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.
