Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a low-reflection, high-transmittance color-enhancing lens and eyeglasses. Background Technology

[0002] During outdoor sports, glasses may slip or vibrate due to inertia, causing the optical center to misalign with the pupil. A misalignment exceeding 2mm can result in significant visual blurring. Similar issues occur during skiing, cycling, and other activities. To address these problems, chromatic amplification lenses, through special lens design, adjust the contrast between different colors, providing users with sufficiently precise and clear visual support. This is particularly useful for distinguishing snow undulations while skiing, tracking the ball's trajectory in golf, and spotting obstacles while cycling.

[0003] Currently, by adjusting the transmittance of different light bands, the contrast between different colors can be adjusted. However, this can easily cause light reflection within the lens. The stray light generated by the inner layer reflection can create artifacts such as ghosting and halos, resulting in a poor user experience. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a low-reflection, high-transmittance color-enhancing lens and glasses. By attaching an anti-reflective film layer to at least one surface of the substrate, the average reflectivity of the substrate for visible light wavelengths of 380-780nm is reduced to ≤1%, thereby decreasing internal reflection within the substrate. This allows the lens to perfectly adapt to different light wavelengths of visible light in the 380-780nm range, providing a clear and comfortable visual experience.

[0005] To solve this technical problem, the present invention adopts the following solution:

[0006] A low-reflection, high-transmittance color-enhancing lens includes a substrate, wherein at least one surface of the substrate is connected to an anti-reflective coating layer, the anti-reflective coating layer comprising nine layers, wherein SiO2 layers and H4 layers are alternately stacked from the closest to the substrate outwards, with thicknesses of 1000-3000 Å, 50-300 Å, 100-500 Å, 100-500 Å, 100-500 Å, 100-500 Å, 100-3000 Å, and 500-1200 Å, respectively.

[0007] Furthermore, both sides of the substrate are connected to an anti-reflective film layer.

[0008] Furthermore, the antireflective coating layers located on both sides of the substrate have a symmetrical structure with the plane of the substrate as the axis.

[0009] Furthermore, the thickness of the anti-reflective coating layer, from the closest point to the substrate outwards, is successively 1500-2500 Å, 100-250 Å, 200-300 Å, 1500-2500 Å, 200-400 Å, 200-400 Å, 200-400 Å, and 200-400 Å. Further, the thickness of the anti-reflective coating layer, from the closest point to the substrate outwards, is successively 2000 Å, 200 Å, 300 Å, 2000 Å, 300 Å, 300 Å, 300 Å, 2000 Å, and 800 Å.

[0010] Furthermore, the substrate is a pigment sheet.

[0011] Based on the same inventive concept, this utility model also provides eyeglasses, including the aforementioned low-reflection, high-transmittance color-enhancing lens.

[0012] By adopting the aforementioned technical solution, this utility model has the following advantages compared with the prior art:

[0013] (1) By attaching an anti-reflective film layer to the surface of the substrate, the average reflectivity of visible light waves of 380-780nm is ≤1%, which can solve the internal reflection problem of the lens and improve the visual clarity.

[0014] (2) Preferably, the substrate uses a color powder sheet to adjust the transmittance of different light waves. When combined with the anti-reflective film layer, it can improve the imaging effect of objects in motion, making it easier for users to identify the outline of objects in motion, distinguish the undulations of snow when skiing, and track the trajectory of the ball in golf.

[0027] Anti-reflective coatings 2 are attached to both sides of the substrate 1, and the anti-reflective coatings 2 on both sides are symmetrical about the plane on which the substrate 1 is located. This embodiment, based on Embodiment 1, deposits anti-reflective coatings on both sides of the substrate, resulting in better improvement of the clarity of the edge contours of objects operating at high speeds.
