We turned the concept of magnifiers on its head. Orvis Vice Chairman Dave Perkins had the idea to create a pair of magnified sunglasses that doesn't obscure your vision when looking down whilst wading or walking a stream bank. By placing the magnifier inset at the top of the glasses, your view of the water remains unobstructed. High-quality polarised optics for optimal light transmission on the water. In black, tortoise. Choose 1.5X, 2.0X, or 2.5X (go up from normal power when viewing through tinted lenses).
