Abstract

As the general population grows older, the number of contact lens wearers becoming presbyopic is increasing. For many of these patients, bifocal contact lenses are a welcomed alternative to spectacle wear. The Tangent Streak Bifocal is a recent entry into the field of bifocal contact lenses, and is especially suited to patients who are former rigid lens wearers, and those who demand crisp optics at near and far distances. This clinical evaluation of ten subjects explored patient characteristics which allow the Tangent Streak Bifocal to best perform as it was designed, and also attempted to determine whether simple changes in lens parameters might affect lens performance in specific instances.
