Eyes are the windows to the soul, and now may also become windows to protect cognition!
A research in the United States earlier tested both visual and cognitive abilities of more than 2000 elderly, and found that the poorer the vision, the poorer the cognition.
In the subsequent eight years, they found that among these elderly the more decline in visual acuity, the more decline in the score in the cognitive test.
The researchers are not able to explain, but they thought vision can provide simulation to the brain so can help reduce decline in cognition.
Therefore, everyone should regularly take the eyes of the elderly at home, equip them with appropriate glasses, and deal with their eye diseases as soon as possible, so that their soul window will remain bright!
