Description

Technical Field

[0001] The present application relates to the field of defocus lenses, and in particular to a composite film layer resin defocus lens. Background Art

[0002] Defocus lenses are a specially designed type of eyeglass lens, which is intended to correct vision problems and slow down the progression of myopia. The design principle of this lens is based on the visual feedback mechanism of the human eye, and it slows down the progression of myopia by changing the growth pattern and refractive development of the eyeball. Defocus lenses are mainly designed for myopic defocus phenomenon. The design principle of defocus lenses is to add specific optical elements to the lenses so that the lenses can improve peripheral vision while correcting central vision. In this way, when the eyes are looking at close objects, the lenses can reduce excessive adjustment of the eyes, thereby reducing the occurrence of myopic defocus phenomenon.

[0003] With respect to the above-mentioned related technologies, the inventors believe that, when conventional lenses are installed, they are often installed in the frame with the help of clips or wires, while the defocused lenses have complex aspherical surfaces instead of traditional convex or concave mirror surfaces, which makes it easy for the lens to be unable to be installed due to insufficient thickness when the periphery of the lens is grooved.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0011] Preferably, a limiting bolt is fixedly mounted on the surface of the adjusting gear, and the surface of the limiting bolt is engaged with the inner wall of the mirror frame.

[0012] In summary, this application includes the following beneficial technical effects:

A card block is slidably connected to the inner wall of the placement slot, and the card block is clamped with the inner wall of the card slot, so that the lens is installed in the frame, which effectively reduces the range of the groove around the lens and avoids the situation that one side of the lens is thin and difficult to groove. Limit blocks are installed on the surfaces of the two card blocks, and the inner wall of the limit block is threadedly connected with two fixing bolts.

Compared with the prior art, the problem that the defocus lens is too thin to be installed is effectively solved.

[0014] A connecting block can also be installed at one end of the bracket, and a rotating block is rotatably installed at one end of the connecting block, and one end of the rotating block is rotatably connected to one end of the frame.
