Why is PD important in an eye exam?

When you wear eyeglasses like I do it's important that you get the best value from your eye-exam.


One way to get more value from your eye-exam is to purchase glasses from a company like ZenniOptical. My wife has used Zenni and loved the glasses, they make high-quality glasses and ships directly to you at home.


I know that they don't sell the high-priced designer frames, but they do offer great looking frames.


Why would you want to order a pair of spare glasses from Zenni?


Well, I go out railfanning and photographing a lot. When I do, I tend to be very rough on my glasses. They get put on my shirt neck, left in the truck, etc... this can quickly lead to scratches or other damage.


Having a high quality pair of "back-up" glasses can help save on the cost of replacement and protect your high-dollar frames.



The problem is that some eye-doctors don't want you to buy glasses from ZenniOptical or other mail order companies.


Those doctors make a lot of money off of the frames in the store. So if you ask for your prescription, they don't want to give you the PD.


The PD or Pupillary Distance, is the distance between the pupils of the eyes, center to center, in Millimeters. Without this measurement, you cannot order lens from companies like ZenniOptical.



I'm sorry, but when I pay for an eye-exam I believe that I have the right to get my full prescription. I'm paying for the service of the exam and for the results of the exam. 


Let me choose where I want to buy my eyeglasses from.

Vaucluse South Carolina Post Office

Vaucluse South Carolina, originally uploaded by Gene Bowker.

Maybe one of the "cutest" post offices I've ever seen. Vaucluse was a mill-town and the post-office was on the end of the millstores in "downtown".

There is a great millpond behind the office which originally provided water power for mills in the areas in the 1880's.

The mills have shut down but the town and post-office hangs on as a suburb of Aiken, South Carolina.
