Synergy WD features

The Synergy WD Series comprises 2 types

Balance-type "Synergy"

Synergy

The far, intermediate and near-distance fields of vision settings are balanced, making this the ideal lens for people using a progressive lens for the first time.

"Synergy WD" with emphasis on the field of vision

Synergy WD

Compared to the balanced type, this type provides a far-distance field of vision expanded by 18%. Although slightly inferior to the balanced type in terms of sensations of swaying or distortion, this is the ideal lens for customers used to wearing progressive lenses who place emphasis on features such as the width of the field of vision.

Synergy WD features short corridors of 10 mm, 12 mm and 14 mm.
For this reason, the lens can be neatly accommodated in shallow, an achievement difficult to realize with previous progressive lenses.

Thin, lightweight and comfortable to wear

  • Previous lens
  • 1.60 lens
  • 1.67 lens
  • 1.74 lens

This is an image of S-6.00. SEIKO's previous lens used 1.50 monomer.

The numerical value that indicates the ability of the lens material to refract light is called the "refractive index" and the higher this index, the thinner the lens. Synergy WD features a lineup of 3 types of material: Ultra-high 1.74 refractive index material, high index 1.67 material and 1.60 index material.
Synergy WD 1.74 in particular is 48% thinner and 35% lighter than previous lenses thanks to the synergy between the ultra-high 1.74 refractive index material and the inner surface aspherical design.
