For $50, today's side deal gets you $200 toward a complete pair of glasses at Dietz-McLean Optical. This Groupon can be used at any of Dietz-McLean's six Texas locations. While the spec store doesn't offer in-house eye exams, customers can use their Groupon to get half off an eye exam with a partnered optometrist (normally $89).
