Eyeglasses correct vision, make people look more intelligent, and—when worn upside down—enable a dormant wad of gray matter in the brain to control the Hubble Telescope. Unleash your satellite-wielding capacities with today's Groupon: for $50, you get $150 toward a complete pair of prescription glasses or prescription sunglasses at Oregon Eye Specialists / The Sight Shop. Choose from eight locations in the Portland-metro area.

The Sight Shops operated by the Oregon Eye Specialists allow clear-sight seekers to browse a vast selection of designer frames such as Coach ($199+), Elle ($159+), and Armani ($259+), as well as a wide array of sunglasses by Oakley and Maui Jim. These frames boast enough flexibility to ensure proper fit and vision performance, but are also resilient enough to withstand the rigors of perpetual face hugging. To accompany their stylish frames, each Sight Shop exhibits high-quality progressive lenses in a variety of designs including single-lens, bi-focal, and tri-telescope helmet. The opticians at Oregon Eye Specialists—who are certified by the American Board of Opticianry—can help customers secure specific ocular solutions when assisted by a prescription from any physician. All frames and lenses carry a minimum one-year warranty.
