Circa 1970

This era in eyewear is one of my favorite periods. Manufactures realized that the time for small and classic was now all about Disco and Loud and Proud. Manufactures were developing new types of material. Many were of the large plastic sunglasses and eyeglasses were made of Optyl and injection molded. Titanium, Stainless Stell is also being introduced for the metal eyepieces.
