50-18-140 Metallic bug green metal frames by New Balance. New old unworn stock.. Low profile eyewear from the 1990's. Olive drab rubber temples. These feel really good. Semi rimless style.. Sturdy frame. Please read all the measurements below and compare them to a pair you already wear for size comparison.
Refer to diagram which shows you how to measure yours, it's where I measured these.
Just relying on your eye size NEVER indicates a sure fit. 
Space between the hinges is VERY important for a good fit too.
