Description

A red light instrument for improving visual acuity

Technical Field

The utility model belongs to the field of optical application and ophthalmic medical treatment, and in particular relates to a red light instrument for improving the visual acuity of the retina of human eyes.

Background Art

The cones and rods on the human retina will age at a certain age, especially after the age of 40. The latest research results of Professor Jeffrey's team at University College London have been published in the SCI journal "Gerontology" in 2020. The research results show that irradiating the human eye with red light with a wavelength of 650nm to 690nm, especially the central wavelength of 670nm, can significantly improve the retinal aging of middle-aged and elderly people and improve visual acuity.

The report clearly disclosed that "mitochondria have a specific sensitivity to long-wave light that affects their performance: red light with a wavelength between 650 and 900nm improves mitochondrial performance, thereby increasing energy production; while the retina ages faster than other organs, with a 70% reduction in ATP over a lifetime; resulting in a significant decline in photoreceptor function because they lack energy to perform their normal functions. China Daily: https://ms.mbd.baidu.com/r/L8TQ8v1aH6?f=cp&u=7249c80d335fc5cd Abstract: As we age, our eyes are no longer as bright as they were when we were young, because our eyes age faster than other organs in the body. New research has found that staring at red light for 3 minutes a day can effectively improve vision, and the effect is particularly significant for the elderly.

It can be seen that the retina of people over 40 years old begins to degenerate and age, which reduces the visual acuity of the retina. At present, there is no better solution except taking or applying some lutein and other related drugs, eye drops and eye ointments, and pressure massage of the eyes.

Therefore, those skilled in the art are committed to providing a red light instrument for improving visual acuity that can effectively solve the above technical problems.

A red light meter for improving visual acuity includes a monocular unit 100, wherein the monocular unit 100 includes a housing 1, a light source device 2 is disposed at the rear end of the housing 1, a front end of the housing 1 is a visual end 5, and a switch button 21 (light source control system) for controlling the light source device 2 is disposed on the housing 1;

The housing 1 is provided with a limit step 20 and an elastic retaining ring 11, two O-rings 10 are provided between the limit step 20 and the elastic retaining ring 11, and a narrow-band filter 3 is provided between each of the O-rings 10. The narrow-band filter 3 can generate red light with a wavelength in the range of 650 nanometers to 690 nanometers. The substrate of the narrow-band filter 3 is optical glass, and the narrow-band filter 3 is made by vacuum coating process.

In this embodiment, the narrowband filter 3 can selectively pass red light with a wavelength of 650 nanometers to 690 nanometers. The narrowband filter 3 is made by vacuum coating technology, which can selectively pass the light source, thereby generating the required red light. The substrate of the narrowband filter 3 is fragile optical glass, so it is installed between two rubber shock-absorbing O-rings 10. One side of the two O-rings 10 is a step, and the other side is positioned by a hole with an elastic retaining ring 11. This structure prevents the narrowband filter 3 from shaking and facilitates disassembly and assembly.

The housing 1 is cylindrical, elliptical or square. In actual use, it is not limited to cylindrical, elliptical and square shapes, and other shapes can also be used. The shape adopted should be aesthetically pleasing and easy to install and use. As a preferred embodiment, a cylindrical shape is adopted in this embodiment.

The switch button 21 is connected to the light source device 2 through a wire. The irradiation power and intensity of the light source can be adjusted and limited to meet the relevant laser use safety standards. The control system can set the irradiation time and can also be designed in any position that is convenient for installation and operation.

The visual end 5 is a hollow structure, and the cross section of the visual end 5 is circular or elliptical. A detachable eye protection cover is provided on the outer side of the visual end 5. The light source device 2 generates red light of a specific wavelength and emits it from the other end of the housing 1.

When used, the red light controlled within the safe range directly illuminates the human eye retina. For people over 40 years old, irradiation for more than three minutes a day can significantly improve the visual acuity of the retina that has begun to degenerate and age.

In order to facilitate the use of users, the red light instrument of the utility model can be designed as a head-mounted type, a hand-held type, or a base-fixed type.
