How much value do you think it gives the end-user to change pantoscopic angle or horizontal angles on a progressive lenses. or to insert the reading distance, do you believe that it is important that the lens is PD optimized, it is very rarely I solve problems in my shop by giving the patient a more advanced lens. What are your thoughts on how to customize the best lens to your patient. Does any of you only make " Zeiss individual 2" kind og lenses to your patients ?
