A boutique-style eyeglass shop whose proprietor travels to New York to pick up the latest frames, 20/20 Vision features chic mannequins that rock stylish eyewear, sun wear, and sports glasses pulled from designer collections such as Tom Ford and Vera Wang. The intricate designs of Roberto Cavalli sunglasses block out the nosy sun, while Maui Jam Punchbowl sunglasses trap rose lenses inside chocolate fade frames ($94.50).
