How to make an eyeglasses

I. Receive Rx and Measure Pupil Distance

n The interpupillary distance(PD) : the distance between the patient's pupil centers.

 
- So we can place the optical ceners(OC’s_ or MRP in the proper positions with the relation to the PD..

                      

 - Procedure
 . (Binocular PD) : Zero setting by left eye then measure PD by right eye.   

- Close/Open one eye alternatively
 . (Monocular PD) : by dominant eye / (near PD) for multifocal lens 

       
  Segment inset = (d-PD – n-PD) / 2

   - Close one eye and the other eye for measure.

 - PD represent examples: 64/60 – distance PD / near PD
 -   Corneal Reflection :

Frame Measurement : Boxing system STD Measurement of the Frame and Lens
