If you did not include your near vision PD, then it is automatically considered to be 2-3mm narrower than your regular distant PD. Example: if your regular vision PD is 63mm then your near vision will be 60-61mm.
Depending on the size of your frame and proper centering of your pupils to the lens such as adjusting the nose pads so that the frame sits centered with your pupils. A smaller lens size will have less a vision corridor than wider frame progressives, hence your eyes will make a quick convergence from regular to near vision than a a more gradual progression.
