New research gives seniors a good reason to get their eyes checked every year.
A study out of the University of Miami links poor vision to cognitive decline in adults ages 65 to 84.
"The study reinforces the importance of maintaining good vision in older adults, it will help to preserve their cognitive function," said the study's leader author D. Diane Zheng, a Ph.D. candidate with the University of Miami Department of Public Health Sciences.
As for why vision is tied to cognitive skills, Zheng says when you're visually impaired it affects the activities you do, which are important to keeping your brain sharp.
