Wider about 2 cm! than my previous eyeglass however given size is 3mm larger only. (135 vs 138) The reason is that the holders are not considered in measurement and they are 1cm away from lens border on both side. Otherwise the lenses are perfectly put into the frame. Please give full width too not only the general size for your frames in the future. 1st pic shows the size difference bw my old and new eyeglass. it does not seem 3mm :(
