Impact of Glasses for Vision Problems on Cognitive Function in Rural Older Adults

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.
