A camera and some rudimentary software should be a pretty good fix for color blindness. A camera and modern AI is a decent mitigation to partial or perhaps even complete blindness (prior art: Be My Eyes). A microphone, STT, and display would help with deafness.

There is a short video on the BBC website of a blind person using them to give an audible warning of uneven pavement/sidewalks in front of them.

E.g. video to speech for a blind person.

Video to speech is audible narration.
