Safe  practices and proper usage of safety equipment should be taken into  consideration when operating lasers. The eye is susceptible to injury,  even from very low levels of laser light. LP-LaserPair  offers a range of laser safety glasses that can be used to reduce the  risk of accidents or injuries. Laser emission in the visible and near  infrared spectral ranges has the greatest potential for retinal injury,  as the cornea and lens are transparent to those wavelengths, and the  lens can focus the laser energy onto the retina. Do not place laser beams at eye level.
