Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a pair of vision correction glasses according to an embodiment of the present invention includes a lens 100 and a frame 200. The lens 100 is mounted on a frame 200. The lens 100 includes a display layer 120 and a transparent substrate 110, the display layer 120 is disposed inside the transparent substrate 110, the display layer 120 includes a plurality of light-emitting pixels 121, and the transparent substrate 110 and the display layer 120 are combined into a whole.

First, it is known that myopia is caused by the lengthening of the axis of the eye due to the thickening of the lens in the eyeball, the axis of the eye increases by 1mm, and the degree of myopia increases by about 270 degrees.

Sunlight or artificial light source 120 may be used as a stimulus to shorten the axial length of the eye. Thus, daily wear or periodic wear of the lens 100 with the light source 120 may be used as a treatment for myopia. The action mechanism is as follows: the light source 120 generates dopamine in the eye membrane, and the dopamine is beneficial to the length of the eye axis, so that the function of inhibiting or correcting the myopia degree is achieved.

Reference 1 discusses the refractive development of guinea pigs under different light intensity lighting conditions (5Lux, 500Lux, 10000Lux, white light, color temperature 6000K), and biological measurements of the eyeball (including diopter, ocular axis, corneal curvature) were repeated on the right eye of guinea pigs before the experiment and at the end of 12 weeks of lighting using a strip chart, an a-ultrasonic meter, and a keratometer, respectively, to compare the effect of light intensity on refractive development of guinea pigs, and to detect changes in retinal dopamine content. The conclusion states that: the high-intensity illumination can cause the growth of the axis of the eyeball of the guinea pig to slow down, the development of emmetropization to slow down, the refractive power to be far-sighted, and the weak light has no influence on the refractive development of the guinea pig. Strong light irradiation can cause the increase of the dopamine content in the guinea pig retina, and is probably one of the mechanisms of strong light causing the slow development of the emmetropization of the guinea pig.

Reference 2 discusses the effect of different spectral light environments on rhesus monkey refractive development. The conclusion states that: the short wavelength violet light induces the elongation and deceleration of the eye axis and the vitreous cavity of the rhesus monkey, and the emmetropization process is slowed down.

Accordingly, the illumination has a feasible basis for inducing dopamine production so as to inhibit the lengthening of the axis of the eye.

The utility model provides a pair of vision correction glasses, which can shorten the length of an eye axis through stimulation of a luminous pixel point 121, thereby achieving the functions of inhibiting myopia development and correcting myopia degree.

Optionally, the light-emitting pixel 121 adopted by the utility model is a Micro-LED light source. Preferably, the size of each Micro-LED light source 121 is between 2.5 μm and 10 μm.

The common stimulating light source 120 for treating or relieving myopia in the prior art mainly comprises a weak laser, a 315nmUVB light source and the like, and essentially, the light sources are all used for achieving the effect of shortening the axis of the eyes of human eyes and achieving the effect of inhibiting or preventing myopia; but the different light effects are different and cannot be generalized.

Further, the advantages of the Micro-LED light source used in the present invention for myopia treatment are mainly reflected in the following three aspects:

compared with weak laser, the Micro-LED light source has the advantages of safety, privacy, portability, convenience and obvious advantages;

the second Micro-LED light source and the Micro-LED light source can change different wavelengths according to different third-generation semiconductor processes, and are convenient and efficient;

and thirdly, the Micro-LED light source is an entire column of light source, and has obvious advantages compared with other light sources and a single-emission point light source.

Referring to fig. 2, as an embodiment of the present invention, the display layer 120 includes a plurality of light-emitting pixels 121, and the plurality of light-emitting pixels 121 are arranged in an array.

Different from the prior art of a midpoint emission light source, the light-emitting pixel points 121 of the array emit light more uniformly, have obvious advantages and can effectively avoid the loss of point light source light in the transmission process.

Furthermore, the Micro-LED light source adopted by the utility model is an element with a Micro watt level, and the refreshing frequency is between 100Hz and 1000 Hz.

The premise for ensuring that the lens 100 can be worn in daily life is that the substances embedded in the lens 100 do not affect the normal work and life of the user wearing the glasses, and generally, the light transmittance T of the lens 100 is greater than or equal to 95%.

If the side length of a single particle of the light-emitting pixel 121 is a and the distance is p, the light transmittance of the lens 100 is calculated according to the following formula:

duty ratio:

light transmittance:

correspondingly, referring to fig. 3, as an embodiment of the present invention, when the plurality of light-emitting pixels 121 are arranged in an array, the distance between adjacent light-emitting pixels 121 is preferably 0.5mm to 3 mm; the size of the single light emitting pixel 121 is preferably 2.5 μm to 10 μm.

The distance between the adjacent light-emitting pixel points 121 is taken as 1mm, the size of a single light-emitting pixel point 121 is 5 μm, and then the duty ratio of the light-emitting pixel points 121 is:

the light transmittance is:

therefore, the light transmittance of the lens 100 of the vision correction glasses provided by the utility model is far greater than the light transmittance standard of daily wearing, the light transmittance of the lens 100 is hardly influenced, and the vision correction glasses can be worn daily.
