Advertisement Not putting this up for debate or dispute. Just some facts From P Edgeton, MS. Nuclear Imaging, MS. Imaging and Photometrics. Green Lasers are not to be considered safe whether direct or reflected light. Green lasers are extremely difficult to meter and limit the power output. The light commonly extends into the infrared spectrum. Only high quality green lasers with a certified IR filter should be considered somewhat safe and long term exposure has yet to be fully tested. Never expose yourself or any animal to the light. Direct and reflected green laser light is capable of damaging the retina and the eye is defenseless since IR light will not trigger protective reflexes.
