How can I mark or identify the width of the corridor from mid to all the way down to the reading area to draw the same window as they show on the catalogue. ) ( Or to put it another way, .. I doubt that I have been changed for wide corridor lens but actually they are ordinary narrow corridor,.. that is what mostly defined in catalogue or videos as wide reading field of view ... Just to be clear here I am not talking about length of corridor.. I did device a way, I wish I could share pics here .. by magnifying the fine net through the progressive lens and it will show the magnification according to the progression of the addition number, after drawing the outline on this progression I am able to get virtually the same curves ) ( but is it the right way to do it and challange the optician or the lens supplier?
