Basic Info Before Using Laser Pointers
Safety using high powered laser pointers is a big concern among public and something that can’t be disregarded. Despite of its ability to burn and brilliant beams, these high powered laser pointers as well as portable laser are a danger to the eyes.
These pointers represent real dangers to the eyes.
