Adaptive gait changes in long‐term wearers of contact lens monovision correction

Introduction:  The aim of the present study was to determine adaptive gait changes in long‐term wearers of monovision correction contact lenses by comparing gait parameters when wearing monovision correction to those observed when wearing binocular distance correction contact lenses.
