What is the difference between conventional progressive lens and freeform progressive lens:

2.Customization
Freeform progressive lens is called Freeform because they can be fully customized. Manufactures of the lens are not limited by a fixed or a static design, but can fully customize your vision correction for optimal results. In the same way a tailor fit you with a new outfit, different personal measurements are taken into the account. Measurements such the distance between the eye and the lens, angle at which lenses are placed relatively to the eyes and in some cases even the shape of the eye. These enables us to create a fully customized progressive lens that will give you the patient, the highest possible vision performance.
3.Precision
In the old days, optical manufacturing equipment was capable to produce progressive lens with a precision of 0.12 diopters. Freeform progressive lens is made using the digital ray path technology software which allows us to manufacture a lens that is precise up to 0.0001 diopters. Almost the entire surface of the lens will be used for proper visual correction. This technology also enabled us to produce a top performing progressive lens that can be used in wrap-around (high curve) sun and sports eyewear.
