There is no accessibility reason ever for covering up the light or recording. I will accept describing objects in FOV etc but nothing should be persistable or sent to a third party that trains on them and saves them without the consent of everyone in view, a company should build non-criminal glasses without these feature sets and have insurance pay for them.
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.
