ClinConnect Summary

This clinical trial is studying how young adults with different vision conditions—specifically myopia (nearsightedness) and hyperopia (farsightedness)—read and focus their eyes when using various types of corrective lenses, such as glasses and contact lenses. The researchers want to understand whether eye-tracking technology, using special Tobii glasses, can reliably measure eye movements and focusing abilities (called accommodation) during reading. They aim to find out if the way these two groups read is different and how well the Tobii glasses compare to traditional eye tests.

To participate in this trial, individuals must be between 18 to 30 years old and have specific vision requirements, such as mild to moderate nearsightedness or farsightedness, with good overall eye health. Participants will wear different types of lenses during the study while their eye movements and focusing behaviors are monitored. This trial is currently recruiting participants, and it's a great opportunity for eligible individuals to contribute to important research that could improve understanding of vision and reading behaviors.
