Specialist Anti-reflective coatings

Our bespoke anti-reflective (AR) treatments on Diamond-Bio lenses combat reflections from external light and internal bounce-back, permitting up to 99% light transmission for high-definition vision. This multi-layered tech uses destructive interference to neutralise glare, easing eye strain when you're out in the sun.

Photochromatic adaptive tech

Because light shifts between different settings, our photo-chromatic lenses are built to automatically modify their tint intensity based on UV levels. They transition from lighter in the shade to darker in full sunlight, offering peak convenience and total UV protection.

Built for longevity

Hardcore scratch protection

Every Sunglass Fix lens includes a hardcoat for tough scratch resistance. Our Diamond-Bio range takes this further with an elite-tier hardcoat on bio-polyamide, providing incredible durability while remaining lightweight with the clarity of glass.
