This Extra-vehicular visor assembly was worn by various astronauts during training sessions prior to the Apollo lunar missions of the late 1960s and early 1970s.
The A7-L Lunar Extravehicular Visor Assembly consisted of a polycarbonate shell onto which the cover, visors, hinges, eyeshades, and latch are attached. It consisted of two visors, one covered with a thermal control coating and the other with a gold optical coating. It had two side sunshields which could be raised and lowered independently.
This helmet was worn over the pressure helmet and fastened with a latch during EVA periods, and provided impact, micrometeoroid, thermal, ultraviolet and infrared light protection.
