I came across the Ultimeyes app and am very concerned many people will be throwing away their money.
ULTIMEYES® is a non-invasive interactive program designed specifically to improve vision by optimizing visual processing in just four simple 25-minute sessions per week for a total duration of eight weeks.
Contrast sensitivity, which is the visual skill that enables you to distinguish objects in dim light and against obscure backgrounds, increased dramatically among users in these studies.
UltimEyes presents you with the increasingly difficult challenge of identifying faint and fuzzy Gabor stimuli, which are shown against a hazy, gray background. Among other tests, the blurry blobs might slowly materialize on the screen, or you might be tasked to find multiple blobs as they grow slightly less faint. It isn't exactly fun, but it's challenging, and the sessions are short.
I have heard of eye exercises before such as looking "past" something then look at that object very near to your eyes.
In a study published this week in the journal Current Biology (Supplemental data and procedures), Seitz worked with 19 players on the University of California, Riverside, baseball team, and showed that his app UltimEyes lengthened the distance at which the players could see clearly by an average of 31 percent. After using the app for 30 25-minute intervals, players saw an improvement that pushed many of them beyond normal 20/20 vision, including seven who attained freakishly good 20/7.5 vision—meaning that at a distance of 20 feet, they were clearly seeing what someone with normal vision could see at no farther than 7.5 feet away.
Is this a scientifically supported claim?
