“Double-side Progressive” + “Double-side Aspheric” Lens Design

N-style Wide and Smooth design

N-Style Progressive Both side–Maximum Clearly method
Aspheric Surface
New Flexible Inset design
12-level front curves 9/70 Addition setting

Retinal Focus design
Optimal Atoric design

N-Style Progressive Aspheric Surface
Plus-power lens Minus-power lens
For plus-power lens, deeper curve made on the near-vision
Shallower curve Deeper curve
area minimizes distortion shallow curve adjusts the far-vision
area. With this, a good balance between far and near vision
has been achieved.
(The opposite is made for the minus-power lens.)
Deeper curve Shallower curve

Bs-MC (Both sides-Maximum Clearly) method

The MC method that was adapted to “RESONAS” has been
introduced for the both sides of the lenses for further evolution.
With this, smoother & clearer vision as well as lighter & thinner
lenses have been realized, which is very close to a single
vision.
