Reduced glare, sharper vision

Anti-reflective lens coatings

Our bespoke anti-reflective (AR) coatings for Diamond-Bio lenses combat reflections from both light sources and internal bounce-back, allowing 99% light transmission for superior visual acuity. This advanced multi-layer tech creates destructive interference to cancel out glare, easing eye strain in bright light.

Adaptive photochromatic lenses for varying UK light conditions

Adapts to changing environments

Photochromatic adaptive technology

Light conditions differ between locations, so our photo-chromatic lenses automatically adjust their colour depth based on UV exposure. They lighten in overcast conditions and darken in direct sun, providing full UV protection and maximum convenience.

Durable eye protection

Ultra-tough scratch protection

All lenses from The Sunglass Fix feature a hardcoat for robust scratch resistance. Diamond-Bio lenses take this to a professional standard with an ultra-tough hardcoat layer on bio-polyamide, ensuring resilience while remaining lightweight with glass-like clarity.
