Yes but those glasses do not cover the entire range of laser light. You have to know what wavelength(s) you want protection from. I work with equipment that requires protection from laser light.
That is true. I’m thinking that the cops would go with a green wavelength laser (500~600nm?). The human eye is most sensitive to the green-yellow part of the spectrum, and a laser in that range would be the most effective at blinding someone without causing permanent damage. I would start their for a suitable pair of safety glasses.
