Problems solved by technology

However, the technical solutions disclosed in the existing patent documents cannot accurately display the power of the liquid crystal lens, and cannot check the power of the glasses in real time, resulting in the inability to achieve accurate and rapid adjustment according to the actual vision power.
Once the degree adjustment is not accurate, it will inevitably cause damage to the human eye.
Because when performing vision correction (taking myopia as an example), when the degree of adjustment is greater than the actual degree, although the human eye can see things clearly, but wearing glasses with a high number for a long time will cause dizziness and cause certain damage to the eyes.
Moreover, when repeatedly adjusting the degree of glasses, multiple zooming processes are also not conducive to vision health

Embodiment 1

[0038] The spectacles in this embodiment adopt the mode of capturing voice to automatically adjust the diopter of the lens. The display device 16 includes a voice capture device 17 and an adjustment button 15, the voice capture device 17 is electrically connected to the adjustment button 15, the voice capture device 17 recognizes the voice through a voice sensor and feeds back to the adjustment button 15, and the adjustment button 15 is electrically connected to the controller , under the guidance of voice, it can automatically adjust up or down to meet the recognition needs in different environments and at different times. Moreover, a display screen for displaying degrees is provided on the adjustment button 15, and the display screen converts the output voltage of the controller driving circuit into degrees through a conversion unit. In order to check the real-time prescription of glasses conveniently, the display device 16 can be arranged on the inside or outside of the tem...

Embodiment 2

[0067] In the out-of-focus initialization state, such as Figure 7 As shown, the image capture device 18 collects images of the human eye through a camera and a sensor, and performs image distribution and grayscale control through an image preprocessing module; after passing through an arithmetic circuit, it feeds back to the adjustment button 15, and the adjustment button 15 controls the adjustment button 15 according to the feedback information. The driving circuit is used for voltage adjustment and focal length adjustment; after the adjustment is completed, the adjusted output voltage is converted into degrees by the conversion unit, and displayed on the display screen.

[0068] The glasses require that the refraction of light should be uniform, that is, the power of each light refraction should be equal. For the problem of astigmatism, if the refraction power is not equal, there are large and small, so that the light cannot be aggregated to one point, but scattered at multi...

Abstract

The invention relates to the technical field of liquid crystal optics and in particular relates to a pair of eyeglasses. The pair of eyeglasses comprises an eyeglass frame, liquid crystal lenses, a controller and a display device, wherein the liquid crystal lenses are arranged on the eyeglass frame; liquid crystal layers are arranged in the liquid crystal lenses; the controller outputs voltage to the liquid crystal lenses, so that the arrangement direction of liquid crystal molecules in the liquid crystal layers is changed; the display device is electrically connected with the controller and is used for converting the output voltage and displaying the voltage by degrees, so that the degrees of the eyeglasses is checked in real time, and the degrees can be rapidly, accurately and automatically adjusted. According to the eyeglasses, the degrees of the liquid crystal lenses is timely adjusted according to change of the degrees of the vision, the eyeglasses can be freely switched between glasses for shortsightedness and glasses for farsightedness, and shortsightedness and farsightedness can be corrected.

Description

technical field [0001] The invention relates to the technical field of liquid crystal optics, in particular to glasses including liquid crystal lens lenses. Background technique [0002] At present, vision health problems plague many people. The survey found that tens of millions of children suffering from myopia, amblyopia and hyperopia need treatment every year, and children and adolescents under the age of 18 develop at a rate of 50-100 degrees per semester after vision decline. Vision health problems, especially the myopia problem of young people, seriously affect people's daily life and work; and as they grow older, the elderly generally need to wear reading glasses to see objects normally, which also brings troubles to the lives of the elderly and inconvenience. [0003] The eyeball is composed of the eyeball wall and its contents. The eyeball wall includes the adventitia, media and intima. The adventitia is composed of colorless and transparent cornea and white toug...
