Weak eyesight can often lead to misreading subtle body language and missing wedding proposals delivered via sky-writing. Sharpen sight in social situations with today's Groupon: for $250, you get $500 toward custom wavefront LASIK surgery at Joffe MediCenter. Surgery is priced at an already-reduced rate per eye ($495–$1,195), and customers may purchase two Groupons to receive a discount on both eyes.

Founded by a father-son team of vision enthusiasts, Joffe MediCenter uses advanced diagnostics and vision-perfecting lasers to reduce eyes' dependence on glasses and contacts. LASIK tackles nearsightedness, farsightedness, and astigmatism via an in-office surgical procedure, aiming to make formerly foggy blinkers bat with the clarity of a freshly polished invisibility cloak. Under the care of ophthalmologist Dr. Kenneth Smith, an experienced practitioner of laser eye surgery, patients receive an initial, free, noninvasive examination to determine whether LASIK is a good choice for their own orbs. First, Orbscan maps corneal terrain, flagging any squint-inducing asymmetries that can be smoothed out with LASIK. Next, the Zywave aberrometer, based on telescopic technology used to gaze deep into the eyes of the more romantic constellations, develops a three-dimensional model of complex eyeball innards. During the surgery itself, a microkeratome cuts a tiny flap in the cornea of the affected eye and lets the laser beam vaporize the tissue standing in the way of 20/20 eyesight. In most cases, you can accompany your revamped vision out of the operating room in about 20 minutes. After the procedure, the doctor will meet you for a postoperative exam.
