Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a photochromic lens with a refractive index of 1.50. Background Art

[0002] Lenses are made of optical materials such as glass or resin, and are transparent materials with one or more curved surfaces. After polishing, they are often assembled with eyeglass frames to correct the user's vision and obtain a clear field of vision. Photochromic lenses are specially treated in the lens coating process, such as using spiropyran compounds and high-speed spin coating on the lens surface. Depending on the intensity of light and ultraviolet rays, the molecular structure itself is reversed to open and close to achieve the effect of passing or blocking light.

[0003] When using traditional photochromic lenses, the edges of the lenses are fixed, which can easily cause the edges of the lenses to break, making the edges of the lenses sharp and easily causing scratches on the user's face during a collision.

[0004] Based on this, a photochromic lens with a refractive index of 1.50 and a protective rubber ring was designed. Utility Model Content

[0005] The utility model aims at the deficiencies in the prior art and provides the following technical solutions: a photochromic lens with a refractive index of 1.50, comprising a photochromic lens, an edge of the photochromic lens being sleeved with a rubber ring for protection, an edge of the photochromic lens being provided with a limiting groove, an inner side of the rubber ring being provided with a limiting convex ring adapted to the limiting groove, both sides of the rubber ring being integrally formed with edge guards wrapped around the upper and lower surfaces of the photochromic lens, an outer surface of the rubber ring being provided with a positioning groove for positioning, and a reinforcing component being provided inside the rubber ring.

[0006] As an improvement of the above technical solution, the reinforcement component includes a reinforcing steel ring arranged inside the rubber ring close to the outer ring, a nylon braided rope arranged inside the rubber ring, and an aluminum ring located in the middle, and the aluminum ring is located on the symmetry axis of the four nylon braided ropes.

[0007] As an improvement of the above technical solution, the nylon braided rope is formed by braiding and winding seven filaments.

[0008] As an improvement of the above technical solution, the reinforcing steel ring, nylon braided rope and aluminum ring are all annular structures.

[0009] As an improvement of the above technical solution, the photochromic lens includes a lens body and a photochromic coating disposed on both side surfaces of the lens body, and the outer surface of the photochromic coating is provided with a nano anti-fouling coating.

[0010] As an improvement of the above technical solution, a gap of 1 mm is provided between the limiting groove and the limiting convex ring, and the gap between the limiting groove and the limiting convex ring is filled with resin for bonding.

[0011] Beneficial effects of the utility model:

[0012] 1. The edge of the photochromic lens is protected by the rubber ring that is sleeved on the edge of the photochromic lens, thereby preventing the edge of the photochromic lens from breaking when the photochromic lens is directly installed on the eyeglass frame. The limiting convex ring arranged on the inner side of the rubber ring and the limiting groove opened on the edge of the photochromic lens, when the rubber ring is sleeved on the edge of the photochromic lens, the limiting groove and the limiting convex ring are adapted, thereby increasing the stability of the rubber ring sleeved on the edge of the photochromic lens. At the same time, the integrally formed edge guards on both sides of the rubber ring are wrapped around the upper and lower surfaces of the photochromic lens, thereby improving the stability of the rubber ring wrapped around the outside of the photochromic lens. The reinforcing component arranged in the rubber ring increases the strength of the rubber ring, thereby avoiding the problem of the photochromic lens falling off due to the breakage of the rubber ring after being damaged, thereby improving the stability of the photochromic lens installation.

[0013] 2. Through the reinforcement assembly composed of a reinforcing steel ring, a nylon braided rope and an aluminum ring, the reinforcing steel ring is located inside the outer ring of the rubber ring, the nylon braided rope and the aluminum ring are located inside the rubber ring, and the aluminum ring is located on the symmetry axis of the four nylon braided ropes, so that the reinforcing steel ring reinforces the outer ring of the rubber ring, and the nylon braided rope and the aluminum ring cooperate to reinforce the inner ring of the rubber ring, thereby improving the strength of the rubber ring structure.

[0014] 3. The photochromic lens is composed of a lens body, a photochromic coating and a nano anti-fouling coating, and the photochromic coating is arranged on the two side surfaces of the lens body, so that the photochromic lens has a color-changing function through the photochromic coating, and the photochromic lens has an anti-oil function through the nano anti-fouling coating, thereby improving the cleanliness of the photochromic lens surface.
