Visible light transmittance: 15% VOLT+ The world's first polarized lens utilizing AI "VOLT+" was developed with the aim of achieving high contrast and color exaggeration for winter mountains, where many hard-to-see obstacles are hidden in a world that is almost entirely white. The development team utilized AI (artificial intelligence) to perform over 20 million combinations, resulting in the "Volt+" lens, which achieves the best balance of polarized function to suppress light reflection, high contrast, and color exaggeration. Compared to the scenery seen with the naked eye, the contrast and colors appear about 30% more emphasized. This allows the brain to process information more quickly than with the naked eye, leading to improved performance by rapidly processing various changes in conditions entering the visual field. ※Please comment if you have any questions. ※There may be scratches on the outer box due to storage.
