As a result, wear RayBan type aviator frame which requires an oversize
blank.

Have worn a photo gray lens for year which negates the requirement for sun
glasses, but does require glass lens and Corning is the only game in
town.


Is the glass because of the oversize requirement? Photo gray plastic is
readily available. I've been wearing Transitions for many years and like
the freedom from swapping to sunglasses.
