Lasers produce a concentrated beam of light which can cause permanent eye damage if viewed directly. Standard protective goggles block out a narrow frequency range which must be matched to the laser in use. However if the laser uses multiple wavelengths, or if these occur in the visible spectrum then the user may not even be able to see what they are working on.
These goggles can guarantee 100% protection for most class 4 lasers on the commercial market and protect eyes better against all direct or indirect radiation for longer periods and against higher power levels than established commercial laser goggles. Any exposure to dangerous light levels will protect the eyes of wearer. In the case of very high powered lasers the maximum damage would be to an easily replaceable camera.
