OUR MINERAL GLASS+ LENSES

Optical Quality

ABBE VALUE: 59 vs. 32 for conventional plastic lenses

Mineral glass has by far the greatest optical clarity of all lens materials. There’s a reason why photographers use glass lenses: plastic mediums disperse and distort light. The optical clarity of glass lenses is measured with an Abbe value, with lower numbers representing greater dispersion and unwanted chromatic aberration.

Sustainability

RECYCLABILITY: INFINITE vs. plastic lenses not currently recycled

Glass is infinitely recyclable and is widely recycled. In comparison to plastic, optical lenses are made from virgin plastics, aren’t domestically recyclable and also produce microplastics when cut to shape.

Technology

REFLECTION FACTOR: 1.47% vs. 8.6% for un-coated plastic lenses

All of our lenses are equipped with an industry-leading anti-reflection coating on the inner surface of the lens, which eliminates distracting light reflections from light entering from behind the lens.

Scratch Resistance

MOHS HARDNESS VALUE: 6.8 vs. 2.9 for conventional plastic lenses

Chemically-hardened glass is more scratch resistant than any other form of lens by a huge margin. Waterhaul Mineral Glass+ lenses are designed to withstand the elements of sand and salt which come with adventure and deliver lasting performance.
