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 would be considered in choosing the correct type.
BS-LARGO
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.
LARGO NEX
The NEX filter provides a wide feeling to both far and near vision by compensating the astigmatism for both. By combining two types of aspheric design- one for far and one for near.
