I've been excited about the Lynx R-1 mixed reality headset since I first heard about it, and it just keeps getting better. Open source, and the hardware is as open as they can make it. Much lower latency than others, more brightness, raw access to sensors and frames.

They didn't design it to help people with low vision, but check this talk out. Even without specific software this thing is giving people their vision back. Think what it could do with more software features to aid vision.
