What adjustment should be made if a patient complains that their frames sit too low?

When a patient complains that their frames sit too low, raising the bridge height is the appropriate adjustment to improve the fit and position of the eyewear. The bridge is the part of the frame that rests on the nose. By raising the height of the bridge, the entire frame is elevated, allowing the lenses to sit more comfortably and effectively on the face, which can enhance both aesthetics and vision.

Pantoscopic tilt refers to the angle of the lenses in relation to the horizontal plane. While adjustments to pantoscopic tilt can affect lens performance and alignment with the eyes, they are not primarily designed to raise or lower the position of the frame on the face. Similarly, adjusting the temple length affects how the frames fit behind the ears and does not directly influence the height at which the frames sit on the nose.

Thus, adjusting the bridge height specifically addresses the issue of the frame sitting too low, providing a direct solution to the patient’s concern.
