A conventional progressive lens
Frequently restricted vision zones
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.

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.

ILT
Impression - an individual
progressive lens
Maximum vision zones
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
ImpressionILT 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.
