When we think of Prada’s sunglasses, those ultra-modern geometric oval shapes are some of the most distinctive that rise to mind, and that’s the basis of its PR20VF sunglasses. Fitted with gradient lenses, the bold frames are sharpened even further to squared-off edges, and the tortoiseshell print contrasts with the glossy red acetate of the arms, which are each embossed with the Italian label’s branding.
