Possibly the new script and the frame style? Hands down the best specs I've ever purchased. I thought my TV was blurry and needed replacing, no, it was the eyes that needed an upgrade. A similar purchase from a well known competitor would have been three times the price. Many thanks, just love them.
Quick process and the ability to reorder without the hassle of prescriptions. My saviour during working from home. Great glasses have been repurchasing for years.
