Does my PD have to be exact? πŸ€”

Your PD should be exact. If your lenses aren't centered correctly, they can cause discomfort and eye strain. A small margin of error might not cause problems, but it’s better to be as accurate as possible. You can repeat the process a couple of times for accuracy and use an average for your final measurement.
