don't look into laser beam with your remaining eye

turns out those inexpensive green laser pointers can be a hazard.

however, one co-worker says it probably isn't as bad as they say it is. 1064 nm infrared light has quite a long absorption length in your flesh or braiiiiiin. he is doubtful that enough infrared light can be absorbed by your retina to cause permanent damage.

still, it could pay to remember the old maxim: cat toys are only fun 'til someone loses an eye.
