Production Introduction
External progressive design: the progressive degree change process is made on the front surface of the lens. Contrast sensitivity is low, and it works better for people with poor backrotation. High Add or short channel using external progressive effect is better, but the field of view is smaller.
Internal progressive design: The gradient is made on the inner surface of the lens. The astigmatic region is relatively small, low Add or long channel is more suitable for this design. You can think of the lens as a window. The closer you get to the window, the bigger the field of view.
