Deptrai,
I'd be very surprised if anyone onboard an aircraft had corneal damage from being shone on with lasers, unless they were disoriented as a result and stuck something into their eye.
Lasers are a serious matter for distraction and loss of night vision, but I'd say that the chances of retinal damage, much less corneal damage, from mW lasers that are at least hundreds of meters away without launch telescopes has to be small. The cornea evolved not to absorb visible light. To do eye surgery you need 0.1W laser flashes, all falling on the cornea.
Flaps,
Tell the police what you see every time - the beams are easy to spot and an alert cop next time might well be able to get a fix on the launch site. Any imaging from a police helicopter that could be within sight at the time could almost always locate the source to an address. They might even be able to get a decent idea of the location from dashboard camera footage from different angles.
