Lesson Learned - money and time wasted on online glasses ordering
Last week I had one patient who learned about online glasses the hard way. He came in wondering why he couldn't see anything out of his new glasses that he had purchased online with his brand-new prescription. I had him put his glasses on, and I marked where his pupils were in the glasses. They were almost 1 centimeter LOWER than where the prescription was located. Poor guy, he was seeing through a place in the glasses that was 50% less prescription than what it should have been. No wonder he wasn't very happy! He learned that in certain prescriptions, it makes a difference whether you look through the top of the glasses, the bottom of the glasses, and in some cases, even the sides of the glasses. He said that the online order form just filled in an 'average' for the distance between his pupils, and that it put an 'average' for how high the bifocal line should be. Well, in order to see clearly out of your prescription, your pupils must line up correctly behind the lenses. In this case, we confirmed that the prescription was actually correct in the glasses, however, it was located in an area that didn't match his face and his eyes. This means that you must try on the frames to your face and make accurate measurements about where your pupils are in the frames. Sometimes, you get what you pay for! I have always been pleased by the customer service offered by LensCrafters, and I know they do an excellent job at making sure everyone's glasses are fitting them properly. Next time you get a glasses prescription, make sure it is accurately fit in the glasses frames as well!
