Veteran optician weighing in… I’ve done the retail thing (Pearle Vision Center, WalMart Vision Center), and I currently work in a privately-owned ophthalmology based practice.
I’m VERY picky about my own glasses. Eyewear is my business, and mine had better look perfect on me. As I get an awesome discount, I have several pairs, all of them “name brand”, but no Prada or Versace for me (even discounted, I just can’t bring myself to pay for them). My current 3-pair rotation includes one Vogue and 2 DKNY. New Vogue has been ordered, and will create a 4-pair rotation, even though they will be worn rarely due to their, um… unique color.
For the most part, unless your prescription is as complicated as many have indicated above, buying glasses online should not be too much of a problem. ANSI provides us with standards that must be met, and all opticians have the same “rules” to follow.
As far as fit goes, you really can’t go by your current pair and expect a frame of the same size to fit exactly the same way. My glasses range from a 48 to 54 eyesize, and every single one of them is a perfect fit, ON ME. One major concern with fit is the bridge on zyl (plastic) frames. If it doesn’t fit your nose, I can’t make it. However, frames with adjustable nosepads can be tweaked by any optician. We have groovy tools (literally, a plier with a groove!).
I am NEVER offended when a patient tells me they want to take their Rx to Walmart or wherever. My budget is limited too, and I don’t begrudge anyone their savings. And yes, I will gladly pop your eyewear onto the lensometer and double-check the prescription for accuracy. And I adjust eyewear purchased elsewhere almost as often as I adjust eyewear bought from my office.
Bifocal wearers, of course, will have more trouble buying online because of seg-heights and optical centering on progressives. But any optician can give you your PD. In fact, just today, a former employee called to ask her husband’s PD so he could order a pair online!
My only advice would be to check “patient satisfaction” policies, and the retailer’s policy on doctors’ rx changes.
Yes, own several pairs, so you can change them with your mood! How many people own 20 pairs of shoes? Nobody looks at your feet! Own more specs, because people almost HAVE to look at your face.
