Listing's Law governs the three-dimensional orientation of the eye and its axes of rotation. It states that, when the head is fixed, there is an eye position called

primary position, such that the eye assumes only those orientations that can be reached from primary position by a single rotation about an axis in a plane called

Listing's plane.

SEIKO’s NEW Free-Form Lens Technology benefits from multi-polar astigmatic SEIKO’s NEW Free-Form Lens Technology benefits from multi-polar astigmatic correction. This is calculated using SEIKO software taking into account eye rotation correction. This is calculated using SEIKO software taking into account eye rotation

factors as identified in Listing’s Law. factors as identified in Listing’s Law.

Distortion and oblique astigmatism in the peripheral areas of the lens force the wearer to constantly move their head to maintain a clear image. Prestige II manages

unwanted cylinder in all meridians, creating a balanced progressive design that reduces the need for head movements and increases wearer comfort.
