Rear Surface Progressive Lenses

Rear Surface progressives is an exciting new technology which enables us to customise the lens design for individual prescriptions and various frame compositions comparative to the limitations of traditional lens manufacturing which can only be tailored for a broad categories of wearers.

Fortunately, the individualized approach to Rear Surface Free form lens manufacturing ensures that every wearer enjoys the clearest distance, intermediate, and near viewing zones, eliminating the happy medium approach of traditional progressive lenses manufacturing, regardless of prescription or frame selection.

This technique originates by deciding on an ideal or target optical performance for the lens design for the given prescription. The actual optical performance can then be determined using computer ray tracing and lens-eye modeling, finally complex state-of-the-art computer generated algorithms map out the surface of the lens to achieve an optimized optical performance by minimizing the differences between the target optical performance of the design and the actual optical performance.



Free Form optimized prescription’s will ensure the widest fields of vision in comparison to traditional progressive lens manufacturing, as much as 50% larger viewing zones will be achieved with a Rear Surface progressive, this is illustrated in the picture below:



New manufacturing technologies allow for the full customization of progressive lens designs for each and every wearer, delivering consistent perfect vision regardless of prescription and frame selection. Our rear surface Varifocal design is optimised for each addition, for near vision, the lens also varies with the addition to maximise the reading area and improve the binocular vision.  There is a good balance between different visual zones to enable a smooth transition from far to near areas.

Thanks to its soft power profile, improved lens asymmetry and variable lens, the adaptation to our Rear surface Varifocal lenses are made easier compared traditional lens manufacturing, however progressives in general are not 100% successful either online or in the High Street, you should understand, there is a risk buying multi-focal lenses online and we cannot offer the after-service of the High Street, but our product is sold at a very competitive rate and we leave the choice to the customer.

Freeform rear surface Varifocals are about to revolutionize the eyewear industry as they will give clearer, wider fields of vision.  These lenses are available from as standard, Photo-chromic, Polarised, Super Thin 1.6 index, Ultra Super Thin 1.67 index lenses and Ultra X Super Thin 1.74 index lenses.
