Signature Range in now green (and red, yellow, blue, orange...)
These glasses are made from a resin sourced from soft-wood plantation timber called Cellulose Propionate.

For each two trees harvested for use in glasses, three more are planted.

Each kilogram of resin consumes 850g of Carbon dioxide (taking it out of the atmosphere) in an environmentally friendly manner.

Cellulose Propionate, like Acetate [Cellulose Acetate] used in many frames sold by your Optometrist, is a thermo-plastic. This means it become more flexible when it is warmed up without losing it's shape. This makes exchanging lenses easy and this range can have individual prescription lenses fitted for you by your optometrist.

These frames are made from injected polycarbonate. Polycarbonate is a widely used material in many fields as it is strong, light and hypoallergenic.

Polycarbonate frames feel light and take coloured paints and patterns applied in production very well to give good colourful results. Almost always, polycarbonate frames are provided with spring hinges. This is largely to protect the narrow ends of the frames and temples from fracturing under stress. Polycarbonate is a strong material but will fracture if pushed too far. Usually the addition of the spring hinge will be sufficient to guarantee a long and useful life.
