Borderline too small.
I have a narrow face with 56cm/22in head circumference (crown may be different shape from yours) and needed/wanted a legit (these are real) pair of sunglasses that had a fitted look. My Von Zipper Lomax had a lens width of 57mm with a thick frame that went to the edges of my face. I knew the RB 3044 would be 52mm with a thinner frame and though I ordered sight unseen, they fit comfortably; Any smaller would be too small. There is definitely room around the edges that lets light in, yet going up a size is a (too large) jump in the wrong direction (for my face). Sunlight is filtered enough for my sensitive eyes and the temple length is long enough but at the limit of being too short. There also seems to be enough room behind the lenses for my longer eyelashes. No oil buildup from lashes is nice. The craftsmanship is nice, though I wouldn't pay full retail. IMO, sale prices are higher than the value/quality, but people pay so prices stay up.
