The most coveted level of vision is 20/20, which means peepers can correctly identify 20 out of 20 typos on the optometrist's eye chart. Sharpen your natural spellcheckers with today's Groupon: for $29, you get a comprehensive eye exam from the Independent Doctors of Optometry at Sears Optical Center. Choose from eight locations in Aurora, Cherry Creek, Fort Collins, Littleton, Longmont, Thornton, and Westminster.
Located in Sears stores or at adjacent offices, Sears Optical's independent optometrists screen peepers to determine accurate prescriptions and diagnose any health problems. As doctors position a refractive device over the eyes, flipping through lenses of varying strengths, patients describe the level of clarity with which they can see the purple zebra dancing in the far corner. In addition to the prescriptive exam, doctors may use eye drops to dilate the pupil to scrutinize the retina.
