Is LED harmful to the eyes (if one looks directly into it)?

Hi,

I have a led flashlight (Arc-AAA, 5.5 Lumens) and my child plays often with it. I know, LEDs are not harmful to the eyes. But can it be harmful if one looks directly into it? How bright can be a flashlight, so one can look directly into it without damaging the eyes?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
