Here's an amazing reason to be disappointed with a little vision: An eye examination is good for your mind.
Yes, regular checkups of your eyes and correcting your eyesight can help greatly reduce your risk of developing memory loss.
Problem Eye?
Compared with people who felt that their opinion was poor, people who rated their opinion as better or better had a 63 percent chance of developing dementia over a 9-year study period. And although participants did not show any signs of dementia or depression at the start of the study, the researchers found that those with severe depression who did not bother to go to the eye doctor had a 9.5-fold chance of developing Alzheimer's disease. On the other hand, the risk of dementia was not very high in people whose initial outlook was not so great but who had problems that were professionally corrected.
Visual Health Cues
It is still unclear how the health of our eyes can be linked to brain function. But some studies have found similar links between decreased vision and decreased thinking ability. It may be that visual impairment makes it difficult to maintain good living habits that are known for preventing the risk of dementia, such as regular exercise and mind-altering activities.
