I've never heard of a toy laser blinding anyone. If these lasers were dangerous they would not be sold to the public. You only have to watch the Spanish La Liga football on a Sunday night and everytime there is a corner, the forwards faces get hit with lasers. You don't hear the footballers complaining, and the players themselves cost about the same as a brand new 737.
