Clinical study compares rotational stability of two differently designed toric soft contact lenses over a range of every day viewing conditions

"During wide angle eye movements, tasks such as scanning a newspaper for information, gazing to the extreme side for changing lanes while driving or parking/backing up, or trying to view a flag on a putting green while teeing off in golf, a rotated contact lens can greatly compromise vision, resulting in blur and a temporary loss of visual clarity," says study co-author George A.
