Testing prism glasses for certain types of visual field loss
Part of Brain & nervous system, Eyes & vision clinical trials.
This study checks whether different prism “glass” settings are feasible and helpful for people with certain types of vision field loss. You would attend testing sessions lasting about 2–4 hours to see how well the prism glasses can be used safely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have vision field loss (either side/peripheral loss or loss on one half of your field)
- Your best-seeing eye has vision of at least 20/50
- You are healthy enough to sit through sessions lasting 2–4 hours
- You can walk short distances by yourself
- You can understand the study and agree to take part (informed consent) and you speak English
- You should not have recent seizures (in the last 6 months) and should not have balance or thinking problems that could affect walking or using prism glasses

This trial studies whether a virtual reality (VR) eye test can measure a child’s vision field (where they can see) instead of standard testing. It may help clinics test children in a more comfortable way, especially if traditional tests are hard for kids.
This study tests whether vision rehabilitation exercises done at home, guided by brain imaging, can help people regain vision after a stroke, brain injury, or tumor. Participants will use brain scans to personalize their therapy.
This study tests whether prism adaptation therapy (wearing special glasses that shift how you see) can help improve attention and function after a right-brain stroke. You may be eligible if you recently had a first right-brain stroke and can sit up to take part in the therapy.
This study tests a new vision-related “prismatic adaptation” task to see if it could help people with daily independence after a brain injury. Because you’d be asked to do technical testing, the main goal is to understand how the test works in healthy people.
This study tests if a simple eye-exercise technique (prism adaptation) can help people who, after a recent stroke or brain surgery, have trouble noticing one side of their world. If you qualify, you'll try this training to see if it improves your attention to the neglected side.
This trial tests whether adjusting prism glasses over a shorter time helps people with symptomatic inward eye turn (esophoria) and whether surgery results are better after that adaptation. It may be helpful if you have double vision, eye strain, or headaches that worsen with fatigue or reading.
