I think the issue is getting exaggerated. We have bars and clubs near the Chiang Mai airport (VTCC) which draw attention to their establishment by projecting lasershows in the sky being the airport within a 2 mile distance. I get struck all the time and I am more worried about fireworks getting into my prop than getting struck by harmless, low powered key chain lasers or even laser projections.
There are laser shows in the clubs crossing the visitors eye, too. Just the time of exposure to the eye is so short (and in an aircraft so much shorter due to higher speed) that it wouldn't harm.
There is no way anyone could keep a laser directed to your eye in an aircraft for a significant time so it could do harm. (At least not with commonly available lasers).
Everyone who doesn't believe it, go to a club with a laser show and see for your self.
Much a do about nothing. Again another way of making a dumb kid a criminal one.
