@@hkn9739 That is simply not true. When using a higher powered laser it will produce much brighter light. The energy in that light can damage unprotected eyes. Even reflected laser light or indirect veiwing of the high powered beam is hazardous! Higher density/darker eye protection is required. I want to know what the experts recommend for a high power 7 watt laser.
