Although vision is just one of five senses, it’s the one that tells us whether an approaching object is a friend carrying cupcakes or a puma who’s just ravaged a bakery. Keep danger in view with today’s Groupon: for $1,900, you get LASIK surgery for both eyes at Vision One Lasik Center, valid at locations in Rockford, Arlington Heights, Buffalo Grove, Lombard, and Chicago (up to a $4,400 value).

Vision One Lasik Center is helmed by Dr. Martin Burger, an ocular repairman with more than 65,000 procedures under his lab coat. He and his team of doctors employ the latest techniques to help correct a broad range of ailments, including nearsightedness, farsightedness, and astigmatism. Most procedures produce 20/20 results or better, reducing the need for glasses or allowing patients to quit their spectacles cold turkey. With a pretreatment exam and post-op visits, Vision One’s treatment includes total care by a doctor the whole way through, not a monkey in an adorable doctor costume. This Groupon also includes an enhancement warranty in the rare case that the procedure must be performed again. The LASIK surgery procedure is appropriate for most healthy pairs of adult peepers, and patients who elect not to receive the surgery will be fully refunded.

Though Vision One Lasik Center sometimes offers a discounted rate online, this Groupon still presents the best deal available.
