The Knowledge of Class 3A Laser Pointer Pen
A 4.99 mW Class IIIA green laser pointer beam can temporarily flashblind a pilot or driver, causing afterimages, within 530 ft (160 m) of the laser. It can cause glare, blocking a pilot or driver' vision, within 2400 ft (730 m) of the laser. It can cause distraction, being brighter than surrounding lights, within 4.5 miles (7.3 km) of the laser.
