Description

Technical Field

[0001] This utility model relates to the field of spectacle lens technology, and in particular to a wear-resistant and high-hardness spectacle lens. Background Technology

[0002] As people pay more attention to their health, more and more people will enjoy outdoor sports, such as cycling, mountain climbing, hiking, and so on.

[0003] During outdoor sports, nearsighted people need to wear glasses. The surface of these glasses will be rubbed by particles and gravel in the outdoor environment. Since nearsighted glasses are generally made of resin lens material, they have weak abrasion resistance. Over time, this will cause wear and tear on the inner and outer surfaces of the glasses.

[0004] Furthermore, when nearsighted people wear glasses for outdoor sports, they may be scratched or bumped by tree branches or other hard objects. Since nearsighted glasses are generally made of resin, they are less resistant to impact, have lower hardness, and are less prone to deformation. This can easily cause deformation, significantly reducing the impact resistance and deformation resistance of nearsighted glasses used for outdoor sports.

[0005] In addition, after the lens body is manufactured, it needs to be assembled into the mounting slot of the frame. During the snap-fit ​​assembly, since myopia lenses are generally made of resin lens substrate, which has weak abrasion resistance, the outer wall of the lens body will be scratched, which greatly reduces the abrasion resistance of myopia lenses for outdoor sports when they are assembled into the frame.

[0006] Therefore, we designed a prescription eyeglass lens for outdoor sports to meet the needs of practical applications. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a wear-resistant and high-hardness spectacle lens.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: Design a wear-resistant and high-hardness spectacle lens, including a spectacle lens body, a first high-hardness inner layer provided on the upper end surface of the spectacle lens body, a first wear-resistant outer layer provided at the end of the first high-hardness inner layer away from the spectacle lens body, a second high-hardness inner layer provided on the lower end surface of the spectacle lens body, a second wear-resistant outer layer provided at the end of the second high-hardness inner layer away from the spectacle lens body, and a first side sleeve and a second side sleeve fitted on the outer side of the spectacle lens body; Both the first and second side sleeves are provided with a main sleeve groove, and a secondary filling groove is provided in the main sleeve groove. A main adhesive layer is provided on the main sleeve groove, and a secondary adhesive layer is provided in the secondary filling groove. The end face of the first side sheath is provided with a first adhesive layer, and the end face of the second side sheath is provided with a second adhesive layer.

[0009] In detail, both the first high-hardness inner layer and the second high-hardness inner layer are silicon-based hardened film layer structures.

[0010] In detail, both the first and second wear-resistant outer layers are zirconium dioxide film structures.

[0011] In detail, both the first and second side sleeves are semi-ring-shaped structures, and both the first and second side sleeves are made of polycarbonate.

[0012] In detail, the front view of the main sleeve groove is a U-shaped structure, and the main adhesive layer is evenly distributed along the inner wall of the main sleeve groove.

[0013] In detail, the sub-filling groove is a rectangular inner groove, and there are forty-nine sub-filling grooves arranged in a circle. The sub-adhesive layer is filled in the sub-filling groove.

[0014] In detail, the first adhesive layer is uniformly coated along the end face of the first side sheath, and the second adhesive layer is uniformly coated along the end face of the second side sheath.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This utility model provides a first high-hardness inner layer and a second high-hardness inner layer structure on the upper and lower surfaces of the lens body. When nearsighted people wear their glasses for outdoor sports, the lens body may be scratched or bumped by tree branches or other hard objects. Due to the high hardness and strength of the first and second high-hardness inner layers, deformation of the lens body is effectively prevented. This improves the impact resistance, high hardness, and deformation prevention of the nearsightedness lens for outdoor sports.

[0016] 2. This utility model provides a first wear-resistant outer layer on the outer surface of a first high-hardness inner layer, and a second wear-resistant outer layer on the outer surface of a second high-hardness inner layer. During outdoor sports, nearsighted people wear glasses. This effectively prevents the inner and outer surfaces of the lens from directly rubbing against particles and gravel present in the outdoor environment. The high wear resistance of the first and second wear-resistant outer layers themselves further improves the overall wear resistance of the inner and outer surfaces of the glasses lens used for outdoor sports.

[0017] 3. This utility model symmetrically bonds a first side sleeve and a second side sleeve to the outer wall of the lens body. After the lens body is manufactured, it needs to be assembled into the mounting groove of the frame. During the snap-fit ​​assembly, it effectively avoids the phenomenon of abrasion between the lens body, which has weak abrasion resistance, and the frame, and effectively improves the abrasion resistance of outdoor sports myopia lenses when they are assembled into the frame.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 A wear-resistant, high-hardness spectacle lens includes a lens body 1, a first high-hardness inner layer 2 disposed on the upper end surface of the lens body 1, a first wear-resistant outer layer 21 disposed at the end of the first high-hardness inner layer 2 away from the lens body 1, a second high-hardness inner layer 3 disposed on the lower end surface of the lens body 1, a second wear-resistant outer layer 31 disposed at the end of the second high-hardness inner layer 3 away from the lens body 1, and a first side sleeve 4 and a second side sleeve 5 sleeved on the outer side of the lens body 1. Both the first side sleeve 4 and the second side sleeve 5 are provided with a main sleeve groove 6, and a secondary filling groove 7 is provided in the main sleeve groove 6. A main adhesive layer 61 is provided on the main sleeve groove 6, and a secondary adhesive layer 71 is provided in the secondary filling groove 7. The end face of the first side cover 4 is provided with a first adhesive layer 41, and the end face of the second side cover 5 is provided with a second adhesive layer 51. The lens body 1 is an outdoor sports lens with myopia correction, and is made of commonly used resin lenses.

[0022] It should be further explained that both the first high-hardness inner layer 2 and the second high-hardness inner layer 3 are silicon-based hardening film structures. The specific process for the silicon-based hardening film structure is as follows: the lens body 1 is cleaned by ultrasonic waves; then, the hardening impregnation solution is prepared, mainly containing a silane coupling agent, which is the main component for film formation. One end of the agent can react with the substrate of the lens body 1, and the other end can cross-link itself. The cleaned and dried lens body 1 is immersed in a tank containing the hardening solution. Then, the lens body 1 is vertically pulled out of the hardening solution at an extremely slow and constant speed. Due to the liquid... Due to the surface tension and the effect of the leveling agent, a uniform and flawless liquid film is formed on the surface of the lens body 1. Then, it is initially baked at a temperature of 80 degrees Celsius. The main purpose of this baking is to allow the solvent to evaporate slowly and to cause the molecules in the film to undergo initial hydrolysis and condensation reactions, forming a preliminary gel network. Then, the entire lens body 1 is transferred to an oven at a higher temperature for long-term heat treatment at 100 degrees Celsius. When the remaining solvent is completely removed, the silane molecules undergo a full condensation reaction, forming a dense and hard silicon-based hardened film three-dimensional network structure.

[0023] It should be further noted that both the first wear-resistant outer layer 21 and the second wear-resistant outer layer 31 are zirconium dioxide film structures. The specific process for constructing the zirconium dioxide film structure is as follows: First, the lens body 1 is cleaned to remove surface grease, dust, and ionic contaminants. Then, the lens body 1 is installed and fixed in a vacuum chamber, followed by evacuation. Next, a small amount of high-purity argon gas is introduced into the vacuum chamber, and a power source (usually an radio frequency power source) is applied to ionize the argon gas, generating argon plasma. Argon ions bombard the lens surface under the action of an electric field. This step significantly improves the adhesion of the zirconium dioxide film structure. Then, reactive magnetron sputtering is employed. The method involves introducing high-purity argon and high-purity oxygen into a vacuum chamber. Argon is the sputtering gas, and oxygen is the reactant gas. The oxygen flow rate needs to be precisely controlled to ensure the complete formation of stoichiometric zirconium dioxide. Next, a power source (DC or medium-frequency AC) is applied to the zirconium target. Under the confinement of a magnetic field, the argon is ionized to form a stable plasma glow. Then comes the sputtering process: argon ions are accelerated by an electric field and bombard the surface of the zirconium target, sputtering zirconium atoms / ions. At this time, the sputtered zirconium particles fly towards the surface of the lens body 1. During the flight and after reaching the surface of the lens body 1, they react chemically with the introduced oxygen to generate a zirconium dioxide film structure, which is then deposited on the lens body 1.

[0024] It should be further noted that both the first side sleeve 4 and the second side sleeve 5 are semi-ring-shaped structures. Both the first side sleeve 4 and the second side sleeve 5 are made of polycarbonate. Polycarbonate has excellent wear and impact resistance, which further improves the wear and impact resistance of the outer wall of the lens body.

[0025] It should be further noted that the front view of the main sleeve groove 6 is a U-shaped structure. The main adhesive layer 61 is evenly distributed along the inner wall of the main sleeve groove 6. Both the main adhesive layer 61 and the secondary adhesive layer 71 are made of epoxy resin, which has excellent bonding and fixing properties, and is waterproof and durable.

[0026] It should be further explained that the sub-filling groove 7 is a rectangular inner groove, and there are forty-nine sub-filling grooves arranged in a circle. The sub-adhesive layer 71 is filled in the sub-filling groove 7. The multiple sub-filling grooves 7 and the sub-adhesive layer 71 together further improve the stability of the first side sleeve 4 and the second side sleeve 5 on the outer wall of the lens body.

[0027] It should be further noted that the first adhesive layer 41 is uniformly coated along the end face of the first side sleeve 4, and the second adhesive layer 51 is uniformly coated along the end face of the second side sleeve 5. When both the first side sleeve 4 and the second side sleeve 5 are fitted onto the already manufactured lens body through the main sleeve groove 6 (see...), Figure 2 and Figure 5 When the lens body is composed of the spectacle lens body 1, the first high-hardness inner layer 2, the first wear-resistant outer layer 21, the second high-hardness inner layer 3, and the second wear-resistant outer layer 31 as described in this patent, the first adhesive layer 41 and the second adhesive layer 51 are both acrylic AB glue, which ensures the water resistance, weather resistance and temperature resistance of the splicing and bonding surface of the first side sleeve 4 and the second side sleeve 5.

[0028] Working principle: By setting a first high-hardness inner layer 2 and a second high-hardness inner layer 3 on the upper and lower end faces of the lens body 1 respectively, when nearsighted people wear their glasses for outdoor sports, the lens body 1 may be scratched or bumped by tree branches or hard objects outdoors. Due to the high hardness and strength of the first high-hardness inner layer 2 and the second high-hardness inner layer 3, the lens body 1 is effectively prevented from deforming, thereby improving the impact resistance, high hardness and deformation prevention of the nearsighted glasses lens for outdoor sports.

[0029] Furthermore, by setting a first wear-resistant outer layer 21 on the outer surface of the first high-hardness inner layer 2, and then setting a second wear-resistant outer layer 31 on the outer surface of the second high-hardness inner layer 3, when people with myopia wear glasses during outdoor sports, the friction between the inner and outer surfaces of the lens body 1 and the particles and gravel present in the outdoor environment is effectively avoided. The high wear resistance of the first wear-resistant outer layer 21 and the second wear-resistant outer layer 31 themselves further improves the wear resistance of the inner and outer surfaces of the glasses lens for outdoor sports.

[0030] In addition, by symmetrically bonding the first side sleeve 4 and the second side sleeve 5 to the outer side wall of the lens body 1, after the lens body is manufactured, it needs to be assembled into the mounting groove of the frame. During the snap-fit ​​assembly, the wear phenomenon between the lens body 1, which has weak wear resistance, and the frame is effectively avoided, thereby improving the wear resistance of the myopia lens for outdoor sports when it is assembled into the frame. The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
