There is no need for high-output IR LEDs for this purpose. Thinking it isn't a good idea is different to there being actual risk of eye damage.

A quick search found this:

Which is a product that emits many times more power than the small IR LED's for our purpose.

Of course, if you can find documentation stating that there is a risk from looking at a 0.1W IR LED, then I'd be interested to see it.
