The measurements of near PD, distance PD, seg height, vertex distance and adjustment of the frame prior to taking those measurements for a patient are the responsibility of our opticians. The opticians skill and knowledge adds to the value of the glasses and that is why you are going to pay more at an office (or even Walmart) vs online. The optician's services are built into the cost of the glasses, we do not charge separately for them. Internet retailers do not have the overhead that actual locations do, mainly because they do not bother to hire licensed opticians to help patients. Also, as you can see, the services received from them is much less.

The reason for hesitating on releasing PD measurements is because even small changes in those measurements from year to year can make big differences in the perception a patient will get from their glasses. It is interesting that many "e-retailers" will tell you that your PD will not change unless you are young. This is simply not true for everyone. Will it be close? Of course, but if you are off by 1 or 2 mm, it actually changes the prescription of the lenses in front of your eyes (This is why the E-retailer does not recommend taking your own PD). This can cause a list of problems like discomfort while reading, headaches, double vision, etc. If the seg height is off 1 or 2 mm, most people have difficulties with their bifocal even working. Different types of bifocals even have different seg heights.

When we release this information, we are assuming liability for your glasses being correct. This is why it is not part of your prescription. The prescription is the value of the lenses required to give you clear, comfortable vision. The optician selling the glasses is responsible for the fabrication of your lenses, not the doctor. If the lenses are not custom fitted to you, the prescription could be completely invalidated. Because of this potential service nightmare, we do not warranty our prescriptions in any glasses made online and we do not take measurements for people ordering online. I do not mind re-checking prescriptions, but I would not check the glasses made from an online retailer.

Online glasses buying patient, I'm very laid back and I just want to make sure you get what you need. I don't mind you getting your glasses elsewhere, but I would discourage online purchasing because of the lack of service you will get. Yes you would save money, but I'm sure you've heard the saying "You get what you pay for" I would recommend that if you are looking for a less expensive pair of glasses, consider using your lens benefit, which is given yearly with most VSP plans and ask about our budget line of frames. Or, if that is still too pricey, consider going to a discount location such as a walmart or sams club. Somewhere that has a knowledgeable staff member on hand that can ensure you are getting what you need.
