*Every pair of LUUX sunglasses comes with polarised, CR39 lenses, the same optical-grade resin trusted in prescription eyewear for decades. Where many standard sunglass lenses can soften detail and add a faint haze, CR39 delivers crisp, true-to-life vision from edge to edge. It's naturally lightweight, around half the weight of glass, and resists distortion. This combination of quality lens and polarisation, means the world looks exactly as it should: sharper, richer and more natural. It's clarity you'll notice the moment you put them on.

The story behind CR39

CR39 takes its name from Columbia Resin #39, the 39th formula in a series of resins developed in 1940. It was first created for use in military aircraft, but its exceptional optical clarity soon caught the attention of lens makers, and by 1947 the first CR39 eyeglass lenses had been produced. More than 75 years on, it remains a trusted standard for quality lenses: lightweight, naturally resistant to distortion and remarkably clear.
