They provided me with faulty lenses where the coating got all crazed after only a week or so (was probably like that when I purchased but didn't notice until later) did not help in replacing, ignored me and since no office to complain to they simply ignored me!

Needing new glasses and finding most opticians VERY expensive, I found this site on the web. Their site is comprehensive and has easy to follow instructions. Got a copy of my prescription from my optometrist, entered all the details in the spaces provided. Chose the frames I liked from a wide choice and hey presto, new glassses for about a quarter of the price. I'd had quotes from between $ 600 to $800, these cost me $240. 00 and have all the features I wanted - multifocals, transition lens, semi - rimless frame in gold. You can see what they look like on a range of face shapes, print out an actual size pic of the frame to compare , and they can be contacted by email for queries and guarantee to respond within 24 hrs. - which they did !! A real answer from a real person. Amazing.
