Method of designing progressive lenses

摘要

A method and system for designing a progressive lens is disclosed. The method includes modifying a reference progressive lens design having a peripheral design which is suitable for a wearer and design features with known values. The modification of the reference progressive lens design provides a new progressive lens design in which at least one of the design features have been customised according to the wearer's preference. The new progressive lens design has substantially the same peripheral design as the reference progressive lens design.
