Ultraviolet and Infrared Rays.

Is it true there are people with a genetic condition that can see infra red and ultra violet rays?

No idea, but there is no physical reason that they shouldn't be able to. Visible light is a reasonably small part of the spectrum.

Science teachers that have taught for years have reported that occasionally, someone will claim to be seeing just into the near IR range.

We are not talking about seeing heat or UV at all.

Usually, teachers will give students a prism and ask them to sketch out the rainbow. Occasionally, someone will draw the red farther than it should go - that is, into the near IR.

When questioned to whether it was just a mistake, they claim it was not.

UV light cannot penetrate the lens of the human eye. No idea regarding IR.

According to that richard hammond series that was on recently we can all see uv but the lenses in our eyes filter it out to prevent damage to our retinas

I presume it's possible for the lens to somehow be altered to allow UV penetrate? I don't really know, I know nothing about biology or the biological make-up of the eye.

some people have had their lenses removed and see a lot more blue afterwards
