Description

Technical Field

[0001] The utility model relates to the technical field of eyeglass lenses, in particular to an eyeglass lens which has a dot matrix with a near use adaptation zone and combines a defocusing 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] Moreover, in actual use of existing myopic defocus lenses, as myopic electronic devices are used, the strong contrast, distance and brightness of electronic devices such as mobile phones and tablets that directly view the display screen at close range will further stimulate the growth of the eye axis, thereby affecting the delaying effect of vision. Moreover, existing myopic defocus lenses are mostly single defocus layers, and the strong contrast and brightness of such close electronic devices will stimulate the growth of the eye axis, thereby affecting the delaying effect of vision.

[0007] Furthermore, the total diameter of the lens body is 75 mm, the diameter of the functional area is 51 mm, and the diameter of the optical correction area is 9 mm.
