Ask the independent optician if he or she can give you a break on a second pair. Do you have any vision insurance? Mine pays most of the cost of the glasses and there can be percentages off a second pair or off sunglasses, depending on the plan. Honestly, progressive lenses are not something to try to skimp on. Antiglare coating and lightweight lenses are important to me. Perhaps you could use less expensive frames. I've never purchased two pairs of glasses at the same time, but I do keep my last pair of glasses in case something happens to the newest pair.
