Description

Technical Field

[0001] The utility model relates to a pair of glasses, in particular to a pair of glasses with a main mirror for correcting vision and a secondary mirror for adjusting light fields. Background Art

[0002] In terms of vision management, myopia and hyperopia are mostly corrected with lenses. In recent years, some special lenses have also appeared, which mainly manage myopia by increasing peripheral defocus stimulation and balancing the contrast of adjacent cone cells. The special structure of special myopia management lenses is as follows:

[0003] (1) Peripheral defocus stimulation: Microstructures (microlenses, cylinders, diffraction slopes, etc.) are used to generate additional diopter, thereby generating peripheral defocus stimulation. For example, the patent "Spectacle Lens" (2013106281748) discloses a spectacle lens for correcting peripheral hyperopic defocus of the retina. The spectacle lens is composed of a first refractive area located in the central part and a second refractive area located in the peripheral part. The first refractive area is a uniform and smooth refractive mirror surface, and the second refractive area is a 360° annular refractive surface composed of multiple independent island-shaped microlenses.

[0004] (2) Balance the contrast of adjacent cone cells: Use the point diffusion myopia control technology (Diffusion Optics Technology, DOT) to create scattering and diffraction structures outside the central light-transmitting area, so that light is scattered or diffracted when passing through this area, thereby generating a lower signal difference between adjacent cones while maintaining excellent visual acuity and functional peripheral vision. For example, the control advantage lens created by Nikon has a small transparent circular hole in the center, and the other areas use Dot technology to create a scattering structure similar to a frosted layer.

[0005] The above-mentioned myopia management lenses have good effects in clinical and practical use, but their structure is fixed and long-term wearing cannot further optimize vision. If further optimization is to be achieved, the structure needs to be modified, which undoubtedly requires the wearer to replace the lenses as a whole, and the manufacturer also needs to provide more molds with special structures. In addition, it is not possible to use a pair of glasses to achieve myopia management with different functions, such as having complete peripheral defocus and Dot lenses at the same time. How to provide more vision management functions and meet the correction needs of different vision conditions without changing the main body of vision correction has become an urgent problem that needs to be solved. The solution to this problem can provide consumers with a more convenient vision management solution that can cope with different vision conditions. Utility Model Content

[0006] Purpose of the utility model: The purpose of the utility model is to provide a pair of glasses with a main mirror for correcting vision and a secondary mirror for adjusting the light field, so as to realize the main mirror for correcting vision and the secondary mirror for adjusting the light field.

[0007] Technical solution: The utility model includes a main mirror structure and a sub-mirror structure, the main mirror structure includes a main mirror frame and a main mirror; the sub-mirror structure includes a sub-mirror frame and a sub-mirror, the sub-mirror structure is adsorbed on the main mirror structure, and the main mirror is used to correct vision; the sub-mirror includes a base surface and a special structure, a variety of special structures are provided on the base surface, the special structures include one or more combinations of microlenses, Gaussian lenses, and scatterers, and the sub-mirror has the function of adjusting the incident light field and correcting the fundus light field.

[0008] The functions of adjusting the incident light field and correcting the fundus light field specifically include: local information stimulation, equalization of fundus light intensity, red and blue, and polarization imaging.

[0009] The local information stimulation is generated by a discrete non-closely-packed microlens array and a discretely distributed micron-sized Gaussian lens etched inside the base surface. The local information stimulation includes discrete multi-focused light spots in front of the retina and discrete multi-focused light spots behind the retina. The image plane position of the local information stimulation is controlled by controlling the focal length of the microlens and the diameter and depth of the Gaussian lens.

[0011] The homogenized fundus light intensity is generated by the closely adjacent microlens array and the scatterers etched inside the base surface, balancing the fundus light intensity distribution; under this function, the refractive power range of the microlenses in the microlens array is -10D to 10D, the diameter is 0.6mm to 5mm, and the interval between the microlenses is less than 0.1mm; the diameter of the scatterers etched inside the base surface is 0.01mm to 1mm, the depth is 0.01 to 1mm, and the interval between each other is 0.01 to 2mm; under this function, the microlenses 5 in the microlens array are consistent and evenly distributed.

[0012] The polarized imaging is achieved by a coating process, by coating films with polarization directions perpendicular to each other on the left and right lenses.

[0013] The base surface is a double plane or a front plane and a rear curved surface or two curved surfaces. When the base surface is two curved surfaces, the refractive power of the secondary mirror is plano; when the base surface is a double plane, the secondary mirror is afocal.

[0014] Magnetic points are installed on both the main mirror frame and the auxiliary mirror frame, and the auxiliary mirror frame is installed on the main mirror frame.

[0015] A magnetic point is installed on the secondary mirror, so that the secondary mirror is directly adsorbed on the main mirror frame.

[0016] Beneficial effects: The utility model makes it easier to adjust the vision correction of the human eye and select the light field adjustment effect of the fundus through the combination of main and auxiliary mirrors. Through the combination of multiple groups of auxiliary mirrors, stimulation signals can be generated at different distances and the fundus light intensity can be balanced. At the same time, red, blue and polarized lenses can be provided for amblyopia and fusion problems. It is also convenient to wear and use. The main mirror is used to correct vision at ordinary times. Different auxiliary mirrors are installed when light field adjustment is needed. Different auxiliary mirrors and auxiliary mirrors of the same type with different parameters can be used in different time periods to better adjust the fundus light field and achieve more effective management of vision.
