For pilots, maintaining their natural night vision is a critical component for safe flight, especially during the vulnerable stages of takeoff and landing.

That’s why the dangerous increase in the number of laser strikes on aircraft is a big concern for aviation safety officials and pilots’ associations alike.

Last year, 590 laser attacks were reported in Canada. Most of them involved powerful green light lasers that were directed into aircraft cockpits. Once hit by a laser, pilots are temporarily blinded and experience immediate eye irritation, with the distraction impacting their ability to fly safely.
