When used for good, lasers can correct vision, but when used for evil, they can undermine superheroes during important PowerPoint presentations. Fight the villainy of poor eyesight with this Groupon.

$2,699 for Bladeless LASIK for Both Eyes ($5,400 Value)

Surgeons correct nearsightedness, farsightedness, and astigmatism during a two-step process. First, an ultra-precise laser peels back a corneal flap. A second computer-guided laser then reshapes the cornea to improve visual acuity. The corneal flap is replaced and heals on its own without sutures, allowing patients to return to normal activities or slapstick routines in a few days. This Groupon covers the procedure as well as all preoperation consultations and one year of postoperation follow-up visits. If a person is not a candidate for custom bladeless LASIK for both eyes, they may be eligible to substitute service for custom PRK.

Clearview Vision Institute

Head surgeon Dr. Christoph Kranemann, who has thousands of vision correction procedures under his belt, leads Clearview Vision Institute’s team of optical professionals in sharpening patients’ eyesight. Understanding the anxiety often associated with visiting eye doctors, the staff quells unease by using the VisuMax system for more accurate LASIK procedures. Celebrated architects Diamond Schmitt have also lent their talents to designing a modern yet comforting environment. Light wood panelling and amber glass accents add warmth to white walls, and open spaces remove confined sensations. During procedures, ergonomically designed chairs keep patients cozy and reduce the need to shift or fasten seatbelts. The recovery room, lovingly dubbed “the spa,” features a row of leather recliners where patients can convalesce in quiet comfort or make eyes at the flat-panel TV.
