NCT05458323 · RECRUITING
Cognitive Level Enhancement Through Vision Exams and Refraction
This trial is testing whether giving free prescription glasses to older adults in Hyderabad, India who have uncorrected vision problems can improve cognition, quality of life, mood, social connection, and reduce falls over three years. It is a Phase NA trial, meaning it is evaluating a practical intervention rather than a drug, and is designed to measure real-world outcomes in a community setting. Details on broader generalizability are limited so far.
