Engineer and self described nerd Alek Komarnitsky describes how post cataract surgery, he now sees an expanded color spectrum. What could the lilac glow beyond violet be — auras, pet spirits, Venus rays? Via Komar:
Numerous people who have also had their natural lens removed have written me saying they see similar to what I describe below. I’ve been very happy so far with the Crystals implant for cataract surgery. But one unexpected/interesting aspect is I see a violet glow that others do not … I’m seeing Ultraviolet light!
An eye surgeon recently wrote about blue-violet color changes after Crystalens implants and his experience is that only 3% of patients have experienced (or mentioned!) this phenomena … but some people may just have more sensitive photoreceptors, so the vast majority of the patients would not see this.
Some related interesting tidbits include during WWII, the British used aphakics for signaling using UV lights … since only they could see it. When the initial telescopic observations of Venus were done, a small number of people said they could “see more” … which was later confirmed when UV sensitive equipment became available…
