The fit of the frame on the nose

The distance between the lenses

The forward tilt angle of the lens

‘Panto tilt’ refers to the forward tilt angle of the lens in eyewear fitting. This adjustment is crucial because it affects how the lenses align with the wearer’s eyes and influences both the optical performance and comfort of the glasses. By angling the lenses slightly forward, it allows for a better field of vision and helps prevent peripheral distortion, enhancing the overall visual experience. This tilt can also improve the frame’s aesthetics, as the lenses may sit more naturally in relation to the contours of the face. Proper panto tilt is especially important for progressive and high prescription lenses, where positioning relative to the eye can significantly impact visual clarity.
