After I had already (still flash of light on the eye) tried other glasses (sunglasses, laser safety goggles from practice) without really good feeling I have now tested the light goggles and have to say that this is the best form of protection. Since one can not help when using the light pulse device to view, where you work just the flash of light with these goggles is no longer uncomfortably bright eye. I wear glasses, but you can even wear over my normal glasses.
