The graphics overleaf are representations of principles. A conventional progressive lens Frequently restricted vision zones Back Optimised for: standardised progressive surfaces the position of the lens in front of the eye -standard parameters Conventional progressive lenses have frequently restricted vision zones because optimisation is carried out using pre-fabricated progressive surfaces together with a standard position of the lens in front of the eye.

The graphics overleaf are representations of principles. Multigressiv - a power-optimised progressive lens Large vision zones Optimised for: lens powers the position of the lens in front of the eye -standard parameters Multigressiv provides large vision zones; some limitations can occur since a standard position of the lens in front of the eyes was assumed in the optimisation process. Back

Optimised for: lens powers the position of the lens in front of the eye -individual interpupillary distance -individual corneal vertex distance -individual pantoscopic tilt of the frame -individual face form angle The graphics overleaf are representations of principles. Impression ILT - an individual progressive lens Maximum vision zones Impression ILT always provides maximum vision fields since both the lens powers and the position of the lens in front of the eye is considered in the individual optimisation.
