Reducing advertising or making the sale of higher-power lasers illegal won't help, because there's a very common source of high-power lasers: CD and DVD players. Both contain lasers that can cause eye damage, and they can be modified to produce even higher powers. The players that can also record are even worse, since they need lasers with still higher powers to handle the recording operation. Such players have long contained warnings on the inside not to overcome safety mechanisms or look at the laser, and the warnings are not just for show.
