Laser pointer causes eye injuries?!

Laser pointers were banned in a Wisconsin public school district after a teacher and student “suffered serious eye injuries.¹ ” A female student reportedly could no longer see the color red in one eye, and a male teacher reported serious vision loss in one eye as a result of direct ocular exposure to the laser beam. Laser pointers are available from many vendors and are commonly used in educational institutions and industry by persons who have little understanding of the potential for laser injury. The results of further investigation into this particular incident will be presented.
