Contact Lenses With Infrared Vision?
Orlando (12257) writes "A story on Singularity Hub reports that "Researchers at the University of Michigan, led by electrical engineer Zhaohui Zhong, have devised a way to capture the infrared spectrum without requiring the cooling that makes infrared goggles so cumbersome." The method uses graphene and could one day lead to ultra light weight infrared vision technology."
A) Thermal imagers have not required cooling since approximately 1980.
(for other than extremely specialised applications.
B) Having a sensor does not magically mean it can be used in a contact lens.
You need electronics, LEDs, and focussing optics in order to get it into the eye in a coherent image.
So, we just blink and the TV channel will change?
No, but you will be blinded when using the remote control..

relevant part: "Humans cannot perceive UV light directly since the lens of the eye blocks most light in the wavelength range of 300-400 nm; shorter wavelengths are blocked by the cornea.[18] Nevertheless, the photoreceptors of the retina are sensitive to near UV light and people lacking a lens (a condition known as aphakia) perceive near UV light as whitish blue or whitish-violet, probably because all three types of cones are roughly equally sensitive to UV light, but blue cones a bit more.[19]"
A new colour, and all you have to do to be able to see it is have no lens.
I can see a business model where you'd sell these glasses from the backs of comic books.
