Summary

The aim of this project is to explore whether vision correction can effectively slow cognitive decline in older adults.

The primary question it seeks to answer is: Can providing free near and/or distance vision correction glasses to older adults with refractive errors or uncorrected vision, who have normal baseline cognition and hearing, reduce the rate of cognitive decline over 36 months in a cost-effective manner? Researchers will compare the rate of cognitive decline over 36 months between older adults who receive refractive correction and those who do not.

  • Cognition Disorders

Interventions

DEVICE

Free Prescription Glasses

Participants can choose from a variety of frames, and the research team will customize the glasses according to their pupillary distance and prescription. Once the glasses are ready, they will be provided to the participants following standard usage instructions. In case of loss or damage, participants should report it to the project team and will be provided with replacement glasses as needed. Each year, participants in the intervention group will undergo an eye exam to assess changes in vision, and their glasses prescription will be updated if necessary.
