ClinConnect Summary

This clinical trial is looking at how providing free glasses to older adults in Hyderabad, India, can improve their overall quality of life. Specifically, the study is focused on people aged 60 and older who have vision problems due to refractive errors, which means their eyesight could be improved with the right glasses. The researchers want to see if giving these glasses can help reduce falls, depression, and improve social interactions and physical activity over a three-year period. Participants will be randomly assigned to either receive the glasses or not, while also providing information about their experiences and the cultural context of the study.

To be eligible, participants need to live in the community, plan to stay in the area for the duration of the study, and have specific vision impairments that could be corrected with glasses. They should also have good cognitive function, meaning their thinking and memory skills are intact. Those with serious health issues or other causes of vision impairment won't be included. If chosen for the trial, participants can expect to wear the glasses and share their experiences, which will help researchers understand the impact of better vision on their daily lives.
