He is referring to a mouse that instead of using a ball to detect movement, it uses light.

We did. You did. Yes we can. No.

That is the gist of what he said when he referred to 'optical mouse'.
Of course, most mice are optical in another sense anyway; the ball moves against rollers which are attached to grates, and the mouse shines a little light through the grate onto a pair of photo-detectors; its alternation gives the mouse its signal...

The early (I mean VERY early) ones did not have any light - It just had motion sensors (I think)

Well certain optical mouses brag that they work so well that you can use them on beds. However, I have never seen that work so I always use a mouse pad, though the lines in it don't seem to help or hurt it in any way from what I have experienced.

Optical mouses are indeed infrared - I know that they are experimenting with other kinds too.

I thought optical mice were in the visual spectrum...
Anybody here remember the oldfashioned optical mice that used real lasers, and required special reflective, gridded mousepads?

I've seen one that used a visable red laser, but didnt need any special mouse pad. It worked on anything. A bed, even someones head.

Did they really try that - That is like what certain people thought I did on this forum. (Sticking my head into microwave that has a broken front glass and turning it on)

Motion sensors use light.
Prior to seeing this, I assumed they were really weak EM signals that were just getting disorted (of course I didn't think about the fact that those little wheels & spokes are plastic)
An EM signal is, to wit, light (even if low enough frequency to be invisible)
As far as laser mice go, I can use mine directly on my fake wood desk, or on my jeans, or on my left sleeve, the top of my head...
Lasers are not necessarily dangerous. It's possible to make a powerful laser that can cut through things, but thinking a mouse laser is dangerous is like thinking a super soaker is dangerous just because Niagara falls is known to exist.
Yet, like a super-soaker, you don't want to aim a mouse laser at your eye.

If a laser was that dangerous they wouldnt sell it. Pointing a small laser at your head does no damage. I can do damage if you get a laser beam directly in the eye.
