Optimal Curve through Addition Power
A deeper front curve can be designed in proportion to the level of addition stabilizing back curve variations and minimizing sway and
distortions.

A new design introducing neuroscience and Maximum Astigmatism diagram
Clearly method has been integrated with the combined Conventional progressive lens RESONAS
Wide Area design, which was developed through
ergonomics. The zone with least aberration has been
extended by limiting natural aberration zones to the edges
of far and near vision.
Maximum Clearly method
In addition to the aspheric surface, a progressive surface
and aspheric lens surface with compensated degree have
also been mutually applied. The design of this idealized
aspheric surface produced a vision with clarity comparable
to a single vision lens.
