Which is the correct PD value for my prescription glasses?
For the reason that my current prescription glasses can no longer work well for me, last week i went to my eye doctor and have my eyes re-examined. Originally i tend to buy the glasses in the local shop so that i can try each pair and find the suitable glasses, but my wife told me that the prescriotion glasses sold in the online shops are quite cheao yet of high quality, i decide to have a try. before ordering, i feel confused about the pd value. It listed 65/62 in my script. Which one should i enter?
