Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a pair of glasses specially used for reading and writing with hyperopia reserve. Background Art

[0002] Visual acuity refers to the ability of the retina to distinguish images. The quality of visual acuity is determined by the ability of the retina to distinguish images. However, when the refractive medium of the eye (cornea, lens, vitreous body, etc.) becomes cloudy or there is a refractive error (including myopia, hyperopia, astigmatism, etc.), the visual acuity of the eye will still decline even if the retina functions well. The turbidity of the refractive medium of the eye can be treated with surgery, while refractive errors need to be corrected with lenses. Wearing vision correction glasses has become the main method to compensate for vision problems. For people with myopia, concave lenses should be worn for vision correction, and for people with hyperopia, convex lenses should be worn for correction.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese patent announcement number: CN216118262U discloses a hyperopia reserve reading and writing glasses, including two frames and two groups of temple parts, the ends of the two frames close to each other are fixedly connected by a connecting piece, and the ends of the two frames away from each other are fixedly installed with placement blocks, the two groups of temple parts are movably installed in the two placement blocks, and lenses are fixedly installed in the two frames. The two lenses are divided into five areas, and the five areas include a middle lens area, an upper concave lens area, a lower concave lens area, a left concave lens area and a right concave lens area. The middle lens area is located in the center of the lens, and the specific structure is a combination of a convex lens and a prism. The upper concave lens area and the lower concave lens area are respectively located on the upper side and the lower side of the middle lens area, and the left concave lens area and the right concave lens area are respectively located on the left side and the right side of the middle lens area. The utility model effectively solves the problems of simple structure and single function.

[0005] However, the above patents still have some problems in actual use. The most obvious one is that the glasses have poor stability during wearing and are prone to shaking or even falling during exercise. Secondly, existing lenses are usually glued to the frames. After choosing and buying glasses, wearers will get tired of the frames over time and no longer like the existing frames after aesthetic fatigue occurs. However, it is difficult for wearers to change different types of frames according to their own preferences at a later stage, and it is difficult to meet the wearer's personalized needs.

[0006] Therefore, we propose a pair of hyperopia reserve reading and writing glasses to solve the above-mentioned drawbacks. Utility Model Content
