If the segment of lenses appears too high for the wearer, what action might the dispenser take?

When the segment of the lenses appears too high for the wearer, angling the temples down is a practical action that may remedy the issue. When the temples are adjusted downwards, this has the effect of lowering the fit of the frame on the wearer’s face. As a result, it can help bring the segment of the lens into a more suitable position for the wearer, allowing for optimal vision through the reading segment. This adjustment is common in optical dispensing practices when fitting progressive or bifocal lenses, as alignment is crucial for comfort and functionality.

The other options do not address the problem as directly. Angling the temples up may further elevate the frame, worsening the perceived height of the segment. Increasing the temple spread angle could potentially create a looser fit that doesn’t help with segment positioning. Similarly, decreasing the temple spread angle might cause the frame to pinch on the sides of the face or affect overall fit without lowering the lens segment. Adjusting the temples down is a focused approach to ensure the lens segment is positioned correctly for the user's viewing needs.
