Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a sleep-adjusting lens and glasses that provide clear vision. Background Technology

[0002] With the fast pace of modern life, sleep disorders are becoming increasingly common, leading to a growing demand for sleep aids among those suffering from insomnia. Traditional sleep aids (such as medications and physical noise reduction devices) suffer from high dependency and poor comfort, while optical technology has become a research hotspot due to its non-invasiveness and adjustability. Studies have shown that blue light (especially in the 440-500nm wavelength range) inhibits melatonin secretion and disrupts circadian rhythms. Sleep-regulating lenses adjust light waves (especially blue light) through the lens, thereby influencing a person's sleep state.

[0003] Most existing sleep-regulating lenses absorb blue light in the 440-500nm wavelength range. For example, invention patent CN202021204344 uses a light-absorbing film layer to directly absorb blue light in the 450-475nm range, reducing the impact of blue light from electronic devices at night. However, these lenses have low light transmittance (82%-85%), which can easily lead to a darker visual perception and color distortion, affecting daily use. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a sleep-regulating lens with clear vision. By setting an anti-reflective film layer on the inner surface of the substrate, the lens has a low reflectivity to light, allowing users to obtain better visual clarity and comfort. On the other hand, through the combination of the resin substrate and the light-regulating layer, the visible light waves can be adjusted, thereby selectively affecting the transmittance of blue light and controlling melatonin secretion to promote sleep. At the same time, it maintains a high transmittance for other visible light, maximizing the restoration of image clarity.

[0005] Specifically, the present invention adopts the following solution:

[0006] A clear vision sleep-adjusting lens includes a substrate. The side of the lens closest to the eyeglasses when worn is defined as the inner side. The inner surface of the substrate has an anti-reflective coating layer composed of sequentially stacked silicon oxide and titanium oxide layers, wherein the silicon oxide layer is connected to the inner surface of the substrate. The outer surface of the substrate has a light-adjusting layer composed of sequentially stacked silicon oxide and zirconium oxide layers, wherein the silicon oxide layer is connected to the outer surface of the substrate.

[0007] Furthermore, the substrate is a resin substrate.

[0008] Furthermore, the anti-reflective film layer comprises 7 layers, with the following thicknesses from the outside to the inside: the first layer is 100-300 nanometers, the second layer is 5-30 nanometers, the third layer is 20-60 nanometers, the fourth layer is 30-70 nanometers, the fifth layer is 5-30 nanometers, the sixth layer is 20-60 nanometers, and the seventh layer is 70-120 nanometers.

[0009] Furthermore, the thickness of the anti-reflective film layer from the outside to the inside is as follows: first layer 150-250 nanometers, second layer 10-25 nanometers, third layer 30-50 nanometers, fourth layer 40-60 nanometers, fifth layer 10-25 nanometers, sixth layer 30-50 nanometers, and seventh layer 80-110 nanometers.

[0011] Furthermore, the thickness of the light-modulating layer from the inside out is as follows: first layer 60-90 nanometers, second layer 10-18 nanometers, third layer 120-180 nanometers, fourth layer 120-180 nanometers, fifth layer 150-250 nanometers, sixth layer 10-25 nanometers, and seventh layer 120-180 nanometers.

[0012] Based on the same inventive concept, this utility model also provides eyeglasses, comprising a frame and lenses fixed to the frame, wherein the lenses are sleep-adjusting lenses for clear vision.

[0013] By adopting the aforementioned technical solution, compared with the prior art, this utility model can not only adjust sleep, but also provide clear vision, bright imaging effect, and better comfort when worn. Attached Figure Description

[0020] Example 1:

[0021] refer to Figure 1 A sleep-enhancing lens for improved visual clarity includes a substrate 1, an anti-reflective coating 3, and a light-adjusting layer 2. The side of the lens closest to the eyes when worn is defined as the inner surface; the anti-reflective coating 3 is located on the inner surface of the substrate 1, and the light-adjusting layer 2 is located on the outer surface of the substrate 1. This lens partially absorbs visible light through the substrate, adjusts the reflectivity of different light wavelengths through the light-adjusting layer, and combines this with the anti-reflective coating to adjust the reflectivity of light transmitted through the substrate, thereby promoting sleep and improving visual clarity.

[0022] Specifically, the substrate is a resin substrate. It is formed by injection molding a mixture of plastic pellets and pigments of different colors to create an injection-molded sheet with added pigments. This adjusts the transmittance of blue, green, yellow, and red in visible light. For example, 10,000 parts of plastic pellets, 0.5,000 parts of orange pigment, 0.6,000 parts of red pigment, 0.05,000 parts of black pigment, and 0.06,000 parts of blue pigment are added to a mixing tank and stirred evenly. The mixture is then placed in a dehumidifying oven at 120°C and baked for 3 hours. Finally, it is placed in an injection molding machine for injection molding, and then cleaned, hardened, and baked to obtain the substrate. The substrate has an average transmittance of ≤0.1% for light waves with wavelengths of 380-400nm, 15%-≤30% for light waves with wavelengths of 400-440nm, ≤10% for light waves with wavelengths of 440-510nm, and ≥80% for light waves with wavelengths of 510-780nm. Therefore, by selectively absorbing light waves with pigments in the substrate, different degrees of modulation can be achieved for short-wavelength blue light (wavelength 400-440nm) and long-wavelength blue light (wavelength 440-510nm).
