The most coveted level of vision is 20/20, which means peepers can correctly identify 20 out of 20 typos on the optometrist's eye chart. Engage in pupil proofreading with today's Groupon: for $47, you get an eye exam (a $95 value) and $200 toward the cost of prescription single-vision lenses and in-stock frames at Urban Optik (up to a $295 total value).

Inside a sleek eyewear boutique, Dr. Annu Kaul and her band of optical pros thoroughly examine eyes before customers visually feast on a dazzling variety of frames and lenses. A 30-minute exam goes beyond the typical prescription fine-tuning as Dr. Kaul evaluates overall ocular health, checking eyes for cataracts, chronic glaucoma, and stoic stares into the distance. With prescriptions determined, staff members help customers sift through single-vision lens and frame choices from designer brands such as Ørgreen, Lafont Paris, and BOZ Eyewear. Maintaining a schoolyard-chic assortment of children's eyewear, the service team at Urban Optik can help miniature humans pick out and fasten training wheels onto a selected pair of kid-friendly specs.
