Glasses prove invaluable in the wilderness, allowing one to start a fire or appear professorial while explaining man’s rightful place at the top of the food chain to ravenous bears. Always be prepared with today’s Groupon: for $50, you get $175 worth of prescription eyewear at any of Dr. Tavel Family Eye Care’s 20 locations. Today’s Groupon is valid only toward a complete pair of frames and prescription lenses.

With a medically centered focus, doctor owned and operated Dr. Tavel Family Eye Care updates exhausted eye fashions with stylish prescription spectacles. A wealth of lens types helps cut down on squint time, ranging from standard plastic to progressive lenses with upgrade options such as tinting and Teflon clear coating, which helps prevent scratches while providing a convenient nonstick surface for frying up silver-dollar pancakes. A team of talented opticians assists clients in choosing a suitable frame from a collection of lens-huggers crafted by top designers such as Fendi, Randy Jackson, and Lulu Guinness.

Watch formerly blurry blobs transform into cherished friends when viewed through a pair of basic frames with single-vision CR 39 plastic lenses ($99.98) paired with a premium collection frame ($50; $149.98 total). Dr. Tavel Family Eye Care also offers prescription sunglasses, including fashionable Fendi frames with polarized high-index lenses ($488.98) to shade eyes from harmful UV rays and provide a roguish air of mystique when worn after dusk. While vision insurance can be used towards an eye exam, it cannot be applied to the cost of glasses.
