Description

Technical Field

[0001] The utility model relates to the technical field of aspherical lenses, in particular to a double-sided aspherical myopia spectacle lens. Background Art

[0002] At present, aspherical lenses have gradually replaced spherical lenses. The surface curvature of aspherical lenses is different from that of ordinary spherical lenses. In order to pursue the thinness of lenses, it is necessary to change the curvature of the lenses. In the past, the spherical design increased the aberration and deformation, resulting in obvious unclear images, distorted vision, narrow field of view and other undesirable phenomena. Now the aspherical design corrects the image and solves problems such as vision distortion. At the same time, it makes the lenses lighter, thinner and flatter, and still maintains excellent impact resistance, allowing the wearer to use it safely.

[0003] Existing lenses usually lack proper structures for fixation during installation, and thus when they are connected and fixed to the glasses frame, they are often not fixed tightly enough. After long-term use, the glasses frame will be affected by the characteristics of its material itself. For example, some plastics will shrink and deform, resulting in large gaps, and metals will bend and move, resulting in a poor fit.

[0004] Therefore, it is necessary to invent double-sided aspherical myopia lenses. Utility Model Content

It can solve the above-mentioned problem that the existing lenses usually lack appropriate structures for fixing during installation, and then when they are connected and fixed to the glasses frame, the fixation is often not tight enough, and after long-term use, the glasses frame will be affected by the characteristics of its material itself, such as some plastics will shrink and deform, resulting in larger gaps, and metals will bend and move, resulting in insufficient fit.
