Goggles are never so you can point it in your face. No one wearing goggles should try that Ever. You ware them because a reflection can shot it into your eyes. 50mW can damage your eyes faster than you can blink, and on reflections it does the same damage. So yes if you are using the laser indoors at close range you should ware goggles. 1 reflection is all it takes and you could have the eye damage the rest of your life possibly.
That's false. Any good glasses should easily protect from a direct hit in their blocking region.
If you use OD1 glasses, then, yeah, maybe.
