It is estimated that over 30 million people are either blind or partially sighted in Europe, including countries outside the European Union. In general, blind people have no vision, while partially sighted people retain some vision, from light perception to the ability to see shapes, colours, or contrasts.

First, if the blind capture an image of a specific location using the ear-mounted camera, the captured image is transmitted to the recognition server using a smartphone that is synchronized with the camera. The recognition server sequentially performs human detection, object detection and action recognition by analyzing human poses .

Engineering infrared light sensitivity in the blind human retina could restore visual function in patients with regional retinal degeneration. However, current approaches are complex and contain non-human biological components. Using rational protein design we engineered human TRPV1 channels (Δ786-840) with temperature sensitivity shifted from 45 to 41C that enabled near-infrared light ...

Braille is read by people who are blind, deafblind or who have low vision, and by both those born with a visual impairment and those who experience sight loss later in life. Braille may also be used by print impaired people, who although may be fully sighted, due to a physical disability are unable to read print. [ 39 ]
