With my cloudy yellowing (UV-filtering) natural lens removed, I see the world in a new light (more on that in a moment) as everything is brighter and colors are more vivid ... plus in focus. As a typical Slashdot reader, I've been myopic since childhood, so it's wonderful not to have to wear glasses/contacts for distance. One interesting oddity is that I can now see ultraviolet light — it seems that there are a few people who have photoreceptors sensitive below 400nm into the UV spectrum. I've done some testing with a Black Light and UV filter to confirm this but would love to do more conclusive testing such as using a Monochromator — anyone in the Boulder, Colorado area have access to one? And any suggestions from Slashdot readers on how I can further explore this phenomenon? While I can't see dead people, I guess I have a 'superpower' ... although I'm not sure a middle-aged suburbanite dad should don purple tights and cape to become a crime-fighter!"
