We have a more limited lens options range for Rimless Frames as certain lenses, such as 1.5 and 1.56 index lenses, are liable to crack with wear at the point where the lenses are mounted into the rimless frame. Polycarbonate lenses are the ideal lens for rimless glasses, but there is a limited prescription range for polycarbonates (see the 'Help with your Lens Options' section on any one of the frame pages below). 1.6 AR, 1.67 AR and 1.6 AR Transition™ lenses are fine as well.
