Acuvue Define were released early in 2008 and seem to have been
targeted at Asian customers, and they really only suit those with
darker eyes.
The lenses have a a unique and defined dark ring that enhances and
darkens the iris (the coloured part of the eye) thereby making the
eyes bigger, brighter and better defined. Two types: Vivid brown ring)
and Accents (black ring).
