Simplified way to find diameter for a single vision lens!

NB: In case of different PD in right and left, use mono ocular PD and double it instead of taking IPD.


  1. At step 1, the measurement on the picture is not correct, as well. According the picture the size is 62, but not 61.

  2. Thanks for correcting my mistakes in the picturisation. I have changed the picture as per the correct measurements.

  3. This is a great article, I have been always to read something with specific tips! I will have to work on the time for scheduling my learning.
