When should pantoscopic tilt be reduced?

Pantoscopic tilt refers to the angle at which the lenses of the glasses tilt towards the cheeks. This adjustment can affect not only the cosmetic appearance of the eyewear but also the optical performance, comfort, and field of vision for the wearer.

Reducing pantoscopic tilt is particularly important when the segments of multifocal lenses are positioned too low. This adjustment helps bring the segments into the optimal visual line for activities such as reading. When segments are correctly aligned with the visual axis, it improves the user's ability to utilize the reading portion of the lens without straining or awkwardly positioning their head to see properly.

In situations where other factors are present, such as lens thickness, width of the frames, or pressure from the temples, adjustments might be made, but they do not directly necessitate a reduction in pantoscopic tilt as a means to improve the alignment of the lens segments for the wearer's visual performance.
