I have two numbers for my PD...
Don't worry. Some doctors take your distance for each eye. Your just a simple equation away from your pupillary distance.
1.Add the two numbers
The first step is to add the numbers together. We recommend a calculator because no one's perfect.
2.Divide by 2
Once you have the two numbers added together just divide them by 2 and that is you're pupillary distance!
Double check your number and then enter it in the pupillary distance field.
