For offices that only do exams but don't sell glasses, is there a consumer guide to steer patients to help them select a progressive lens from the popular retail outfits they will go to, even if the quality snobs here might look down on them? Or does anyone here at least have thoughts on the lenses most patients will actually be choosing from? I'm new to this and don't know how the options compare. e.g. how does the Lenscrafter Signature HD lens compare to whatever Costco, Walmart and Pearle Vision Offer? How do the different Walmart high index lenses compare? (they have Zeiss, Seiko and Nikon among others, though I don't know what models).

For comparison purpose if you want one example, consider one patient with a high prescription and some difference between the eyes, e.g.:
O.D. -6.00 Cyl -1.50 095 Add +2.00
O.S. -9.50 Cyl -0.75 090 Add +2.00

Thanks.
