Review on Professional 190Nm 380Nm 600Nm 700Nm Wavelength Glasses by Mark Allen

Unlike other blue green laser goggles sold by this company, this red laser version completely blocks the wavelength, allowing you to see the dot can't see. You must be able to see the point to know where the ray is pointing. I contacted the manufacturer to find out why and please note that they no longer sell this version of the glasses on their website.
