Does Vision Affect Cognitive Ability?

The question of whether vision plays a role in influencing cognitive abilities has been a subject of interest and investigation. Longitudinal studies have yielded significant findings that strengthen the hypothesis suggesting that visual impairment (VI) might act as a potential risk factor for cognitive impairment, cognitive decline, or even the onset of dementia. In fact, a comprehensive review of the literature identified a total of 91 studies that have reported various associations between the deterioration of visual functions and declines in cognitive abilities. These collective findings underscore the importance of considering visual health as a potential contributor to cognitive well-being and offer valuable insights into the relationship between vision and cognitive functioning.

How Does Vision Problems Affect The Brain?

Vision problems can have a significant impact on the brain. According to Dr. Swenor, a renowned expert in the field, when individuals experience vision loss, they tend to modify their lifestyle.

Dr. Swenor further emphasizes that such alterations can accelerate the process of cognitive decline. This insight was shared on September 9, 2021.
