Acetate
A lightweight, durable and long-lasting material ideal for producing high quality frames. Derived from the cotton plant, acetate is naturally hypo-allergenic and less likely to irritate especially if you have sensitive skin.
Optyl
A heat resistant plastic which gives excellent surface finish and is higher strength than acetate. It's lightweight, flexible and adapts to the shape of the face. It's also hypo-allergenic and resistant to cosmetics.
Top Tip - don't use your glasses as a headband or they will lose their shape...even the peep team struggle with this one!
