Abstract
Description
Technical Field
[0001] This utility model relates to the field of myopia glasses technology, specifically to a myopia management lens and frame glasses. Background Technology
[0002] Eyeglasses are the most common vision correction tool, widely used to correct eye problems such as myopia, hyperopia, and astigmatism. While eyeglasses effectively improve vision and help wearers see more clearly, existing eyeglasses only provide clear vision while worn; they do not address the root cause of myopia—the change in eyeball shape. Myopia is caused by an elongated eyeball or excessive corneal curvature. Eyeglasses can only correct vision through refractive power, but cannot change the structure of the eyeball or slow down the growth of the axial length. Therefore, myopia may continue to worsen over time. To address this, we propose a myopia management lens and eyeglasses. Utility Model Content
[0003] The purpose of this invention is to provide a myopia management lens and eyeglasses to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a myopia management eyeglass lens and frame eyeglasses, comprising a lens body, the surface of the lens body being an optical zone, the optical zone forming the base surface of the lens body and having refractive power based on the eye's prescription, the optical zone being a central optical zone and a control zone located in the central region of the lens body, the control zone radiating outwards in a ring shape, the central optical zone having a diameter of 6.5mm, the control zone being composed of multiple small convex lenses with positive diopter and small diameter ≥0.8mm, the first to seventh rings of the small convex lenses being arranged in a ring shape, the small convex lenses being configured in a ring shape so that the wavefronts formed can be superimposed on the working focal plane of the optical zone to form a uniform blur spot, the blur spot being able to form a blurred peripheral visual image.
[0005] The refractive power Q1 of the lens and the refractive power Q of the corresponding optical zone satisfy the following relationship: Q = Q1 + ADD, where ADD is the additional refractive power of the small convex lens, which is taken between 3.00D and 4.50D.
[0006] Among them, the small convex lenses are arranged in a regular ring and are uniformly symmetrical. The refractive power of the lenses does not affect the additional cylindrical lens. The small convex lenses are formed on the front surface of the lens body, referred to as surface A. At least 90% of the small convex lenses in the same ring have the same surface shape and refractive power, so that the wavefront generated by this part has the same phase lead relative to the wavefront generated by the lens body. The surface shape of the small convex lenses is selected from circles.
[0007] The central optical area has a circular surface with a radius r ranging from 3 mm to 6 mm.
[0008] Among them, the surface shape of the lens body and the small convex lens is a control ring sub-unit, N is the small convex lens, and N is an integer taken from 1 to 50.
[0009] There is a distance between the outer edge of the control area and the outer edge of the lens body, and the outer edge of the control area is circular in the direction of the normal to the center of the lens body.
[0010] The small convex lenses in the control area are arranged in a ring so that the eye can distinguish the image through the small convex lenses.
[0011] The surface of the lens body is coated, and the coating has a higher hardness than the base material of the lens body.
[0012] The optical area and the control area are integrally formed. The control area is formed on the object-side surface of the lens body away from the eyeball, or on the eyeball-side surface of the lens body close to the eyeball.
[0013] Among them, eyeglasses include frames and temples, and eyeglasses also include lenses.
[0014] This utility model has at least the following beneficial effects:
[0015] These lenses can deeply modulate the image quality of the image plane on the retina. The diffused light spot, through the convergence and scattering of light, allows the retina to focus after farsighted accommodation, which is beneficial for defocus recognition training, thereby achieving the effect of myopia management.
