A study published last July in the medical journal JAMA investigated the relationship between poor vision and cognition (the application and processing of information in the brain).
The study found a connection between decreased visual acuity, decreased contrast sensitivity, and impaired binocular vision, and between concentration, memory, and language ability.
The result provides further evidence of the important connection between vision, eye health, and brain health.
On a personal note and from experience, I can add how important it is to insist on performing cognitive activities and not give them up: reading, writing, watching television, attending lectures, and more in order to maintain these abilities and thus preserve cognitive abilities, and the connection with the environment and reality.
