OK enough of this overreaction to anything the least bit "dangerous!" They are flashlights, NOT powerful lasers.
"LEDs are very bright. DO NOT look directly into the LED light!! The light can be intense enough to injure human eyes."

Notice the diagram? A typical 5mm LED.
Humans have a protective reflex but it doesn't work in all situations. Furthermore one of the first things any child is taught is not to stare directly into the sun.If we're going to become that concerned then you'd better make sure you send your kids out to play in welding masks because there's often on hell of a bright ball of light right up in the sky at noon that CAN damage your eyes.

I by no means shelter my offspring, many is the time I said walk it off, rub some dirt on it, man up and quit your whining, but the op's 3 year old infant/toddler should be guarded from any and all things that may cause injury. That IMHO is responsible parenting.
In most states to knowingly let an infant/toddler have access to anything that can cause injury may be considered criminal negligence, and/or negligence at a minimum.
