Isn't in dangerous to use so many diods to shine at you like in the tracking fingers project? I was trying to find something about this on the internet but found only that it's very dangerous with high emmiting infrared light although remotes and such are usually safe because of safety regulations.

S what do you think about this? After reading about laser safety on wikipedia I'm not very comfortable with looking directly at an infrared diode since I can't tell whether it "hurts" or not.

Search through the board, there was a detailed discussion on this exact topic. From memory the recomendation is don't purely due to lack of knowledge.

An opthemologist may know more, do you know one?

I'm sure others would love to know the facts. I would hate to think the idea hasn't been explored becuase of a faux fear.

LED's would not damage your eyes when used in an array. Eye damage occurs from thermals put out by IR light. In lasers this is very possble and can burn the retina.

Yes I found lots that support all sorts of arguements about eye damage and light frequencies. However, I like my eyeballs just the way they are. Untill we get a concrete medically based opinion, I would persoanlly still run on the skinny side!

But ultimately we are all big boys and girls so it is our choice.
