I found a new product, but I'm afraid it's not safe. Can you help me understand what the safety limits are when it comes to near-infrared light focused on your eyes is?
I'm assuming the wavelength of the light is important, but probably more important is the amount of focus. (For instance, visible light isn't very dangerous unless it's focused in a laser).
Here is their quote about safety on the FAQ:
Yes, The Eye Tribe Tracker complies with the essential health and safety requirements set by the FCC and CE directives. The Eye Tribe Tracker is using near-infrared illumination, it conforms with the EN 62471 standard and we have obtained an EU declaration of conformity.
