Amblyopia typoscope based on AR (Augmented Reality) glasses

Abstract

The embodiment of the present invention discloses an amblyopia typoscope based on AR (Augmented Reality) glasses, including a camera system, an input device, a circuit control system, and a waveguidedisplay system. The camera is used to capture surrounding objects, processed image information is projected on an optical waveguide by using the projection technology after electronic amplification and image special processing, the optical waveguide can reflect an image to the human eye, the image entering the human eye can help the visually impaired to see the surrounding objects by methods of amplification, brightness increase, contrast improvement and the like. The amblyopia typoscope provided by the embodiment relates to the technical field of display and electronic assistive vision, combines optical waveguide display technology, augmented reality technology, electronic amplification technology and image processing technology, adopts waveguide transmissive display, is different from the same kind of typoscope products using closed-type display, and prevents the symptoms of dizziness and nausea caused by conflict between the visual sense and the motion sense due to visual closure. The amblyopia typoscope is compact and light, and has a lens of the thickness being only 1.7mm and much lower than the thickness of the display module of the similar head-mounted electronic visual aidproduct; the amblyopia typoscope is smaller in size and closer to a pair of ordinary sunglasses, is not obvious and cannot cause special attention when being worn, and can well help the visually impaired to see the near and distant things better.

Description

technical field [0001] The invention relates to the field of waveguide display and the field of electronic vision aid technology, in particular to a low vision aid based on AR glasses. 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, reducing the...

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
