Most (all?) Lenscrafters have an Eye Exam 2000 doctor's office next door or inside -- technically a separate company, but no one is fooled :) A basic exam will cost about $40 up to $100 if you get retinal photography, etc., but it probably varies from place to place. Real docs of Optometry, too, although a technician will do the pre-exam stuff.

But you can bring any prescription into Lenscrafters, or vice versa. I go to my regular Eye Exam 2000 doc (she's great) and then take my prescription down to Pearl.
