ClinConnect Summary

This clinical trial is studying how people perceive the locations of objects around them while they are moving, especially at distances between 2 and 25 meters. This ability is important for everyday activities like walking and driving. The researchers want to understand how our eyes and brain work together to judge distances and how problems with vision or the nervous system might affect this ability. This knowledge could help improve mobility and navigation for individuals with certain visual impairments.

The trial is looking for participants aged 18 to 40 years who have normal or corrected vision (like wearing glasses) and good depth perception. However, people with a history of eye diseases or who have difficulty moving may not be eligible to join. If you participate, you will help contribute to important research that could benefit many people with vision challenges. Please note that due to the time commitment required, pregnant women and other vulnerable groups will not be included in this study.
