Prism glasses could help half-blind patients spot dangers
NCT ID NCT04827147
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two types of high-power prism glasses designed to expand the field of view for people with homonymous hemianopia, a condition where the same half of vision is missing in both eyes. About 64 participants will use the glasses while walking in a virtual reality simulation to see if they can better detect approaching hazards from their blind side. The goal is to improve safety and independence in daily life.
