Abstract
The present invention provides new methods and systems for treating myopia progression in myopic patients who also exhibit near point esophoria, esophoria at near, eso fixation disparity, or eso associated phoria by selectively prescribing bifocal contact lenses to such patients. Near point eso fixation disparity may include esophores, low exophores, and orthophores. One method for controlling myopia progression comprises identifying a near point esophoric myopic patient, measuring an amount of fixation disparity, and prescribing a bifocal contact lens add power prescription. The bifocal add power prescription is based on the fixation disparity measurement and a distance prescription for the patient's eye.
