I expected they would be staggered - I hadn't thought about the one near, one far process. And when I had prescription sunglasses made I had to change glasses to see the phone, map, etc. so the second pair had bi-focals. I'll have to think about this. And of course once I do have the surgery I'll need different glasses. I think it means the next pair of glasses won't have all of the bells and whistles because they'll be replaced in a few months. I suppose it's possible to get glasses with no prescription on top but the bifocals below. Those would work for driving.
