Answers

Answered by khushidewangan012

Explanation:

Why lasers can cause eye damage. A laser's light is concentrated into a narrow beam. ... This can cause a detectable change (injury) to the retina, if the laser stays in one spot for a few seconds. This is why in some countries such as the U.K., laser pointers are limited to 1 milliwatt or less.
