I've ordered several pairs of glasses over several years. The results are mixed. One pair was good, one OK, one or two really not working. My main area of dissatisfaction is ordering progressive lenses... those are the multi focal glasses without bifocal lines. Distance viewing is typically very good; reading books or smartphone though, is a double vision experience. For those technically minded, the near-vision inter-pupillary distance is wrong, and it cannot be specified. Also they no longer offer the high refractive Index plastic. Another issue is obvious, namely, you don't know if the frame looks good or is comfortable until your glasses arrive. On the plus side, their prices are good and delivery is quick. Use them if you have a simple prescription.
