Seiko Surmount Lens Difference
 

Convex Add-Power Curve Technology
Surmoun’s newly patented technology is able to process complex convex curves onto the concave back surface of the lens blank. This technique, combined with advanced prism thinning calcula­tions creates lenses that are up to 25% flatter in plus prescriptions. The result is a noticeable difference in lens bulge when compared provides the best possible binocular near vision.

Optimized Automatic Variable Inset
Achieving point focus for near vision objects requires the inset of the reading zone relative to the distance to be precise. Surmount takes into account the wearer’s PD and distance lens power and calculates the precise inset needed to give clear binocular vision at the standard 35cm near vision reading distance.

Advanced Aspheric Compensation
Surmount uses advanced aspheric compensation to improve vision throughout the entire lens. Even in prescriptions with high cylinder, Surmount offers wider areas of clear vision than ever possible before.

Improved Performance for High Cylinder Prescriptions
This advanced compensation factors in eye rotation, vertex distance and the small changes in effective power when the lenses are tilted relative to the eye (pantoscopic tilt). It modifies the power in both the distance and near zones to achieve the optically precise correction for the as-worn position. The wearer experiences increased visual comfort, with wider areas of stable vision. This advanced correction also takes into account Listing’s Law, which governs the three-dimensional orientation of the eye and its axis of rotation. It provides proper eye to lens alignment in all direc­tions, significantly improving panoramic vision and image stability, especially in prescriptions with high cylinder.

Advanced Multi-Polar Astigmatic Correction
Oblique astigmatism and distortion in the peripheral areas of a lens force the wearer to constantly move his/her head to maintain a clear image. Surmount’s multi-polar astigmatic correction manages unwanted cylinder in all meridians, reducing oblique astigmatism. This creates a balanced progressive design that increases wearer comfort by reducing the need for head movements.
 

Advanced Material For A Custom Fit
Surmount is available in premium high index materials: 1.74 Clear, 1.67 Clear, Polarized and Transitions VI, 1.60 Clear and Transi­tions VI, and Trivex® Clear and Transitions VI. Transitions XTRActive® lenses are also available in 1.67 and Trivex lenses.

Product range is from +6.50 to -12.50, out to a -5.00 cylinder (refer to production range chart). Seiko Surmount lenses are also compat­ible with quality aftermarket AR coatings.
