These are just rare, one of a kind, Titmus Optical sunglasses, circa 1950's in great vintage condition.  Frames feature genuine Persol changeable / persolmatic glass lenses in excellent condition with no scratches, marks, or signs of wear.  These are probably first of it's kind, with high quality lenses showing Persol etching near the corners on both lenses.  Glass lenses get darker in color with more intensity to light.  They look to be grayish / brown in color depending on the amount of light transmission.  In addition, this item comes with an extra pair of vintage green shade glass lenses that were edged to fit this exact frame.  They are new old stock lenses, with no signs of wear or handling.  They're non-prescription, ready to wear.  Frames are 44-20 in size and also in good condition showing minimal wear when inspected closely.  There is some light shrinkage on the inside nose bridge, not visible when wearing.  A few, light, superficial marks on the paddle temples, seen under close inspection.  Nothing discernible.  No chips or tear.  Plastic nose pads are fully intact with some discoloration due to age.  Temples are straight and not spread apart.  Handles look good. Frames retain a nice sheen.   I would put the quality of these lenses right next to vintage Revo's and Bausch & Lomb Ray Bans.  These frames just rock.  All inscription is shown in pictures. They're 50 yr old frames that have been well preserved. 

Size:  44 - 20  5 1/8" across the front.  5" from inside temple to temple.  Lenses measure 1 7/8" in width and 1 3/4" (just short of) in height with 5 3/4" temples.
