UV protection, glare reduction, and contrast-rich vision are important to active outdoor wearers. However, on flat surfaces like the sea, snow or roads, light and glare reflects horizontally at random. Even if people wear sunglasses, these stray reflections and glares are likely to affect the quality of vision, perception of shapes, colors and contrasts. UO Provides offers a range of polarized lenses to help reduce glare and bright light and enhance contrast sensitivity, so as to see the world more clearly in true colours and better definition.
