Assuming sale/possession of a laser that strong is illegal in the US, ALPA or some interested group might very inexpensively have at least a small impact by having their legal people send letters reminding eBay et al of the issue. Beyond that, what to do? US Customs is too busy to interdict (these are surely Asian sourced), and the perps are either malicious or ignorant of the potential consequences to their target or themselves.
Interestingly Wikipedia says the high-powered green ones are based on IR diodes and retain a large IR component so goggles (or cockpit-window films) would need to take that into account since the invisible IR component is damaging too.
