A lot of us will see our vision deteriorate as we get older. That aspect of aging may be correctable if properly treated. Not being able to see clearly has another risk. That is the risk of being misdiagnosed with mild cognitive impairment. A study at the University of South Australia proves the point. Researchers recruited people with normal vision and gave them two cognitive tests—one required vision to complete the tasks, the other was based on verbal skills. Then, researchers fitted participants with goggles that simulated vision loss. The cognitive scores suffered. However, wearing goggles during verbal tests made no difference. Of several messages, one seems to be, “get those eyes checked.” The study appears in Scientific Reports.
