Abstract
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.
