Why Laser Safety
LaserVision
The light from powerful lasers can be focused to power densities that are high enough to evaporate metal or ceramics.
Why do we have to be Protected from Laser Radiation?
Consequently, it is not surprising that laser radiation also can cut or destroy human tissue.
There is another potential danger : our eyes are particularly susceptible as they are much more sensitive to light, and it is possible to irreversibly lose one's eyesight with just one glance into a laser beam even with lower power.
