Simulated Walking With Multiplexing Prism for Field Expansion in Monocular Vision

Withdrawn before enrolling · Not applicable

Conditions studied: One Eye Blindness, Blind Left Eye, Blind Right Eye

In brief

The investigators are developing an assistive device, known as multiplexing prism that expands the field of view for individuals with acquired monocular vision (loss of an eye). The investigators will test the efficacy of the prism in improving the detection of colliding pedestrians during a simulated walking task.
