Abstract

Method of supplying an optical lens adapted to a wearer, includes:

• • a) receiving, directly or indirectly via a manufacturing side, from a first networked computer entity located at a lens ordering side, a first set of data including at least wearer'"'"'s prescription data,
  • b) sending a second set of data including at least an optical lens design information and the wearer'"'"'s prescription data to a second networked computer entity located at a lens designing side, and receiving from the second networked computer entity a third set of data including at least optical lens data calculated from the second set, and
  • c) sending at least to a third networked computer entity, at a lens manufacturing side, a fourth set of data including at least part of the optical lens data, the at least optical lens data of the fourth set of data being at least partially modified by a masking function.
