American Optical Alden Sunglasses vs Oakley Flak 2.0 XL

Buy the Oakley Flak 2.0 XL for sport, cycling, running or golf, where wide coverage, grip that holds when you sweat and swappable lenses matter. Buy the American Optical Alden for everyday wear and a classic square acetate look, with glass-like nylon lenses and a sturdier hinge. The Oakley has the larger lens and the stronger owner record; the AO is the better-built casual frame.

• Choose the American Optical Alden if you want a classic square acetate frame for daily wear, with a five-barrel hinge and a choice of brown, green or gray lenses.
• Choose the Oakley Flak 2.0 XL if you need wide peripheral coverage, a secure sport fit and the option to swap lenses for different light.
