SEIKO Surmount & Surmount Ws Free-Form Lenses

SEIKO Surmount & Surmount Ws Advanced Dual Patented 100% Internal Free-Form Technology



SEIKO Surmount and new SEIKO Surmount Ws 100% internal free-form progressive lenses are our most technologically advanced lenses. Their dual patented* design processes complex convex curves onto the concave back surface of the lens, permitting the use of flatter base curves on plus power prescriptions. The result is lenses that are up to 25% flatter in profile, even when compared to our other internal free-form designs. Wearers will enjoy the superior optical performance of 100% internal free-form technology, along with slimmer, lighter, more attractive eyewear.

 

Two Advanced Designs, Hard & Soft

Surmount lenses are recommended for active lifestyle wearers. Their soft design effectively reduces swim and sway distortion. They offer clear distance (40% wider) to the periphery, a smooth natural intermediate, and a wide, full power reading area. Surmount Ws (Wide & Short) lenses are preferred by those with sedentary lifestyles, who use their eyewear mostly for near vision. Its hard design provides a 42% wider reading area with clear distance vision to the periphery.

 

Variable Inset & Customized Optimization

Surmount calculates the precise inset placement needed to achieve point focus and optimum clarity at a standard 35cm reading distance. The ECP may further optimize the inset placement by specifying the wearer's preferred reading distance. Advanced Aspheric Compensation Surmount modifies the Rx to achieve an optically precise correction in the as-worn position. This compensation factors in eye rotation, vertex distance and frame tilt. The benefit to the wearer is improved clarity and visual comfort throughout the entire lens, with expanded peripheral vision, even in high-cylinder, high-add Rx's.

 

Multi-Polar Astigmatic Correction

Multi-polar astigmatic correction manages unwanted cylinder in all meridians, creating a balanced progressive design that increases wearer comfort. It takes into account the three-dimensional orientation of the eye and its axis of rotation and provides proper eye to lens alignment in all directions. This significantly improves panoramic vision and image stability.

 

Advanced Materials & Coatings For A Custom Fit

Surmount lenses are available in 1.50 and polycarbonate as well as in Trivex® and 1.60, 1.67 & 1.74 high index plastic in clear, polarized and Transitions® lenses. Transitions® XTRActive® lenses are available in 1.67, Trivex® and polycarbonate.
