"Laser pointers whose radiation exceeds a certain level can cause serious eye damage. Their radiation is strongly concentrated and widens only slightly with increasing distance. With short distances to a laser pointer, it is therefore possible that a large part of the laser beam can penetrate...
It can cause distraction, being brighter than surrounding lights, within 4.5 miles (7.3 km) of the laser.The above calculations are for a 555 nanometer green laser pointer with a tight beam (0.5 milliradian divergence). These parameters are very conservative and thus result in the longest visua...
