MINERAL GLASS, NOT PLASTIC.
We're supplied by Barberini, regarded as the producer of the world's best optical quality lenses - famous for producing opticals for the likes of Maui Jim.
We use glass lenses, over cheaper plastic lenses for three key reasons:
Optical Quality - Mineral glass has by far the greatest optical clarity of all lens materials, with an Abbe value of 59 (vs. 32 for polycarbonate).
Sustainability - Recycled plastic lenses do not exist. Glass is infinitely recyclable, and doesn't produce microplastics when cut to shape.
Scratch Resistance - Our sunglasses are designed for the beach, which means sand - the enemy of most sunglasses. Our chemically hardened polarised glass is substantially more scratch resistant than other lenses, and exceeds all international impact resistance tests.
