I ordered these specs with a lot of reservations but I need not have worried' they sorted out my prescription for me and the glasses arrived a lot sooner than I expected according to other reviews. I am very pleased all I had to do was tweak the nose pads slightly for a perfect fit. Yes they are a flimsy frame but for me they are just for use on the computer and work really well. I particularly like the rimless frame which I haven't used before and love them I am already planning my next buy from Select specs. Thank you so much.
