I plan on either buying the krypton, arctic, or e3 laser from wicked lasers soon, and I need to clarify something about eye protection. The only time I will ever be using these lasers would be outside. If I was only shining the light straight up in the sky, would I need eye protection? Also, for a present, what is the lowest power green laser I would need to get to see the laser in the sky (not the dot, the laser)?
