what is free form progressive lens?

Free-form technology virtually eliminates unwanted radial astigmatic error, the most common cause of non-adaption in patients with presbyopia. Traditional progressive lenses use one base curve to cover a number of prescriptions, which will correct power errors with a specific prescription, but yields a compromise with adjacent prescriptions within a given range.

Free form progressives are recommended for first time wearers of progressive lenses. They eliminate or reduce the distortion properties allowing more space for viewing channels.

Free Form progressives or known wide view progressives are recommended for people wearing progressives the first time. It has the ability to reduce distortion by wider viewing channel at the center of the lenses giving you a more comfortable eyewear with less distortion.
