As with any other professional, try to get referrals from others regarding a particular optician. Friends and family will usually be glad to help, and you might find that someone has provided a thoughtful review of their service online somewhere.
One way to check on a particular optician's reputation is to contact your local Better Business Bureau. They'll be happy to let you know if there have been any complaints against that person, though they won't tell you much more than the basics.
If you're worried, check to see how many years of experience your optician has, particularly with your kind of eyewear or optical problem. If necessary, ask to see their license; in most states, a license is required to dispense eyewear, although there are a few exceptions.
"What is an optician?
Eye glass centers are professional managed facilities, which traditionally provide corrective lenses for vision.
Why do you look for one?
If you need a place:
» To provide you with new glasses,
» To fix the glasses that you already have,
» To give you the new look you want,
» To provide you with the vision correction you need,
» To give you the style of glasses you are looking for,
then you look for an optician.
