Considering that present day plastic frames have undergone a fashion resurrection. Plastic is a very cost-effective and creative option for eyewear. Produced through an extrusion process, the plastic starts in a pallet form, goes into a hopper and gets melted and poured into sheets. This sheets form is often layered with others of varying colors to create a pattern.

In this method, the plastic is injected into a form or mold a molten and then cooled. (more eyeglasses…)
