Maybe you saw me post before about ordering eyeglasses from a site called Zennioptical.com. This site and other online eyeglass places are quickly becoming the preferred source for eyeglasses because of their lower cost, fast service, etc.
With the growing popularity of sites like ZenniOptical.com comes a growing trend for some eye doctors not to release your PD information. PD stand for Pupillary Distance and it is the critical measurement that online eyeglasses companies need to make you glasses that fit properly.
Have you ever run in to this situation from your optometrist? If you paid your money for an exam and the doctor refused to give you your prescription information, would you go back to that doctor? Would you pay for the exam? To me the eye exam is one service and the making of eyeglasses is another service. If I don't want my glasses made at the same place I get my eyes checked, then that is my choice.
I guess the best thing to do is to ask your eye doctor if they will release your prescription information, including your PD, before you get the exam. If they say no, then you have not wasted your money and can go elsewhere.
I can understand people wanting to make money, but the do not have the right to make you combine services if you do not wish to do so. I wonder if this trend will make some eye doctors charge more for the exam, or a fee for release of your information?
Like I said, ask questions BEFORE your exam.
