Summary
This study tests special glasses with high-power prisms that shift images from blind spots into the wearer's remaining vision. Researchers will try different designs to see which best expands the field of view and helps people detect obstacles while walking. The trial involves about 20 participants with conditions like hemianopia or tunnel vision, who will attend several sessions for fitting and testing.
