Customer:
Hello, I was wondering how I get a P.D. I lost my prescription file and i only have my right # which is -0.5 (P.D. 32.50) and my left #-0.75 (P.D. 31.00). How do i determine just one P.D.? I hope that made sense.

KZFOO:
You can add the 32.50 and the 31 together. Or, when you input your prescription, you can add them separately.

Customer:
okay thank you!
