Free-track IR 2 DOF?

Well just don't be clever and try and use industrial IR lasers for illumination.

I would probably also avoid pointing a military night vision IR spotlight directly into your face from 1m away as well

In those cases near light frequency IR radiation damage occurs through focusing the IR on the retina which heats up.

Apparently the IR LEDs used in domestic appliances like TV remotes simply do not have the power to do that.
