Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a myopia prevention and control lens. Background Art

[0002] There are many reasons for myopia, mainly involving genetic factors, environmental factors and lifestyle, among which environmental factors are the most important. As smart devices become more popular and occupy an important position in work and life, people are exposed to and use electronic devices for longer and longer periods of time. Long-term close-range eye use can easily lead to myopia. The most important change after myopia is the extension of the anterior-posterior diameter of the eyeball, that is, the lengthening of the eye axis, which is the anatomical feature of myopia and an important sign of the worsening of myopia.

[0003] Usually, people will wear myopia glasses for prevention and correction after they become myopic, but they can only delay the increase in the degree of the glasses. Because for people's general concern, myopia glasses are just auxiliary vision, helping people to see distant objects clearly, and people will not subconsciously change their eye habits, resulting in poor treatment effect of myopia glasses. Utility Model Content

[0004] The purpose of the utility model is to provide a myopia prevention and control piece to solve the problems existing in the prior art, to forcibly correct the user's eye habits, and to improve the effect of myopia glasses in preventing and controlling myopia and correcting myopia.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0007] The spherical protrusion and the transparent lens are integrally formed through an injection molding process.

[0008] Preferably, the transparent lens obtains the siliconized coating on the surface by immersing it in an organic siliconization strengthening treatment liquid and baking and curing it.

[0009] Preferably, the processing technology of the transparent lens specifically includes the following steps:

[0010] (1) Preliminary preparations for the injection molding and hardening process of the transparent lens are performed in a dust-free workshop, and the operator wears dust-free electrostatic clothing to perform the operation;

[0011] (2) After the transparent lens is injection molded, cleaning and drying it;

[0012] (3) immersing the transparent lens in an organic silicon strengthening treatment solution;

[0013] (4) Dry the hardened transparent lens and clean it.

[0014] In some embodiments, the transparent lens is provided with a group of petals formed by a plurality of spherical protrusions, and the plurality of groups of petals are arranged at equal angles around the center of the transparent lens, and adjacent petals cross and overlap.

[0015] In some embodiments, a group of circles is formed on the transparent lens by a plurality of spherical protrusions, and the plurality of circles are centered at the center of the transparent lens and spread outward at equal intervals along the radial direction of the transparent lens.

[0018] After adopting the above technical solution, the utility model has the following technical effects:

[0019] The utility model uses point diffusion technology to specially design the visible area on the control piece. The control piece can be assembled into the lens of the glasses after cutting. Therefore, only the circular area in the middle of the lens without convex points is the visible area. When the user's glasses focus on this area to see objects, they will not be affected by the convex points and can see objects normally. At the same time, the circular area is also convenient for using a focal meter to measure the degree of the lens, which provides convenience for users when they have fine visual requirements.

[0020] The circular area is covered with regular or irregular convex points, which can affect the line of sight. When the user's glasses focus outside the circular area, it will be inconvenient because the convex points block the line of sight, and it will accelerate visual fatigue. Therefore, this design can force the user to change the eye habits and keep the eyes focused on the same position, thereby achieving the effect of myopia prevention and correction;

[0021] The maximum size of the spherical protrusion is set at 0.3mm so that the spherical protrusion is not easily observed when observing the lens made of the control sheet from a distance, making the lens no different from a normal lens and avoiding psychological distress to users wearing such special glasses.

[0030] Through the above scheme, the utility model uses the point diffusion technology to specially design the visible area on the control piece. The control piece can be assembled into the lens of the glasses after cutting. Therefore, only the circular area 2 located in the middle without convex points is the visible area in the lens. When the user's glasses focus on this area to see objects, they will not be affected by the convex points and can see objects normally. At the same time, the circular area 2 is also convenient for using a focal meter to measure the degree of the lens, which provides convenience for the user when the user has fine visual requirements; and the area outside the circular area 2 is full of regular or irregular convex points, which can achieve the effect of affecting the line of sight. When the user's glasses focus outside the circular area, it will be inconvenient because the convex points block the line of sight, and it will accelerate visual fatigue. Therefore, this design can force the user to change the eye habits and keep the eyes focused on the same position, thereby achieving the effect of myopia prevention and correction; in addition, the maximum size of the spherical protrusion 3 is set at 0.3mm, so that the spherical protrusion 3 is not easy to be observed when observing the lens made of the prevention and control piece at a distance (more than 10cm away from the user), so that the lens is no different from a normal lens, avoiding psychological distress to users wearing such special glasses.

Specifically, organic siliconization can be used for strengthening and hardening: using organic siliconization strengthening treatment liquid, the surface of the transparent lens 1 is soaked to obtain a uniform siliconized coating, and then the surface is cured by baking. This method can significantly improve the hardness of the lens.

[0033] Furthermore, the processing technology of the transparent lens 1 specifically includes the following steps:

[0034] (1) The preliminary preparation for the injection molding and hardening process of the transparent lens 1 is carried out in a dust-free workshop, and the operator wears dust-free electrostatic clothing to prevent contamination and scratches on the lens surface;

[0035] (2) After the transparent lens 1 is injection molded, it is cleaned and dried to remove oil stains and impurities on the surface;

[0036] (3) immersing the transparent lens 1 in an organic silicon strengthening treatment liquid to perform a surface hardening treatment on the transparent lens 1;

[0037] (4) The hardened transparent lens 1 is dried and cleaned to remove the residual processing liquid and impurities on the surface.
