Do you believe in Optography? This is the technique by which images are extracted from dead eyes; revealing the last thing they ever saw.
Most people think this is a myth but there is scientific proof behind the idea.
This video is a good look at the science and theory behind Optography.
Caution – it may freak you out a little as the video includes actual photographs of images captured from eyes.
If you’re not sure whether this is real or not then a quick trip to Wikipedia’s page on the subject should put you at ease. Optography is a thing but it’s usefulness may not be.

Do you have any other examples of “Fringe Science” that sound too odd to be real?
