Embodiment 1
[0026] Such as figure 1 As shown, a visual aid method for visually impaired persons, comprising:
[0027] S1, providing AR glasses based on planar waveguide imaging;
[0028] AR glasses based on planar waveguide imaging are mainly composed of microdisplays and waveguide display modules. The belt will not cause pressure on the bridge of the nose and the head, and will not attract attention, which improves the wearing comfort.
[0029] AR glasses include a camera system and an input device; the camera system is used to record the surrounding environment information; the input device includes buttons, touch pads and Bluetooth control devices, which are operated by the user and feed back signals to the circuit control system.
[0030] S2, using AR glasses imaging to detect the wearer's eye function parameters including central visual acuity, contrast sensitivity, fusion function and stereo vision;
[0031] Such as figure 2 As shown, the Snellen diagram is projected to the the...
Embodiment 2
[0043] A visual aid system for visually impaired persons, used to implement the method of Embodiment 1.
[0044] All technical solutions of various devices or equipment combined with software produced by the above-mentioned visual aid method for visually impaired persons belong to the protection scope of the patent of the present invention.
Embodiment 3
[0046] A kind of smart AR glasses, which is used to implement the method of Embodiment 1.
[0047] Compared with the visual assistance system for visually impaired persons in the second embodiment, the smart AR glasses in this embodiment are the best choice for implementing the method described in the first embodiment.
[0048] In one embodiment, a color-changing film is coated on the planar waveguide, and the color-changing film can change color according to changes in the intensity of external ultraviolet rays, so as to block external strong light and protect the eyes.
