What If My Pd Is Off

If my PD is moved by 2 mm, will it affect my vision?

The difference is between 2 or 4 mm.

Normally 2 closures would be acceptable, but 4 would be too tolerant for such a high power but the paradigm doesn't really matter.

If your DP is too tight, it will only provide a larger prism than specified, which is not a problem. If your DP is too large, you will have a smaller prism than necessary.

If you measure it yourself, it's probably too narrow because when you look in the mirror, your eyes meet.

Even if you are crazy, the fact that there is a mandatory horizontal paradigm will probably save you. That's the reason for the bad EP.
