Spectacles anti glare - aviators
More to this than meets the eye ( pun intended).
Your Avmed Examiner might put you straight on this.
I understand that aviation lenses must have a certain tranmission
level & be neutral grey so as not to affect depth perception.
The glasses that I know complied when I bought my pair (on advice from Avmed Examiner) were Bausch & Lomb G15 neutral grey.
