polycarbonate lenses

Polycarbonate lenses are made from a similar material to that of bulletproof glass, these lenses are 10 times more impact resistant than standard plastic lenses however this material is relatively soft, subsequently polycarbonate lenses need a scratch-resistant coating to prevent surface scratches.

Most other plastic lenses are made from a cast molding process, where a liquid plastic material is baked for long periods in lens forms, solidifying the liquid plastic to create a lens.

But polycarbonate is a thermoplastic that starts as a solid material in the form of small pellets. In a lens manufacturing process called injection molding, the pellets are heated until they melt. The liquid polycarbonate is then rapidly injected into lens molds, compressed under high pressure and cooled to form a finished lens product in a matter of minutes.

Polycarbonate lenses are thinner and lighter than regular plastic lenses. They also offer 100 percent protection from the sun's harmful UV light and are up to 10 times more impact-resistant than plastic or glass lenses.

Polycarbonate lenses are always recommended for kids glasses. They are sturdy and can stand breakage.
