Q: Trying to order glasses at 50% off. When I put a pair in the cart it gives me this error. This kind of item is only valid for one amount, or it will be recovered to the original price for the exceed pair.
Please tell me what this means, I thought it was for the PD numbers in which I had two but changed it to one and still received this error in the cart.
Awaiting your rapid response.
Thanks,

A: If you don’t have any PD values on the prescription, you have rights to contact your doctor/optometrist to get your accurate PD value.
Or you can measure it yourself with a millimeter ruler. Follow these simple steps:
1.) Rest a mm ruler on the bridge of your nose just in front of your eyes. Look straight ahead and line up the 0mm marker with the center or one pupil.
2.) Read the ruler in a mirror, or have someone at the same height as you read it.
3.) The mark that lands in the center of the other eye is your Papillary Distance.
4.) Repeat these steps 2-3 times to make sure your results are accurate.
