The Round, an early Ray-Ban icon, joins the Everglasses collection with photochromic lenses that shift from clear to gray as you transition between inside and outside, plus the added benefit of a blue-violet light filter. That means dual coverage in all light conditions. Round Clear Evolve with blue-violet light filter combines timeless design with quality manufacturing, to bring you an everyday accessory you never need to take off. Available with the archival Legend Gold lens logo.
