Even with strong additional power, the wearer can clearly view objects from a distance of about 1 m (100 cm) ahead when looking through the front of the lens. Ideal for those who do work, such as deskwork, within a small area of up to 1 m.
Even with strong additional power, the wearer can clearly view objects from a distance of about 2 m (200 cm) ahead when looking through the front of the lens. Ideal for those who do work, such as deskwork, within a small area of up to 2 m.
With ordinary progressive lenses, a common semi-finished blank(※) is used at each base curve division, resulting in differences in optical performance
Semi-finished lens material with shaping on one side completed, leaving the other side to be processed when an order is placed.
Indoor 100/200 provides a wider field of vision and comfortable fit to customers needing all kinds of power with no difference in optical performance caused by power.
Flexible Prism Thinning is carried out to achieve greater thinness and lightness of edged lenses to frame shapes.
The prism volume of Indoor 100/200 is set by each additional power with the balance between appearance and optical performance. The prismatic volume of the left and right lenses are automatically matched.
In this case, the prismatic volume is matched to the smaller value.
Clearer astigmatic field of vision.
Optimum aspheric correction is achieved using elements such as power, close work distance, base curve and the lens tilt angle in line with "Listing's Law" that determines the orientation of the eyeball when the field of vision shifts in upward, downward, left, right and diagonal directions.
Astigmatic field of vision wider by approximately 25%* *For S 0.00D / C-2.00D AX45°/ ADD 2.00D (P-1SY raito)
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. Indoor 100/200 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.
