Vision training: Mobile app improved pilots’ vision (Aircraft Owners and Pilots Association):
“Military pilots (and other test subjects) have improved their vision after a few weeks of training with a new application for mobile devices—an application now available to the public.
The technology has helped dedicated users reverse age-related vision loss, and to help younger people improve on 20/20. Their eyes—including lenses, muscles, and receptors that send signals to the optic nerve—are only incidentally involved: The real work is going on inside the brain…
More specifically, the GlassesOff application is designed to facilitate “perceptual learning,” which refers to the brain’s ability to improve perception (visual, in this case) through training. Unlike corrective lenses or laser surgery, which improve the quality of the image captured by the eye, GlassesOff improves vision without any change to the eye itself. The results are achieved by enhancing the brain’s visual processing speed and accuracy through various exercises requiring users to interpret images on the screen in sessions that last 12 to 15 minutes, three times a week. Over a period of a few weeks, the brain adapts to more efficiently process images, even if they are flawed by lenses that have lost focus.”
