Ray-Ban Wayfarer Oval Change are a new and unique style that will change the way you see sunglasses. These oval-shaped frames are designed for comfort and durability. The brown gradient lenses add an extra touch of elegance to these shades, while the polished waves brown finish completes the look. The light-responsive frame is made with photochromic dyes that activate in seconds under UV. The pigments change to reveal unique markings, and as the light gets stronger, so does the pattern.
