Overview

What we are studying

We are developing a prism glass for individuals with monocular vision loss (loss of an eye). Specifically, we are studying the performance of the prism glasses in helping these individuals in detecting colliding pedestrian in simulated walking scenarios.


Why it is important

Detecting and avoiding obstacles when walking can be difficult for those with visual field loss, such as acquired monocular vision. We are developing a new prism glass to improve spatial awareness of the surroundings, particularly during walking tasks.
