Nearsightedness impairs one’s ability to drive, read, and make the crucial distinction between truth serum and chocolate milk. Guard your secrets with today’s Groupon: for $50, you get a complete eye exam and a $100 credit toward prescription eyewear at Olson Eye Care in Waupun (a $185 value).

This Groupon is not valid toward nonprescription sunglasses or contact-lens fittings.

Olson Eye Care's adept optometrists build on more than 40 years of eye-tending experience to usher patients through comprehensive vision exams and eye-health evaluations. Ocular physicians determine a proper lens prescription with the aid of a refractor, which rotates an ensemble of lenses to test clients’ visual acuity at reading eye charts and a peacock’s subtle mating signals. If a prescription is needed, on-site optometrists pair patients with their ideal frames ($90+) based on facial structure and aesthetic preference. Patients can choose a frame to adopt from a variety of designer brands such as OGI, Armani Exchange, Kate Spade, and Oakley. Olson Eye Care also offers an extensive selection of children's frames, and fashions its glasses in an on-site lens-crafting lab to ensure an efficient turnaround time.
