Description

Technical Field

[0001] The utility model relates to the technical field of myopia lenses, in particular to a pair of self-adaptive myopia prevention and control glasses. Background Art

[0002] Myopia is a refractive state in which parallel light rays are refracted through the eye's refractive system and focus on the retina, so myopic eyes cannot see distant targets clearly. In recent years, with the rapid development of electronic information technology, the load of close-range eye use has increased, and the incidence of myopia has become increasingly high, especially for adolescents and children. How to prevent and control myopia has attracted more and more attention.

[0003] At present, a generally recognized theory of myopia prevention and control is the optical defocus theory, which holds that if the image is focused in front of the retina (i.e., positive defocus), the eye axis is not easy to grow, and myopia is controlled; applying an image focused behind the retina (negative defocus) has the opposite effect. The mainstream myopia prevention and control lenses are defocus lenses, which use the principle of myopia defocus to correct the central refractive error while using the peripheral relative positive power to correct the hyperopic defocus of the peripheral retina of the myopic eye, thereby inhibiting the eye axis growth and myopia progression induced by the hyperopic defocus of the peripheral retina, so as to delay the worsening of vision. However, the defocus of traditional defocus lenses is fixed and cannot be adjusted according to the user's real-time eye status. Moreover, the effect of traditional defocus lenses will continue to decline with the use time, resulting in poor user wearing experience and comfort. Utility Model Content

[0030] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] like Figure 1 As shown, this embodiment provides an adaptively adjustable myopia prevention and control glasses, including lenses and frames, wherein the lenses include a protective layer 1, a light-transmitting adjustment layer 2, a blue light filtering layer 3, an adjustment layer 4, a collection layer 5, and an optical substrate layer 6 arranged from front to back; the sensor 51 of the collection layer 5 and the actuator of the adjustment layer 4 can be connected to the microprocessor integrated in the frame by signal, and the actuator can dynamically adjust the defocus and light scattering effects of the adjustment layer 4. In this specific embodiment, the sensor 51 is a micro sensor, and the micro sensor includes but is not limited to a retinal activity detector, a pupil dilation detector, a light sensor, an infrared sensor, and an ultraviolet sensor.

[0032] Specifically, the protective layer 1 is made of special materials and is surface hardened, which can effectively resist scratches. At the same time, a super-hydrophobic coating is added to enhance the self-cleaning function. The light-transmitting adjustment layer 2 uses optical color change technology to automatically adjust the lens transmittance according to the ambient light intensity. The blue light filter layer 3 uses special materials, which can effectively absorb and reflect high-energy blue light to protect the eyes. The user's eye data and environmental data are continuously collected through the sensor 51 in the lens. This includes the current light intensity, ultraviolet level, eye health data, etc., and the data is sent to the microprocessor for analysis to determine the appropriate adjustment plan; the microprocessor's signal indicates that the actuator dynamically adjusts the defocus and light scattering effects of the adjustment layer 4 to better fit the user's eye situation. Compared with the prior art, not only the user's wearing experience and comfort are higher, but also the scope of application of the lens can be improved by adjusting the defocus and light scattering effects, thereby improving the service life of the lens. The optical substrate layer 6 uses a highly transparent, lightweight, impact-resistant optical substrate to ensure the basic optical properties and strength of the lens. Through high-precision integrated production technology, the close integration of each layer is ensured, avoiding inter-layer reflection and other problems that may affect the visual effect.

[0033] Furthermore, if Figure 3 As shown, the sensor 51 can be embedded in the edge of the collection layer 5. For example, the light sensor and the ultraviolet sensor can be set at the top edge of the lens, so that the ambient light can be sensed most directly. The microprocessor is the "brain" of the lens and needs to be protected in a relatively stable environment, so the microprocessor is set inside the frame and sufficient space is reserved for heat dissipation and protection.

[0034] Furthermore, if Figure 1 and Figure 2 As shown, the adjustment layer 4 includes a first adjustment layer 41 and a second adjustment layer 42; the actuator includes a first actuator and a second actuator; the first actuator is integrated in the first adjustment layer 41, and the first adjustment layer 41 is used to adjust the defocus effect; the second actuator is integrated in the second adjustment layer 42, and the second adjustment layer 42 is used to adjust the light scattering effect. Specifically, the first adjustment layer 41 includes a first packaging film 411, a second packaging film 412 and a first liquid crystal layer 413; the first liquid crystal layer 413 is arranged between the first packaging film 411 and the second packaging film 412, and the first actuator is integrated in the first packaging film 411. The second adjustment layer 42 includes a third packaging film 421 and a second liquid crystal layer 422; the second liquid crystal layer 422 is arranged between the second packaging film 412 and the third packaging film 421, and the second actuator is integrated in the third packaging film 421. Therefore, the electric fields of the first liquid crystal layer 413 and the second liquid crystal layer 422 are adjusted respectively by the first actuator and the second actuator, thereby changing their refractive indices, and realizing dynamic adjustment of defocus and light scattering respectively.

[0035] Furthermore, in this specific embodiment, the outer surface of the optical substrate layer 6 is a first curved surface facing the eye, and the outer surface of the protective layer 1 is a second curved surface facing away from the eye; a clear vision area and a light diffusion area surrounding the clear vision area are provided on the first curved surface, and a defocus area 7 formed by a microlens array is provided on the second curved surface.

[0036] In this specific embodiment, a gyroscope and an accelerometer are also integrated on the frame; the gyroscope and the accelerometer are connected to a microprocessor to capture the movement status of the user's head and body in real time.

[0037] Furthermore, its specific working conditions are as follows: data collection: First, the micro sensors in the lenses continuously collect the user's eye data and environmental data, including the current light intensity, ultraviolet light level, eye health data fed back by infrared sensors, and other data.

[0038] Data Analysis: The collected data is then immediately fed into the lens’ built-in microprocessor for analysis. The algorithm in the microprocessor analyzes the data based on the user’s visual needs and environmental conditions to determine the appropriate lens adjustment plan.

[0039] Execute adjustments: Based on the instructions of the microprocessor, the micro-actuators in the lens will make the necessary adjustments at the fastest speed. This can include changing the transmittance of the light-transmitting layer, adjusting the refractive index of the defocus and scattering of the adjustment layer 4, or adjusting the absorption rate of the blue light filter layer 3, etc.

[0040] Continuous optimization: The above process is not completed once, but will continue. The sensor 51 and the actuator will continue to work together to keep the lens in the state that best suits the user and the environment. In addition, the algorithm in the microprocessor will continue to learn and optimize, making it more efficient when handling the same or similar situations, and better meet the individual needs of users.
