Amplitude lenses enable your eyes to make smooth, gradual movements when you change your focus from near to intermediate to far vision. Unlike bifocal lenses, Amplitude lenses eliminate the line that creates an abrupt, annoying vision change from near to far vision.
The next generation of Amplitude progressive lenses use the BKS backside free-form technology to allow for wide fields of view and are available in a vast variety of materials and colors.
