Paige evelynFor all powers of progressive lenses to fit within a pair of eyeglasses, frames in the past had to be relatively large. If the frame was too small, the reading portion of the lens would sometimes end up uncomfortably small after the lens was cut to size and inserted in the frame. But lens manufacturers have overcome this problem by introducing "short corridor" progressive lenses with compact designs that provide larger reading zones for today's smaller, fashionable frames. so you just need to choose the frame as normal size.06/15/2012
