For every 2 degrees of pantoscopic tilt, how should the OC be adjusted?

In the context of adjustments for pantoscopic tilt, it's important to understand that for every 2 degrees of pantoscopic tilt, the optical center (OC) of the lenses should ideally be adjusted to maintain proper visual alignment with the wearer's line of sight. The standard practice is to raise the OC of the lens by 1 mm for every 2 degrees of pantoscopic tilt. This ensures that the lenses are correctly aligned with the pupil, facilitating optimal vision.

Therefore, since the correct adjustment is not reflected in the choices provided, stating that none of the above is correct aligns with the accepted practice in ophthalmic dispensing. Proper occlusion adjustment is critical in ensuring that the wearer does not experience any visual discomfort or distortion due to inadequate alignment of the lenses relative to the eyes.
