Summary
This trial is developing a device called a multiplexing prism that helps people who have lost one eye to see a wider field of view. They are testing a simpler design and way of fitting the device
Who is the study for?
This trial is for people who have lost vision in one eye for more than a year, but still have good vision (better than 20/32) in their other eye without any field defects. They should not have health issues like seizures or motor movement problems.
What is being tested?
The study is testing a device called a multiplexing prism designed to widen the visual field for those with sight in only one eye. The focus is on evaluating a new simplified design and how easy it is to fit this device to help with vision.
What are the potential side effects?
Since this trial involves an assistive device rather than medication, traditional side effects are not applicable. However, there may be discomfort or adjustment challenges when using the multiplexing prism.
