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. Outfit eyes for flawless proofreading with today's Groupon: for $49, you get $200 worth of prescription eyeglasses or designer sunglasses at Purba Vision. This Groupon is valid at locations in Brampton on Parkhurst Square, Ray Lawson Boulevard, and Father Tobin Road as well as in Guelph.

Purba Vision's savvy opticians stock the shelves lining each boutique location with designer frames and sunglasses and treat eyes to prescription lenses. A basic pair of house-brand prescription lenses and frames cure eyes in need of single vision ($160+) or progressive ($260+) spectacles due to sitting too close to the sun. Lonely heads find consolation in the gentle temple hugs of upscale eyeglass frames by Armani Exchange ($200 plus cost of lenses), and sunglasses by Prada ($350+) or Ray-Ban ($245) shield views on bright days. In addition to selecting designer frames from across the globe, each location has an on-site optometrist who can administer exams for an additional fee.
