All of the subjects had worn contact lenses successfully for more than six months prior to the thesis work,· many as long as six or eight years. Any subjective or objective symptoms differing from those prior to wearing the research lenses could have been considered the consequence of the new lenses. Many fitting problems can be overshadowed by normal adaptive symptoms, and thus, go unnoticed for a period of time, interferring with the subjective evaluation of the lenses. Given a contact lens with the same specifications as . those presently worn, (viz. optical zone radius, optic zone width, center thickness, power, peripheral curve width, and overall lens size), is there a peripheral curve radius, as determined subjectively and objectively, that seems to be ideal for the subject?
