The photograph is an image that shows differences in fields of vision.
These are perfect for those changing from single vision lenses and wearing progressive lenses for the first time.
We recommend these lenses to those who have found it difficult to get used to and to use progressive lenses before now because adjusting the line of vision is completed smoothly.
Adjusting the line of vision has become smooth because sways and distortions are reduced, and the far distance field of vision is expanded.
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. Visio DS 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. In addition, back surface aspheric design is used to achieve a thin lens. The synergy between material and design of Visio DS 1.74 in particular enables a lens that is thinner and lighter than previous lenses.
