Description

Technical Field

[0001] This utility model relates to the field of myopia prevention and control technology, and further to an eyeglass structure and wearable device for myopia improvement. Background Technology

[0002] Studies have shown a strong correlation between rising myopia rates and unhealthy eye habits, such as prolonged viewing of close-up objects, extended use of electronic devices like mobile phones, televisions, and computers, and a lack of outdoor activities. Prolonged viewing of close-up objects weakens the lens's accommodative ability, accelerating the growth of the eye axis and leading to myopia. Prolonged use of electronic devices and a lack of outdoor activity deprive the eyes of specific wavelengths of light, potentially reducing choroidal blood flow and causing abnormal eye axis growth.

[0003] Currently, in addition to maintaining correct eye habits, myopia prevention and control in clinical practice employs various treatment methods, including wearing peripheral defocus glasses and using specific wavelengths of light for fundus irradiation. In optical interventions, the selection of spectral characteristics has a significant impact on efficacy, with the precise selection of the treatment wavelength being particularly crucial. Furthermore, clinical practice shows that single intervention measures often fall short of achieving ideal prevention and control results.

[0004] Therefore, it is necessary to design an eyeglass structure and wearable device for myopia improvement to solve the above problems. Utility Model Content

[0046] In one embodiment, refer to the appendix to the specification. Figure 1 , Figure 2 The present invention provides a glasses structure for improving myopia, comprising: a lens 1, a frame 2, and an LED light assembly 3. The lens 1 includes a structural part 11 and a non-structural part 12, the non-structural part 12 being disposed in the middle of the structural part 11, and a lens array 13 being disposed on the structural part 11. The frame 2 is disposed around the lens 1, and an optical reflective layer is disposed on the frame 2 near the lens 1. The LED light assembly 3 is disposed between the lens 1 and the frame 2, and the LED light assembly 3 is used to emit light of at least two wavelengths.

[0047] In this embodiment, the non-structural part 12 can be the lens body or a hollow lens structure. The non-structural part 12 is located at the center of the pupil of the human eye.

Alternatively, the blue light has a peak wavelength of 475nm and a WWHM of 15nm, and the red light has a peak wavelength of 650nm and a WWHM of 15nm. Of course, the specific values ​​of the peak wavelength and WWHM can also be set to other values.

[0055] In one embodiment, reference is made to the appendix to the specification. Figures 5 to 9 Lens 1 is a planar lens with dimensions w = 3cm, l = 4cm, and a thickness of 4mm. Lens array 13 includes several micro-convex lenses 131, each with a radius R of 100μm and a crown height H of 50μm. LED assembly 3 includes 12 LEDs, of which 6 are red LEDs 31 and 6 are blue LEDs 32, arranged alternately on both sides of the long side of lens 1. The distribution of lens array 13 on lens 1 is as follows: Figure 8 As shown, the light field distribution at a distance of 15mm from the lens is obtained, as follows. Figure 9 As shown, the uniformity at the center 10*10mm is 90%, where uniformity = (maximum illuminance value - minimum illuminance value) / maximum illuminance value.

[0056] In one embodiment, the LED lamp assembly 3 includes several LEDs, each comprising several LED chips of different colors, and the current of each LED chip can be controlled individually. For example, four types of LED chips are used: two red LED chips, one blue LED chip, and one green LED chip. All four types of LED chips are packaged in the same LED lamp; a total of six LEDs are used, with three LEDs placed on each side of the long side of the lens 1.

[0057] For example, the LED light includes a red LED chip, a blue LED chip, and a green LED chip; wherein the peak wavelength of the blue light is 460nm, the peak wavelength of the red light is 675nm, and the peak wavelength of the green light is 530nm.

[0059] In one embodiment, the LED light is equipped with a filter, which is attached to the light-emitting surface of the LED light. In practical use, excessively bright light shining directly into the eyes can cause glare, significantly affecting the user experience. Therefore, it is necessary to use LED chips with a narrow half-bandwidth. However, LEDs with narrow half-bandwidths are relatively difficult to obtain. A filter is added in front of the LED light; the filter is a multi-bandpass filter, and the specific filter parameters are designed based on the actual LED chip used. The filter can be attached to the surface of the LED light-emitting surface using optical adhesive.

[0060] For example, the LED light includes a red LED chip, a blue LED chip, and a green LED chip; wherein the peak wavelength of the blue light is 460nm, the peak wavelength of the red light is 675nm, and the peak wavelength of the green light is 530nm; the filter is a three-way filter with center wavelengths of 460nm, 675nm, and 530nm respectively, a bandwidth of 10nm, and a transmittance of ≥70%; the transmittance of the opaque band is ≤1%; the filter is attached to the surface of the LED light-emitting surface with optical adhesive.
