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 and coverage, to bring you an everyday accessory you never need to take off. Available with the archival Legend Gold lens logo.
