Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of eyeglass lenses, in particular to an eyeglass lens combining dot matrix and defocus technology. Background Art
[0002] The number of myopic teenagers is increasing, myopia is occurring at a younger age, and the rate of high myopia is also continuing to rise. Newborn babies are farsighted, and become emmetropes as they grow. If they develop too quickly, they will become myopic. The rapid development of the eye axis has the greatest impact on the occurrence and development of myopia.
[0003] Myopic defocus lenses utilize the principle of myopic defocus. While correcting central refractive error, they utilize peripheral relative positive power to correct the hyperopic defocus of the peripheral retina of myopia, thereby inhibiting the axial length growth and myopia progression induced by the hyperopic defocus of the peripheral retina, so as to delay the worsening of vision. They are widely used in current life. The existing myopic defocus lenses have a uniform medium as the lens body. When light passes through, regular changes occur, causing the image to be refracted onto the retina and in front of the retina, thereby inhibiting the worsening of vision while correcting vision.
[0004] The prior art also combines dot matrix with defocus technology, which can effectively reduce contrast, brightness, and hue differences. The defocus effect of the defocus area can effectively inhibit the deepening of vision, and the effect of delaying vision is significant. However, the dot matrix area and the defocus area in the prior art are mostly overlapped together, which will cause dizziness when the eyeballs move quickly during use. Utility Model Content
