I wish someone could provide a good brick and mortar suggestion. The importance of purchasing properly fitting lenses from a B&M vs online depends on accurately measuring pupillary distance. I don't really trust the mail order places. The price of lenses is highly dependent on your prescription and type of lenses.
Im myopic as hell with a slight astigmatism, so I usually buy 1.74 lenses. They are as cheap as $350ish online, and around $500-600 in store. Id rather have the guarantee of a brick and mortar for something I use on a daily basis. My scratch coat lasted 4 years on my previous pair but only 2.5 years on my latest pair.
