50-18-140 1950s TITMUS Z87 Safety Glasses Mid Century Vintage Near Sighted Rx

50-18-140 1950's very worn, dull horn rim safety glasses with super clear glass bifocal lenses that offer strong distance magnification for near sighted people. Will fit an average sized adult head. Very good vintage condition. These lenses make your eyes look smaller than they actually are. Please read ENTIRE DESCRIPTION. Acetate is very good (No shrinkage). Tarnished barrel hinges, they're tight, and can't be tightened. The temples swing easy and these glasses cannot fold completely flat like normal glasses because the shields are in the way. They will fit in a draw string pouch I provide with your order. The shields have yellowed and awkward to clean. I put these in my ultrasonic cleaner several times and got them as clean as I could. Right lens has some sort of solvent on the outer lens perimeter that I can't clean off. Shouldn't affect your vision. Frame is very dull and could be polished. Just don't have it in my hands to polish and restore these babies.... Frames feel great. Dense plastic that feel good when you hold these. Compare your numbers to mine for fit. Measure your frame width and inside hinge to hinge as well. *****SPECS***** Frame width: 5 1/4" (134mm) Frame height: 1 3/4" (45mm) Frame material: Nylon Lens width:1 15/16" (50mm) Lens height: 1 11/16" (43mm) Hinge to hinge width: 5" (127mm) Key hole Bridge (DBL): 18mm Temple 5 1/2" Spring hinge: No PD distance: 2 1/2" (65mm) Lenses: glass/distance bifocal
