Pep674 named the grind style ( I had forgotten the term ) executive. This type of lens give the best peripheral vision availability. Does anyone know a competent lens shop that can make this lens type? Lens Craapers did a poor job on my first pair, the dividing lines being at different positions on each lens which is bad enough but they aren't parallel either. Aparently this is a type that is hard to make and thus has gone out of fashion either for this reason or vanity, there is no doubt that these are bifocals. Kent
