Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to an anti-bending, anti-wear and anti-blue light lens. Background Art

[0002] As resin lenses are becoming more and more popular among consumers due to their advantages such as light weight, vibration resistance, easy dyeing, easy molding, good elasticity, high refractive index, and UV resistance, it is becoming increasingly necessary to process the surface due to their inherent shortcomings such as low surface hardness, easy scratches, and poor thermal properties.

[0003] Blue light is an important component of visible light. There is no separate white light in nature. Blue light is mixed with green light and yellow light to present white light. Green light and yellow light have lower energy and less stimulation to the eyes. Blue light has short wavelength and high energy and can directly penetrate the lens and reach the retina at the fundus. Studies have shown that if photoreceptor cells are exposed to blue-violet light for a long time, the pigment molecules in the cells will trigger a phototoxic reaction, causing lesions in the macula. The stronger the light, the greater the damage. Therefore, macular degeneration is no longer exclusive to the elderly. In today's society, with the change of living habits, long-term exposure to blue-violet light stimulation (such as computers, televisions, outdoor sunlight, etc.), especially in today's era of popularization of televisions, computers, and touch-screen mobile phones, eye health has become a major issue. For normal people like us, blocking long-term exposure to blue light is the most effective way to reduce damage, and using anti-blue light lenses can effectively solve this problem. Ordinary anti-ultraviolet lenses can only filter ultraviolet rays, but not blue light.

[0004] In addition, through actual mass production, it was found that a considerable number of lenses are very likely to bend or be damaged due to external forces after being used for a long period of time. Utility Model Content

[0005] The main purpose of the utility model is to provide an anti-bending, wear-resistant and anti-blue light lens, which strengthens the strength and hardness of the lens as a whole through a protective part, a first hardened layer, a second hardened layer and a double-layer reinforcement layer to avoid bending and breaking due to external forces; by arranging an arc-shaped groove and arranging a positioning block in the arc-shaped groove, the tightness of the connection between the lens and the frame is enhanced; by arranging an elastic block on the positioning block, when the lens is impacted by external force, a certain buffer space can be provided to avoid bending and damage of the lens.

[0006] In order to solve the above-mentioned technical problems, the utility model discloses an anti-bending, wear-resistant and anti-blue light lens, comprising: a base layer, the base layer comprising a central part and a protective part arranged around the outside of the central part; an arc-shaped groove arranged around the outside of the protective part, a positioning block is provided at the bottom of the arc-shaped groove, and an elastic block is provided on the top of the positioning block; a first hardened layer arranged on the outside of the central part, an anti-blue light layer is provided on the outside of the first hardened layer, and a wear-resistant layer is provided on the outside of the anti-blue light layer; a double-layer reinforcement layer arranged on the inside of the protective part, and a second hardened layer is provided on the central part and the inside of the protective part.

[0007] According to an implementation manner of the utility model, the number of the arc-shaped grooves is 3 groups, and the number of the positioning blocks is 9.

[0008] According to one embodiment of the utility model, the thickness of the first hardened layer and the second hardened layer are consistent.

[0009] According to one embodiment of the utility model, the thickness of the double-layer reinforcement layer is 4-6 μm.

[0010] According to an embodiment of the present invention, the central portion and the protection portion are integrally formed.

[0011] Compared with the prior art, the present application can obtain the following technical effects:

[0012] 1) The strength and hardness of the lens are enhanced as a whole by means of the protective portion, the first hardening layer, the second hardening layer and the double-layer reinforcement layer to prevent the lens from being bent and broken by external forces; by providing an arc-shaped groove and a positioning block in the arc-shaped groove, the tightness of the connection between the lens and the frame is enhanced; by providing an elastic block on the positioning block, when the lens is impacted by external forces, a certain buffer space can be provided to prevent the lens from being bent and damaged.
