Surely not the Memory opticians in Amesbury; there was nothing worth steaming up from what I remember (no pun intended).
I got my glasses in BFTS and it wasn't until TWU where the sweat would drop onto the lenses where it became an issue; one skull cap later the prob was solved. That said, the glasses of the 80s and 90s were far from flattering, particularly for an aircrew ego and the phrase of 'better dead than bad' springs to mind.
Referring to the earlier post of Section Officer Harvey; I never really saw the attraction but that said, I went to develop an unending quest for female PBX operators so perhaps it was a subconscious yearning....?
