Featuring proprietary lens technology to improve contrast and Rapha's Freeform lens shape, the Letras offer a far superior fit than a traditional curved lens. The result is better coverage, with UV rays less likely to get behind the lens, and a wider, uninterrupted field of view for optimal clarity tuned specifically for cycling performance. The lens also features a hydrophobic coating to prevent water and mud sticking and the anti-fog and anti-scratch finish maintains a clear view for the long haul. \u003c\/p\u003e\n\n\u003cp\u003eWeighing a mere 28 grams thanks to the frameless design, the Letras sunglasses are barely noticeable when on while MEGOL™ arm grippers provide a reassuringly secure fit even in the wet. A choice of interchangeable nose pieces lets you tailor the fit and the strategically placed ventilation prevents overheating and fogging. \u003c\/p\u003e\n\n\u003ch3\u003eLens Specification\u003c\/h3\u003e\n\n\u003cp\u003ePhotochromic lenses adapt to light levels, darkening in bright sunlight and lightening in low-light conditions\u003c\/p\u003e\n\n\u003cp\u003eContrast-enhancing lens technology helps identify hazards and adapt to changes in terrain and light conditions\u003c\/p\u003e\n\n\u003cp\u003eMilitary-grade anti-fogging and anti-scratch finish\u003c\/p\u003e\n\n\u003cp\u003eWater-repellent hydrophobic coating\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eLight transmission\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003ePhotochromic lens - for variable conditions (dawn to dusk) - Category 0-3 transmittance\u003c\/p\u003e","brand":"Rapha","offers":[{"title":"One Size \/ Smoke\/Photochromic Lens","offer_id":54294295183706,"sku":"1862457","price":122.5,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/0827\/5290\/files\/Rapha-Letras-Photochromic-Sunglasses-Smoke-Photochromic-Lens.jpg?v=1781194676","url":"https:\/\/checkout.sigmasports.com\/products\/letras-photochromic-sunglasses-13x2v","provider":"Sigma Sports","version":"1.0","type":"link"}
