Like hardboiled detectives, prescription lenses clear up blurry mysteries and frequently end up framed. Focus on the facts with today's Groupon: for $39, you get $200 worth of fashion eyewear, sunglasses, or contacts at Saskatoon Optical Services. Clients may upgrade to $250 worth of products if they schedule an eye exam through Saskatoon Optical Services with a referred optometrist.

Highly trained opticians obligingly match customers to stylish spectacles, sun-blocking sunglasses, and discreet, comfortable contacts. Frames, such as the Gucci 2903 ($316) or Nike 8078 ($190), artfully encircle eye-parts, and perma-guard single vision ($98) or transition ($200) lenses repair broken optical projectors. A collection of contact lenses includes the conventional Optik Performance 59 torics ($130–$320) and the Biomedics one-day toric ($45/30-pack), which clears cloudy vision without the need for frames or nosepieces. With today's deal, customers may opt for an extra $50 toward frames, sunglasses, and lenses in exchange for sitting down for an eye exam with a referred optometrist or for correctly completing the secret-word find encoded into the eye chart.
