"Ordered a pair of Prodesign Denmark off of Ebay. Had them shipped and after checking prices for the Prescription at Costco's, Walmart and Kaiser - he had the best price and quality, using Digital lens. The Tint came out better than I have every had, finally I get a darker tint in the Sun. Costco will have Digital in future but their progressive Hour glass shape is a one size fits all, they don't vary. Take a picture of them on your face and make marks, plus you will save a ton of money."
