A progressive lens easy to accomodate to, ideal for first-time senior lens users and users changing their lens prescription. The design provides a wide near-distance field of vision and clear long-distance vision.
In addition, 3 types of progressive corridor (12 mm, 14 mm, 16 mm) are available to match the customers lifestyle requirements.
*The progressive corridors of Wing 1.60 and 1.50 are 12mm and 14mm.

Little sensation of swaying or distortion

Wing Design

In addition to SEIKO's original progressive design, Wing makes use of the Wing design that incorporates an all-area asymmetrical design. The symmetry of the left-right long-distance zone of the previous design resulted in the potential for collective aberration on the nasal side that caused sensations of swaying or distortion.

The Wing design incorporates some of the aberration in the sides of the far-distance segment. This softens changes in aberration on the nasal side of the intermediate-distance zone to reduce sensations of swaying or distortion.

Additionally, as well as widening the far-distance field of vision, Wing ensures a near-distance field of vision. The smooth line of vision movement from the far-distance to near-distance segment makes this a lens that even first-time senior lens users can accomodate to with ease.

Lens appearance

Thin, lightweight and comfortable to wear

  • Previous lens (1.50)
  • 1.60 lens
  • 1.67 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. Wing features a lineup of 3 types of material: High index 1.67 material. 1.60 material and 1.56 material. Wing 1.67 is 40% thinner and 35% lighter than conventional back surface progressive lenses.
