ABSTRACT:
Optical light filters, useful for eye protection from laser radiation, are provided. The filter can absorb harmful radiation from lasers of several (at least six (6)) types which have a range of different specific wavelengths, yet permit sufficient visibility. A novel mixture of compatible absorbers in a transparent plastic carrier, having the required stability to withstand processing conditions and having satisfactory stability for use under environmental conditions is disclosed.
