Contact Lenses With Infrared Vision? 99

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."

    Infrared essentially blocks out normal vision. While this may be useful as wearable computing, it wouldn't be useful if you had to poke around in your eye every time you needed to switch back to normal vision.

    When I go out to the desert on a clear day I'm getting a lot of infrared, if it blocked out normal vision I wouldn't need sunglasses (except that the glasses block UV). Perhaps what was meant is that the lens that would be needed to focus the light would block the IR and the lens for IR would block visible light. That's generally true except for near IR (NIR) but to separate NIR from visible IR a filter to do that would be used just as it is used in digital cameras.

    The article implies that it works across the IR spectrum but that's enormously wide - from about 700 nm to 1 mm wavelength with ever decreasing energy in the photons.

    I think that there is less information in the press release than meets the eye.
