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. UJ2 features a lineup of 2 types of material: high index 1.67 material and 1.60 material. In addition, the lens uses the low base-curve UJ2 design. The combined effects of the material and design result in a lens far thinner and lighter than previous products.
UJ2 suppresses the magnified appearance of eyes produced by plastic lenses as well as changes to the face line to ensure no loss of natural expression.
