Description

Technical Field

[0001] This utility model belongs to the field of spectacle lens technology, and relates to a spectacle lens with an anti-glare and anti-reflective film. Background Technology

[0002] Eyeglass lenses are an important component of eyeglasses. They are optical lenses used to correct vision defects or protect the eyes, and are usually made of transparent materials such as glass and resin. Eyeglass lenses are widely used, and in the welding industry, welding protective covers are mainly made of eyeglass lenses. However, existing eyeglass lenses do not have an anti-glare effect during long periods of time, which can easily cause dizziness when looking at the welding screen for a long time. To address this issue, we have designed an eyeglass lens with an anti-glare and anti-reflective film to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this invention is to provide an eyeglass lens with an anti-glare and anti-reflective film to solve the problems mentioned in the background art.

[0004] The purpose of this utility model can be achieved through the following technical solution: a spectacle lens with an anti-glare and anti-reflective film, comprising an outer frame, a glass lens fixedly disposed inside the outer frame, an AR blue film attached to the top of the glass lens, and an anti-oil film attached to the surface of the AR blue film.

[0005] In the above-mentioned eyeglass lens with anti-glare and anti-reflective film, an annular groove is formed on the outer edge of the anti-oil film, and an annular pressure strip is fixedly provided at the top of the inner part of the outer frame. The annular pressure strip and the annular groove are pressed together and fixed.

[0006] In the aforementioned spectacle lens with an anti-glare and anti-reflective film, the outer edge of the glass lens is provided with multiple threaded holes at equal intervals, and the outer frame is provided with multiple circular grooves at equal intervals. Each of the multiple circular grooves is threaded with a locking bolt, and the locking bolt is threadedly connected to the threaded hole.

[0007] In the aforementioned spectacle lens with an anti-glare and anti-reflective coating, the thickness of the glass lens is 20-50 mm.

[0008] In the aforementioned eyeglass lens with an anti-glare and anti-reflective coating, the thickness of the AR blue film is 20-30 nanometers, and the light transmittance of the AR blue film is greater than 90%.

[0009] In the aforementioned type of eyeglass lens with an anti-glare and anti-reflective film, the anti-oil film is made of TPU material.

[0010] Compared with the prior art, the advantages of the eyeglass lens with anti-glare and anti-reflective film of this utility model are: by setting AR blue film and anti-oil film on the surface of the glass lens, the eyeglass lens has a better anti-glare and anti-reflection effect, which effectively improves the comfort of the wearer and makes the field of vision clearer.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1-3 As shown, the present invention provides an eyeglass lens with an anti-glare and anti-reflective film, comprising an outer frame 1, a glass lens 3 fixedly disposed inside the outer frame 1, an AR blue film 4 attached to the top of the glass lens 3, and an anti-oil film 5 attached to the surface of the AR blue film 4.

[0017] Specifically, by combining an AR blue film 4 and an anti-oil film 5 on the surface of the glass lens 3, the eyeglass lens has a better anti-glare and reflection reduction effect, effectively improving the wearer's comfort.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a spectacle lens with an anti-glare and anti-reflective film. The outer edge of the anti-oil film 5 is provided with an annular groove 7, and the top of the inner frame 1 is fixed with an annular strip 6. The annular strip 6 and the annular groove 7 are pressed together and fixed.

[0019] Specifically, the combination of the annular pressure strip 6 and the annular pressure groove 7 can press the edge of the lens firmly, preventing the AR blue film 4 and the anti-oil film 5 from bulging out and affecting their service life.

[0020] Multiple threaded holes 8 are equidistantly provided on the outer edge of the glass lens 3, and multiple circular grooves are equidistantly provided on the edge of the outer frame 1. Locking bolts 2 are threadedly connected inside the multiple circular grooves, and the locking bolts 2 are threadedly connected to the threaded holes 8.

[0021] Specifically, the locking bolt 2 is threaded into the threaded hole 8 to secure the lens inside the outer frame 1.

[0022] The thickness of glass lens 3 is 20-50mm.

[0023] AR Blue Film 4 has a thickness of 20-30 nanometers and a light transmittance of over 90%.

[0024] The oil-resistant membrane 5 is made of TPU material.

[0025] In practice, when using this eyeglass lens, by combining an AR blue film 4 and an anti-oil and stain film 5 on the surface of the glass lens 3, the eyeglass lens has a better anti-glare and reflection reduction effect, which effectively improves the comfort of the wearer.
