The best sunglasses ever caught on camera

Looking for sunglasses might not be your top priority with our rapidly shortening days, but a new book has got us thinking about our next pair. 50 Shades by American fashion writer Lauren Goldstein Crowe features a half-century of celebrities sporting stunning sun protectors. From Clint Eastwood wearing Wayfarers with his swim shorts back in 1956 to Robert Redford's mirrored shades captured by Ron Galella, the pictures show just how a pair of sunglasses can help you to blend in or, even better, stand out. Or, as Jack Nicholson puts it in the book, "With my sunglasses on, I'm Jack Nicholson. Without them, I'm fat and 60".
