Do I Need Safety Glasses Outside?

[FallOutFighter]

I ordered a laser from Survival Laser. It's 1,100mW and 445nm. For safety glasses I have an Eagle Pair that I will always be wearing when doing things like burning. When I am pointing the laser outside from a window at grass and trees should I wear safety glasses? If I don't am I taking any risks that my eyes will get damaged? I won't be pointing it at like cars or stop signs but does some light still get reflected from grass and other surfaces?

A laser that powerful I personally would never take the risk unless completely outside aiming at say a large tree 15ft+ away
