Study Links Vision Impairment to Nearly 20% of Dementia Cases

Research suggests better eye health could significantly reduce dementia rates among older adults.

Up to 19% of dementia cases are associated with vision impairments, according to Johns Hopkins University research.
The study analyzed data from 2,767 American adults aged 65 and older.
Types of vision impairments linked to dementia include near acuity, distance acuity, and contrast sensitivity.
More than 90% of vision impairments are preventable or correctable, highlighting the importance of regular eye exams.
Researchers emphasize the need for further studies to explore the causal relationship between vision and dementia.
