NCT ID NCT07531667
First seen Apr 21, 2026 · Last updated Jun 23, 2026 · Updated 9 times
Summary
This study tested whether a special stick-on lens called a Fresnel prism can help people with hemianopia (blindness on one side of vision) see a wider area. Twenty-five adults with this condition wore the prism on their glasses for a period. The researchers measured changes in their visual field and how comfortable the prism felt. The goal was to see if this simple device could improve mobility and reduce fall risk.

Active substance
Fresnel prism (a special stick-on lens placed on glasses to widen the field of vision)
What this could lead to
If it works, this could offer a simple, non-surgical way to help people with hemianopia see more to their blind side, reducing falls and improving confidence.
What could go wrong
This was a small, single-site study with only 25 participants and no comparison group. The prism may cause visual confusion or discomfort, and results may not apply to everyone.
