What is a Pantoscopic tilt and why important on Varifocals?

Pantoscopic tilt is a position of wear measurement that affects how the lens is positioned in front of the patient’s visual axis in the primary gaze position.

What is the ideal angle for Pantoscopic tilt?

For every millimeter the pupil is positioned above the optical center of the lens approximately two degrees of pantoscopic angle should be applied to the front. Ideally, for good cosmetics, there should be approximately 8 – 10 degrees of pantoscopic angle for most frames.

How should glasses be angled?

The temples of the frame should be long enough so they can be bent downward at about a 45-degree angle at a point just beyond the top of your ears. About 30 to 45 mm of the temple should extend beyond this bend point and be adjusted to conform closely to the contour of your head behind your ear.
