I have to say, I found this new research fascinating as I had been experiencing something similar to the contrast sensitivity described. And I was delighted to see you could train your eyes to counteract the perceptions that can cause a stumble.
Jan Hoffman writes at the NY Times, “As adults age, vision deteriorates. One common type of decline is in contrast sensitivity, the ability to distinguish gradations of light to dark, making it possible to discern where one object ends and another begins.
“When an older adult descends a flight of stairs, for example, she may not tell the edge of one step from the next, so she stumbles. At night, an older driver may squint to see the edge of white road stripes on blacktop. Caught in the glare of headlights, he swerves.
“But new research suggests that contrast sensitivity can be improved with brain-training exercises. In a study published [in March] in Psychological Science, researchers at the University of California, Riverside, and Brown University showed that after just five sessions of behavioral exercises, the vision of 16 people in their 60s and 70s significantly improved.”
