Not all sunglasses are created equal, and the subtle mathematics behind lens design dictate both your comfort and your vision quality. At BLANK, we prioritize lens technology, specifically utilizing the six-base lens curve in our most iconic frames. The Performance & Power of a six-base lens lies in its gentle, wrapped curvature which closely mirrors the natural curve of the human eye. This design minimizes peripheral light entry, reducing distracting glare and enhancing the protective coverage around the sides of your face. Unlike flat, four-base lenses which can sometimes cause minor optical distortion at the edges, the six-base lens provides superior, distortion-free clarity and a wider field of vision. When you demand peak optical performance, understanding the base curve is key—it’s the foundational technology that makes your vision sharper, clearer, and more comfortable, from the city street to the open highway.
