In my twenty-five years as an optician, Ive found that most consumers dont know how to obtain an effective pair of prescription glasses. They think that all they must do is choose a flattering pair of frames. Nothing could be further from the truth. For one thing, prescription glasses are not simply a fashion accessory; theyre a medical device. For another, its up to you and your eye-care provider to make sure you have the best vision possible. In the following pages, Ill tell you what to expect from eye-care providers and what your contribution should be. Remember, you only have one pair of eyes, and they deserve your closest attention.

A history of our time.
