Examples for selection

“LARGO” has 2 types of digressive power. The width at hand and perspective depend on the type. The remaining accommodation range of a customer shall be considered for choosing the type.

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.


The NEX filter provides a wide feeling to both far and near vision by compensating the astigmatism for both far and near vision by combining two types of aspheric design each for far and near.
