If you want to use these in an uncontrolled environment, definitely get the appropriate laser safety glasses (such as these) as well, and have anyone you don’t want to blind who are anywhere nearby or in line of sight close their eyes. Even the scattered reflection off glass or the metal of a camera mount can burn people’s retinas permanently, and depending on the surfaces it could scatter a few times and still have enough power to cause damage.
This means if a target is near a highway, you could blind passing motorists. If it’s near buildings, you could blind people peeking from windows.
Treat a 1W laser like a power tool. Amateurs can learn to use them safely, but you want to learn from guides rather than from mistakes.
