Amblyopia visual aid based on waveguide display

Abstract

The embodiment of the invention discloses an amblyopia visual aid based on waveguide display, which comprises a camera system, an input device, a circuit control system, a waveguide display system andshielding pieces. The amblyopia visual aid provided by the embodiment of the invention relates to the field of waveguide display and the field of electronic visual aid technologies, combines an optical waveguide display technology, a reality enhancement technology, an electronic amplification technology and an image processing technology and adopts waveguide transmission display. Different from similar visual aid products adopting closed display, the amblyopia visual aid does not result in the symptoms such as dizziness and nausea caused by visual-somatosensory conflicts due to the closed vision. The amblyopia visual aid provided by the embodiment of the invention is compact, light, small in size, more similar to ordinary sunglasses and not obvious when being worn, does not cause specialattention and can better help the amblyopic people to observe the things around.

Description

technical field [0001] The invention relates to the field of waveguide display and the technical field of electronic vision aids, in particular to an amblyopia vision aid based on waveguide display. Background technique [0002] Amblyopia is a developmental disorder eye disease, often due to strabismus, anisometropia and high degree of refractive error caused. In addition, usually one out of nine people who have reached the age of sixty-five will have amblyopia, and one in four people who have reached the age of eighty will have amblyopia. Amblyopia cannot be corrected and recovered by general glasses. These people cannot see objects near and far away, which seriously affects their normal life. [0003] There are many amblyopia products on the market, such as optical telescopic vision aids, electronic vision aids, etc. Patent 200720060305 discloses a new type of telescope, which uses liquid optical lens groups to replace traditional mechanically adjusted optical lens groups...

AI Technical Summary

Problems solved by technology

Amblyopia cannot be corrected and recovered by ordinary glasses. These people cannot see objects near and far away, which seriously affects their normal life.

[0003] There are many amblyopia products on the market, such as optical telescopic vision aids, electronic vision aids, etc. Patent 200720060305 discloses a new type of telescope, which uses liquid optical lens groups to replace traditional mechanically adjusted optical lens groups, reducing the The volume of the entire telescope is easy to carry, but the target of this telescope is infinity, and it cannot image nearby objects; although the patent 2009100959309 can realize imaging of nearby objects, the appearance of the telescope is too abrupt, and objects at different distances can be observed Manual adjustment is also required; patent 2007200063788 has a high magnification and high definition, but it is inconvenient to carry, and it is very obvious to wear, and the amblyopia group does not want to be noticed because of this, and they also want to live like normal people
