Went here today pricing glasses and an eye exam. Previously since moving to AZ I have been using Walmart Optical. I was trying to find somewhere else to get my glasses.
Here were my impressions:
1. limited selection of frames, maybe half or less that of Walmart
2. high prices for exams and add-ons
3. very poor guarantee (only 30 days) Walmart replaced mine 13 months after I picked them up.
Here's how the prices ran: Lens, bifocal $180, Exam - basic $71, frame $130, 1 yr very limited coverage $40.
