The human eye can distinguish thousands of different colors and shades, but there are still, many things that we just cannot see. However, with the help of UV light, some of these things can become visible to us as well. People born with something called Aphakia, which is the absence of the lens of the eye that normally blocks ultraviolet light, can see them. For the rest of us, UV light itself is invisible, however many things can appear different under this light that we’d find interesting.
