The article says: the interference pattern tends to cancel out some of the light passing through the lens, which reduces the contrast of images viewed through it. The example image also shows this effect. The claim is that: the brain adapts to and minimises the reduced contrast within a few seconds. My point was that this adaptation may not work for everyone or may not be comfortable. Also when the glasses are taken off do your eyes have to readjust to normal contrast?
