens with concentric circle design can lead the light to form an unfocused light band, and a signal area for slowing down the growth of the axis of the eye is generated in front of the retina, thereby playing the role of slowing down the progression of myopia.
In view of the above prior art, the inventor of the present invention finds that although the existing aspheric microlens designed by concentric circles retards the progress of myopia to a certain extent, the problem of poor definition exists in the actual use process of the aspheric microlens due to the inconsistency between the curvature radii of the annular bulge and the base lens on the concentric circles.
