Description

Technical Field

[0001] The invention relates to the technical field of ophthalmic optometry equipment, and in particular to a pair of highly selective filtering glasses. Background Art

[0002] With the change of eye-use environment, the problem of myopia in children has become increasingly prominent. In terms of myopia prevention and control, it is recommended that children spend at least 2-3 hours of outdoor activities every day to allow their eyes to be fully exposed to natural light; in addition, it is necessary to control the time of eye use, avoid long-term close-up use of the eyes, maintain correct reading and writing posture, ensure sufficient and soft light, and reduce the use of electronic products. In terms of treatment, for children who already have myopia, they should choose appropriate glasses or orthokeratology lenses for correction, and even need to use eye drops or oral specific medication intervention; but the effect of myopia treatment is poor, mainly because of poor wearing comfort or long daily time required, resulting in poor compliance, which makes it difficult to effectively prevent and control the development of myopia.

[0003] At present, researchers have studied the effects of light environment on myopia through a variety of animal models, thus providing a scientific basis for the optical control of myopia in children. For example, Ying-Yi Chen et al. found that in some animal experiments, such as tree shrews and rhesus monkeys, red light was observed to inhibit myopia. For example, long-wavelength (red) light can cause hyperopia in young and adolescent tree shrews, and narrow-band long-wavelength lighting can promote hyperopia and delay the development of myopia in infant rhesus monkeys. At the same time, clinical studies have shown that repeated low-intensity red light (RLRL) therapy has shown a certain effect in slowing the progression of myopia in children, as shown by the reduction of refractive error and axial length change. Youssef MA et al. reviewed the effects of RLRL therapy on myopia in children, showing the effectiveness of 650nm RLRL red light in controlling myopia in short-term follow-ups of 3, 6 and 12 months, and showed positive effects in axial length AL, equivalent spherical diopter SER and subfoveal choroidal thickness SFCT.

[0004] Based on the effect of red light on myopia prevention and control, there are light-feeding devices on the market. They stimulate the fundus through light irradiation of a specific wavelength, usually 650nm red light, and improve the microcirculation of the fundus, prompting the retina to release a large amount of dopamine, improving the axial length and refractive power of the eye, thereby achieving the purpose of preventing and controlling myopia. However, with the use of light-feeding devices, safety issues of the products have also been exposed, because they may cause retinal damage, so there is some controversy about their safety.

[0005] In addition, studies have shown that ultraviolet glasses (360-400nm) have an inhibitory effect on the growth of the eye axis and the development of myopia in myopic children. Ultraviolet light maintains choroidal thickness through the OPN5 photoreceptors in the retina and activates the EGR1 gene, thereby inhibiting the growth of the eye axis. Animal experiments have shown that ultraviolet light exposure can reduce the development of deprivation myopia. At the same time, there is more ultraviolet light in the outdoor environment, and traditional glasses will block ultraviolet light. Therefore, ultraviolet glasses are designed to supplement this band to slow down the development of myopia.

[0006] If we can use natural light sources more efficiently and at the same time improve the efficiency of prevention and treatment, shortening the daily 2-3 hours of outdoor activities to half an hour or even shorter, then the prevention and control of myopia will be easier to achieve, and it will also be safer and more environmentally friendly. Summary of the invention

[0007] The present invention provides a highly selective filtering glasses, which have high transmittance in certain specific bands of light and lower transmittance in certain bands, thereby increasing the proportion of effective prevention and control bands. The glasses filter improves the utilization efficiency of natural light, so that the beneficial effect of myopia prevention and control brought about by 2 hours of outdoor activities can be achieved in a shorter time. This not only provides a safe myopia prevention and control device, but also solves the problem of harsh conditions for using natural light to prevent and control myopia.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions: A highly selective filter spectacles, the filter spectacles comprising the following optical transmission characteristics: The first light transmission wavelength range is 360nm to 425nm; The second light transmission wavelength range is 600nm to 680nm; All wavelengths within the wavelength range of 360 nm to 800 nm except the first and / or second light transmission wavelength range are the light attenuation wavelength range; Among them, the light transmittance of the first transmission wavelength range and the second transmission wavelength range is 60% to 99.999%; the light transmittance of the light attenuation wavelength range is 10% to 75%; and the light transmittance of the first and second transmission wavelength ranges is greater than the light transmittance of the light attenuation wavelength range.

[0009] Furthermore, the first light transmission wavelength range and the second light transmission wavelength range together constitute a light transmission wavelength range, and 425nm to 600nm and 680nm to 800nm ​​are light attenuation wavelength ranges; wherein the ratio of the light transmittance of the light transmission wavelength range to the light transmittance of the light attenuation wavelength range is (9.99:1) to (1.31:1); the light transmittance of the light transmission wavelength range is 80-99.999%; and the light transmittance of the light attenuation wavelength range is 10-75%.

[0011] Furthermore, the light transmission wavelength range is 600nm to 680nm, and the light attenuation wavelength range is 360nm to 600nm and 680nm to 800nm.

[0012] Furthermore, the lenses of the filter glasses are formed by coating, and the film layer includes a low refractive index film layer located on the upper surface of the substrate and a high-low refractive index composite film layer located on the lower surface of the substrate.

[0013] Furthermore, the low refractive index film layer is formed by alternately depositing magnesium fluoride and silicon dioxide; the high-low refractive index composite film layer is composed of two film systems, namely a titanium dioxide and magnesium fluoride film system and a zinc oxide and silicon dioxide film system.

[0014] Furthermore, the low refractive index film layer has 38 layers with a total thickness of 1 μm to 3 μm; the titanium dioxide and magnesium fluoride film system has 84 layers with a total thickness of 1.5 μm to 2 μm; the zinc oxide and silicon dioxide film system has 48 layers with a total thickness of 0.6 μm to 0.98 μm.

[0016] Furthermore, the lenses of the filter glasses are formed by alternately depositing aluminum oxide and silicon dioxide, with a total of 52 layers and a total film thickness of 2 μm to 5.2 μm.

[0017] Furthermore, the lenses of the filter glasses are formed by alternately depositing aluminum oxide and silicon dioxide, with a total of 64 layers and a total film thickness of 5 μm to 8.2 μm.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The present invention controls the light transmittance of the eyeglass filter to increase the light transmittance in a specific violet or red wavelength range, while attenuating the light transmittance in the remaining wavelength ranges, thereby filtering and optimizing the wavelengths of natural light, thereby effectively inhibiting the excessive growth of the eye axis and delaying the development of myopia. Compared with the light-feeding instrument, the present invention is safer and has no obstacles in use, and can be worn during outdoor activities. The present invention controls the ratio of the light transmittance of the light transmission wavelength range and the light attenuation wavelength range, so that the light transmission wavelength range has a higher proportion, thereby optimizing the prevention and control effect of myopia; The present invention fully increases the "utilization efficiency" of light through the eyeglass filter, and only needs to be worn for about 30 minutes a day to achieve the prevention and control effect, which is easier to achieve than outdoor activities for more than 2-3 hours a day; The eyeglass filter of the present invention not only has a controlling effect on the development of myopia, but also has an effect on users who already have insufficient hyperopia reserve or are close to emmetropia, and can help them prevent the premature occurrence of myopia.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] For children, it is necessary not only to pay attention to the control of myopia, but also to pay attention to the prevention of myopia. During the period of childhood and adolescence, the eyeball and vision are in a stage of gradual development and maturation. With growth and development, the eyeball gradually grows larger, the eye axis becomes longer, and the physiological hyperopia gradually decreases, thus tending to emmetropia. After emmetropia, if the eyeball continues to grow and the eyeball is too long, it will develop into myopia. In addition to affecting daily life and study, premature myopia can easily develop into high myopia if it is not controlled. High myopia is irreversible. As the eye axis continues to lengthen, the retina will slowly become thinner or even torn, leading to ischemia of the fundus, thereby causing a variety of serious eye problems such as retinopathy and macular degeneration.

[0022] Repeated low-intensity red light RLRL therapy can effectively inhibit the growth of the eye axis, thereby achieving the purpose of treating and preventing myopia. The possible reason is based on the regulation of ipRGCs-related neurotransmitters. Ai-Lin Liu et al. studied the mechanism of action of ipRGCs in eye growth and myopia development. The results showed that it regulates the axial length (AL) of the eye and the radius of corneal curvature (CRC) through melanopsin signals and rod / cone drive signals, respectively, to achieve the effect of myopia prevention and control.

[0023] Based on single-vision glasses, the present invention selects the wavelength of light by coating the glasses lenses. When worn during outdoor activities, light of a specific wavelength band in natural light enters the eye through the glasses lenses, thereby improving the efficiency of myopia prevention and treatment, so that the effect of the original 2-hour outdoor activity can be achieved in a shorter time (such as half an hour). To achieve the above effect, it is necessary to determine the appropriate wavelength band. Although existing studies have shown that light with a wavelength of 650nm has a good effect, when it is applied to glasses lenses, only this wavelength cannot be retained. Usually, a certain wavelength with high transmittance is retained; but wavelengths of other bands cannot be completely cut off. Completely cutting off will affect vision and thus affect the development of normal outdoor activities.

[0024] In the selection of eyeglass lens materials, the commonly used materials are optical glass, polycarbonate, polyallyl diglycol carbonate, and polymethyl methacrylate.

[0025] Optical glass has a high refractive index and high stability and is a commonly used material for eyeglass lenses. Polycarbonate is a thermoplastic that is widely used in eyeglass lenses. It has extremely high impact resistance and is lightweight, which can improve wearing comfort. It is a commonly used material for children's glasses. Polyallyl diglycol carbonate CR-39 has unique optical performance advantages. It has good optical transparency and a relatively low dispersion coefficient, which can effectively reduce dispersion and avoid chromatic aberration in imaging. Currently, the application of CR-39 in eyeglass lenses is gradually gaining favor and is often used to manufacture high-quality aspheric lenses. Polymethyl methacrylate has the characteristics of easy processing and good optical uniformity, and is widely used in the primary processing of eyeglass lenses.

[0026] In the selection of filter film materials, metal oxides such as titanium dioxide TiO2, zirconium dioxide ZrO2, silicon dioxide SiO2, etc. are commonly used materials. Titanium dioxide has a moderate refractive index in the visible light band, and its crystal structure makes the film dense and can increase the mechanical strength and chemical stability of the film; while zirconium dioxide has the characteristics of high refractive index. In the design of multi-layer film systems, it can accurately adjust the interference effect of light in different bands, which helps to achieve complex transmittance control goals. In addition, magnesium fluoride MgF2 is also an important choice. It has low absorption and low scattering of light in specific bands. When constructing the anti-reflection film structure, its low refractive index, combined with high refractive index materials, can effectively reduce cross-sectional reflection and improve the transmittance of light in a specific band.

[0027] The laws of interference, refraction and reflection of light are the cornerstones of optical coating design. During the coating process, by precisely controlling the thickness of the film layer, optical fibers of a specific wavelength are made to interfere with each other after being reflected at the upper and lower interfaces of the film layer, thereby achieving the effect of enhancing or weakening the intensity of the transmitted light. In addition, it is necessary to consider the change in the propagation path caused by the refraction of light between the film layers to accurately calculate the optical path difference and ensure constructive interference in the target band. By making the phase difference of the reflected light at the upper and lower interfaces of the film layer meet specific conditions, the reflected light is caused to cancel each other out, thereby reducing the reflectivity of the lens surface and improving the light transmission performance. In summary, multilayer film systems are usually constructed by alternately coating high and low refractive index film layers, and using multiple reflections and interferences of light between different film layers to construct a film system structure with specific spectral response characteristics. For periodic multilayer film systems, their reflectivity (R) and transmittance (T) can be accurately calculated by the characteristic matrix method. This method can accurately predict the optical performance of the film system at different wavelengths by constructing the characteristic matrix of each film layer and recursively solving it according to the boundary conditions, providing theoretical support for film layer design. Example 1

[0028] The filter glasses of this embodiment refer to frame glasses whose lenses are filter lenses. The filter lenses are made of CR-39 as a base material and a filter film is plated on the top of the CR-39.

[0029] The coating process is as follows: Pre-treatment: Place the CR-39 substrate in an ultrasonic cleaning machine, add deionized water and a neutral detergent for cleaning, adjust the ultrasonic power to 100-150W, and clean for 15-20 minutes; take out the lens and place it in an oven to dry at 60-70°C.

[0030] Coating: Upper surface coating: Install the dried lens on the sample rack of the vacuum coating machine, turn on the vacuum system, and pump the vacuum degree in the coating chamber to 5×10 -5 Pa or less; start heating to preheat the lens to 150-200°C; start the electron beam evaporation source to evaporate the magnesium fluoride material, and deposit the magnesium fluoride film at a rate of 0.05-0.1nm / s. When the predetermined thickness is reached, evaporate the silicon dioxide material, and deposit the silicon dioxide film at a rate of 0.16-0.12nm / s to a predetermined thickness; repeat the above process until the predetermined number of film layers C1 is reached; Lower surface coating: turn on the ion source to generate an ion beam with an energy of 500-800eV, bombard the lens for 5-8 minutes; evaporate titanium dioxide material through electron beam, deposit titanium dioxide film at a rate of 0.03-0.06nm / s until the predetermined thickness is reached; evaporate magnesium fluoride material, deposit magnesium fluoride film at a rate of 0.05-0.1nm / s until the predetermined thickness is reached; repeat the above process until the predetermined number of film layers C2 is reached.

[0034] The thickness of each layer in the C2 film system is shown in Table 2: Table 2

[0035] The thickness of each layer in the C3 film system is shown in Table 3: Table 3

[0036] Post-processing: After the coating is completed, keep the vacuum stable and cool it naturally to room temperature, slowly introduce high-purity nitrogen to normal pressure, and take out the coated lens. Test the transmittance with a spectrophotometer. The test results are as follows Figure 1 As shown. It is estimated that the transmittance ratio in the wavelength ranges of 360 (inclusive)-425nm, 425 (inclusive)-600nm, 600 (inclusive)-680nm, and 680 (inclusive)-800nm ​​is 6:3.3:6.5:1.

[0037] In the above process, the thickness of each layer is monitored by a quartz crystal sensor when coating using a Semicore 1200 vacuum coating machine. Example 2

[0038] This embodiment uses the same substrate as the embodiment 1 and the same pre-treatment process, and the difference lies in the coating and post-treatment process. This embodiment obtains a coated lens with a single anti-reflection 360 (inclusive) -425nm band.

[0039] In this embodiment, a film is coated on one side of the substrate: the dried lens is mounted on the sample rack of the vacuum coating machine, the vacuum system is turned on, and the vacuum degree in the coating chamber is pumped to 5×10 -5 Pa or less; turn on the heating to preheat the lens to 200°C; turn on the ion source to generate Ar with an energy of 5000eV + The ion beam bombards the lens for 5-8 minutes; the electron beam evaporation source is started to evaporate the aluminum oxide material and deposit the aluminum oxide film at a rate of 0.12nm / s. When the predetermined thickness is reached, the silicon dioxide material is evaporated and the silicon dioxide film is deposited at a rate of 0.18nm / s to a predetermined thickness; the above process is repeated until the predetermined number of film layers C4 is reached.

The thickness of each layer in the C4 film system is shown in Table 4.

[0041] Table 4

[0042] Post-treatment: After nitrogen is introduced, annealing is carried out at 300°C for 1 hour under the protection of nitrogen atmosphere, and then cooled to room temperature in the furnace.

[0043] The transmittance test results in this embodiment are as follows Figure 2 As shown, it has high transmittance in the 360-425nm band, and the transmittance range is approximately in the range of 82-99.8%; the light transmittance is suppressed in the 425-800nm ​​band, meeting the expected design goals. Example 3

[0044] This embodiment uses the same substrate as that of embodiment 1 and adopts the same pre-treatment and post-treatment processes. The difference lies in the coating process. This embodiment obtains a coated lens with a single anti-reflection wavelength band of 600 (inclusive) -680nm.

[0045] In this embodiment, a film is coated on one side of the substrate: the dried lens is mounted on the sample rack of the vacuum coating machine, the vacuum system is turned on, and the vacuum degree in the coating chamber is pumped to 5×10 -5 Pa; turn on the heating to preheat the lens to 220°C; turn on the ion source to generate Ar with an energy of 450eV + The ion beam bombards the lens for 5-8 minutes; the electron beam evaporation source is started to evaporate the aluminum oxide material and deposit the aluminum oxide film at a rate of 0.15nm / s. When the predetermined thickness is reached, the silicon dioxide material is evaporated and the silicon dioxide film is deposited at a rate of 0.20nm / s to a predetermined thickness; the above process is repeated until the predetermined number of film layers C5 is reached.

[0046] In the above process, the film system on the upper surface is the base {[H3L2]^S5} vacuum, where H3 is aluminum oxide, L2 is silicon dioxide, S4 is the fifth period number, the number of film layers C5 is 64, and the total thickness of the C5 film layer is about 8.2μm. The thickness of each layer in the C5 film system is shown in Table 5.

[0047] Table 5

[0048] Post-treatment: After nitrogen is introduced, annealing is carried out at 350°C for 2 h under nitrogen atmosphere protection, and then the temperature is gradually reduced (10°C / min) to room temperature.

[0049] The transmittance test results in this embodiment are as follows Figure 3 As shown, it has high transmittance in the band of 600-680nm, and the transmittance range is approximately in the range of 85-99.8%; the light transmittance in the remaining bands within the range of 360-800nm ​​is suppressed, meeting the expected design goals.

[0050] The following test examples were all conducted using the method of daily wearing for 30 minutes.
