For a direct hit or strong reflection your eyes would be better off with goggles.But since you get a 30mW you only get it for visibility, it's not enough to burn, so wearing goggles would make the visibility aspect pointless.Just be careful. Shining it in your eyes would cause instant permanent or prolongued damage(blind spots, partial colour blindness, insensitivity to green,....stuff like that)joe_black said:do you need safety glasses for a 30mw green laser? if i say did shine it in my eyes what would happen?
