I was seated on the jumpseat on flight deck and the First Officer demanded I wear a face mask after pushback per policy; while they both (Pilot Crew Members) did not; which is inconsistent with Safety and general communication requirements requested of a Jumpseat Crew Member. Here is why:To ride on the jumpseat we must be a current licensed pilot; with current medical license and fit to perform duties.1. We are consistently asked to be a second set of eyes. Because I wear glasses where I wear my face mask my glasses fog up. I'm unable to see instruments and other traffic.2.The face masks impedes verbal communication with the other Crew Members if needing to intervene because the Crew is wearing headsets; jet noise and unable to effectively hear or read lips. This is well documented in studies.3.  The time to useful consciousness is limited. Having glasses and face mask impedes putting on O2 mask on in the event of a Rapid Decompression. The flight deck door is locked; we have NO rubber jungle that falls and I'm solely responsible for my own Safety to get my mask on. This is an impediment to Safety as a Jumpseater. I am not treated the same as the operating Crew Members; even though I'm asked to be a Safety Observer.
Air Carrier jumpseat pilot reported the First Officer on this flight insisted the jumpseater wear a face mask throughout the flight. Reporter described safety related concerns with having to wear the face mask including fogging of glasses; communication problems; and issues associated with putting on the O2 mask in case of a rapid decompression.
