Laser visibility glasses PUA 60 The laser visibility glasses are not
protective glasses and thus do not
protect the eyes from laser beams.
As the laser visibility glasses restrict
color vision, they should be worn only
when working with the PM 4-M laser
tool. Do not wear the laser visibility
glasses while driving a vehicle on a
public road.
