Surface Controlling design

It enables the wearer to widen middle vision without affecting the comfort of the reading vision.

For far vision

SC has a smooth curved surface and removing the remaining aberration to the extreme sides of the far vision field has reduced distortion.

From middle to near vision

SC provides a comfortable middle vision because its design is changing gradually the rate of power in the middle part, and ensures 70% for a natural and comfortable middle vision. According to the monitoring results, by experienced progressive lens users over the age of 50, it has been proved that the eyes turn to the point, which is 9mm downwards from the far vision area. In addition, SC provides a wide and clear reading vision field.
