Free Form Digital Progressive Lenses are Progressive lenses that are made using the latest technology in digital free form. This particular lens had many perks over standard progressive lenses giving the wearer maximum vision correction including distortion free sight at all angles and thus eliminating the key-hole effect other materials have viewing through them.
Digital lenses are created through a visual correction technique known as dual-surfacing which is progressive optics performed on both sides of the lens. Also referred to as free-form because the lens is customized to the patient's lens prescription in a very precise manner. This results in a more accurate individually customized prescription for the wearer.
