An all-purpose progressive lens suitable for new-presbyopes
HONGSUN OPTICAL progressive lens is an all purpose design that ouers wearers low distortion and a generous reading zone.
Available in in six corridor lengths suitable for a wide range of frames. Pre-determined corridor lengths for easy selection or computer selected based on the patient’s Rx, frame and face fit measurements.

What is a freeform lens?
A freeform lens normally has a spherical front surface and a complex, three-dimensional back surface which incorporates the patient’s prescription. In the case of a freeform progressive lens, the back surface geometry includes the progressive design.
The freeform process utilises semi-fi nished spherical lenses which are readily available in a wide range of base curves and indices. These lenses are accurately machined on the back side using state-of-the-art generating and polishing equipment to create the exact prescription surface.
• the front surface is a simple spherical surface
• the back surface is a complex three-dimensional surface
————————————-Freeform Design————————————-
Custom 14/16/18
The Custom 14 progressive is designed specifi cally for frames with small lens height (B size). This is achieved in a soft design without compromising the distance, corridor and reading areas.
Custom 16 successfully combines a soft design with wide distance, intermediate and reading areas. This design also
benefi ts from having low rates of change of mean power and maintains good dynamic vision throughout.
The Custom 18 design with its low rates of change and levels of astigmatism provides good dynamic vision combined
with generous intermediate and reading areas. Maximum astigmatism is located on the nasal side where most of it will be edged away.
