If a glasses wearer finds the bifocal too high, what is the suggested action?

When a glasses wearer finds the bifocal segment too high, it's important to address the fit of the lenses relative to the wearer’s line of sight. Increasing the pantoscopic tilt can help by angling the lenses closer to the wearer's face. This adjustment allows the segment of the bifocal to be positioned better with respect to where the wearer naturally looks, potentially improving their viewing experience without needing to remake the lenses.

The pantoscopic tilt refers to the angle between the frame front and the vertical plane of the face, influencing the lens position in relation to the eyes. By enhancing this tilt, the segment of the bifocal may effectively align better with the user's gaze when looking down, thus making the transition between vision zones smoother.

The other options suggest different changes that may not directly address the positioning issue of the bifocal segment as effectively as adjusting the tilt would. For instance, remaking the lenses can be more time-consuming and costly and may not guarantee alignment improvement without understanding the specific facial geometry. Increasing face form affects the lens curvature rather than segment placement, and angling the temples up focuses more on comfort and fit rather than directly resolving the height of the bifocal segment.
