ClinConnect Summary

This clinical trial is studying a new type of blue-blocking glasses designed to help reduce visual fatigue, especially for people who spend a lot of time on electronic devices like computers and smartphones. The trial will evaluate how these glasses affect eye comfort and function by measuring things like eye strain and tear film stability. Participants will wear either the new glasses or regular glasses while using screens, and researchers will compare their eye health indicators before and after using the glasses.

To be eligible for this study, participants must be adults aged 65 to 74, with a specific range of vision correction needs. They should not have any significant eye conditions or recent eye surgeries. Participants will need to agree to complete various eye tests and sign a consent form. If you join the trial, you can expect to help contribute to research that could lead to better eye care solutions for people experiencing visual fatigue.
