In nature, the only way for animals to achieve perfect vision is to crossbreed with an eagle, usually resulting in eagle-eyed abominations such as snakes with talons and flying pumas. Keep human senses sharp with today’s Groupon: for $50, you get an eye care package from Dr. Wagner’s Southridge Optical (a $180 total value). Each package includes the following:

• A comprehensive eye exam (a $30 value)
• $150 toward prescription eyeglasses

The eye experts at Dr. Wagner’s Southridge Optical remedy blurry vision with prescription lenses fitted into more than 1,000 styles of brand-name frames. During a comprehensive eye exam, Dr. Wagner runs peepers through the gamut, assessing eye health and calibrating prescriptions with high-tech equipment, multiple stages of testing, and retinal photographs. Afterward, the optometrist guides visitors through lens options that can solve near- and-farsightedness and help wearers to differentiate between their mailboxes and the family dog. Clients then select face-flattering frames by such designers as Coach ($179.95– $319.95), Versace ($199.95– $529.95), and Harley Davidson ($159.95– $199.95). Prescription eyeglasses are typically ready for pickup in about a week, so in the meantime, clients should string together temporary glasses using Coke bottles, superglue, and glitter.
