Patent

CA 2611515

A method for designing contact lenses is provided in which direct correlation is made between an individual's subjective assessment of the lens' performance with the objective measurement of one or both of on-eye lens position and eyelid movement. The method permits generation of lens designs that have enhanced on-eye stability in less time than conventional design methods.

La présente invention concerne un procédé de conception de lentilles de contact pour lequel une corrélation directe est établie entre une évaluation subjective faite par l~individu de la performance de la lentille et la mesure objective de la position d~une ou des deux lentilles sur les yeux et du mouvement de paupière. Ce procédé permet de générer des conceptions de lentilles qui ont une meilleure stabilité sur l~AEil en moins de temps que pour des procédés de conception conventionnels.
