2.11 PUA 60 laser visibility glasses
The laser visibility glasses have no protective function and thus do not protect the eyes from laser beams. As these
glasses limit color vision they must not be worn by persons driving on a public road and must not be used to look
directly into the sun.
The PUA 60 laser visibility glasses improve laser beam visibility considerably.
