Other Progressives

Lateral power errors
Progressive lenses have two lateral areas that do not offer wearers optimal vision. These areas arise due to lateral power errors caused by the combination of two components: cylinder power and sphere power.

Camber Steady

Superior lateral vision
“Steady technology uses a strict control of the mean
power that practically eliminates the spherical error in the lateral areas of the lens. Thanks to this improvement, a significant reduction of the maximum astigmatism lobes is achieved, offering the wearer an improved lateral vision with superior image stability.”
