Neighbor Laser No filter

So my neighbor just picked up a 7W laser, and uses it in their garage across the street from me quite a bit for the last few weeks. I am just wondering, if I can see the blue part of the beam is there a chance I am hurting my vision? I am thinking about asking them to put up laser screens or something to block the light. I also am thinking about picking up a laser for the longmill, but I would wear glasses with it and keep the door closed so others dont have to see it.

Anyway, just wondering how safe this is and if I should go have a talk with them. As an aside, they dont even wear glasses at all around that thing which seems insane to me.
