There was once a fculty member fromCcolorado Sate University who lost part of his retina to a laser burn.

I don't remember all the details, but I think someone at CSU in Fort Collins, CO, might have an answer.

Just Google Colorado State University and ask for Environmental Health and Safety. Have lectured there and my daughter is a graduate. There's good folks there.
