Study Summary

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 are testing a simplified design and fitting protocol to provide field expansion for individuals with acquired monocular vision.

Eligibility Criteria

Inclusion
