Humans Have Been Able To Perceive Infrared Light This Whole Time

The human eye is a more complex and mysterious thing than we thought. Recently, a group of scientists were puzzled by flashes of green light they saw from an infrared laser, whose light should have been far outside the visible spectrum. Like scientists do, they investigated. Human eyes do indeed perceive infrared light, they found, but not they same way they perceive ordinary colours. It's weirder than that.

In a handbasket
I saw that article and I'm thinking about hooking up a 940nm LED to a variable frequency PWM circuit to see if I can detect anything at a specific frequency.

I remember another article from a few months ago where a couple of guys stated that they were able to extend their sensitivity very slightly into the IR range through some unusual dietary methods. I'm not inclined to try that one though.
