Pursuit EV features<Corridor Shifting Function design>

<Corridor Shifting Function design>
for a wide field of far-distance vision similar to that of single vision lenses

In many progressive lenses, the fitting point is the Additional power start-point and this results in sensations of swaying or distortion when the line of vision is shifted slightly from the frontal orientation.

In the Corridor Shifting Function design, the fitting point and the additional power start-point are separated to ensure a power stability area to achieve a sharp frontal line of vision. In addition, the power stability area and progressive corridor are optimally varied for each Addition to provide ease of vision and accomodation.

  • Ordinary progressive lens

The photograph is an image that shows differences in fields of vision. See the content of design below for a more detailed description of the design.

The fitting point and Additional power start-point are separated and the distance is reduced as the Additional power increases.

Comparison image

The progressive corridor is lengthened as the additional power increases.

This results in achieving a sharp long-distance field of vision and a supported near-distance field of vision.

Lens appearance

Thin, lightweight and comfortable to wear

  • Previous lens
  • 1.50 lens
  • 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. Pursuit EV features a lineup of 3 types of material: Ultra-high 1.74 refractive index material, high index 1.60 material and 1.50 index material. In addition, back surface aspheric design is used to achieve a thin lens. The synergy between material and design enables a lens that is thinner and lighter than previous lenses.
