Having used Glasses Direct before, I was able just to update my prescription and confidently order the same size frames as my current ones. I would've liked to have a deeper frame size to accommodate bifocals but the frame sizes tended to be the same. However, for the money I am content to have what I've purchased. The process was very easy, the delivery was swift and the end result is a pair of glasses that meets my needs and no one knows what I paid for them! If they tried to guess, they'd be way out unless they knew where I bought them from!
