Even moderately powered lasers can cause injury to the eye. High power lasers can also burn the skin. Some lasers are so powerful that even the diffuse reflection from a surface can be hazardous to the eye. Diagram of a human eye. The coherence and low divergence angle of laser light, aided by focusing from the lens of an eye, can cause laser ...
Laser pointers, even those sold for less than $20 online, can distract pilots or cause flash blindness — of particular danger during takeoff and landing, when many incidents are reported.
