The thing is, you don't need goggles if you are super-extra careful with it, are are very confident in your common sense.(I mean I personally now a few idiots with such a small amount of common sense that even if you warn them, then put them in a room with a highpowered laser, some of them are gonna get permanent vision spots in the first 5 minutes :
)
You know, in the end, we like green because it's bright....You're not gonna wear goggles all the time.They're especially good for burning, and while seting up stuff ...but you still have to take them off to enjoy the pretty shiny light once in a while
If we liked invisible beams and dots, we would use IR all the time instead of green with goggles.
I personally don't wear eye protection when I'm pointing (indoors/outdoors) , taking pictures, etc...I guess I know enough not to put my eye in that fricking bright line I see :
You just have to be aware of what can happen when you shine your laser at a particular object.If you can't trust yourself , then wear goggles, or don't get a laser
