If the segments seem too low, which adjustment can be made?

When segments of bifocal or trifocal lenses appear too low on a patient’s face, various adjustments can be made to achieve better positioning.

Adjusting the nose pads closer together can help raise the height of the segments. This adjustment effectively alters how the frames sit on the nose, allowing the lenses to be positioned higher on the face.

Moving the nose pads down is another method that can also raise the segments. Although it seems counterintuitive, this adjustment can create a slight lift in the frames as the pads are lowered, which can raise the overall placement of the lenses on the patient's face.

Reducing pantoscopic tilt, which refers to the angle of the lenses relative to the face, can likewise influence the height of the segments. When the pantoscopic angle is reduced, the top portion of the lens is brought slightly inward, which can affect how low the segments fall.

Considering these adjustments collectively provides a comprehensive approach to addressing the issue of low segments. Each adjustment offers a viable solution on its own, and in some cases, a combination of adjustments may yield the best outcome. Therefore, all of these adjustments are relevant choices when segments appear too low.
