We have been having a discussion with some of our older Opticians (40+years in Optics) and lately they are angry about the amount of distortion/abberation that the new backside digitally surfaced SV blank lenses have at the fitting cross. If they move the lens "slightly" side to side the myers jump or become blurry. They said that if the lens is made from a SV blank, that anything at and above the fitting cross from one side of the lens to the other (horizontally/periph) the myers should be clear.
The only way I could think to explain why they are not 100% clear SV blank or not, is that the progressive design had to be put on the lens and there is still a corridor where the rx has to be manipulated to make that corridor clear for POW. Is that correct? They had pulled out a comfort2 lens to show how much "clearer" the myers were when moved. Yet when I look through and compare both the comfort and the digitally surfaced lens, the meyers on the comfot get distored at the very edges of the verification circle ( ) and on the digital lens its right outside of the circle, which tells me that the digital lens has just barely wider areas at the top.
Any other ideas how to explain that the digital lenses are a step up and not just all marketing hype? So far the public feed back has been fantastic. But the older Opticians feel like they are over charging for a horrible lens design.
