Visual acuity is one of the most important functions of human eye. The Kinetic Visual Acuity (KVA) is movement-vision that is important for driving a car safely. Therefore, on the traffic safety education, not only needed to examine static visual acuity, but also checking kinetic visual acuity is required for aged people. Up to now, kinetic visual acuity equipments have some problems : (1) The reaction time related to kinetic visual acuity contains simple reaction time. Therefore, the measured value of kinetic visual acuity is not exact. (2) Mesopic visual acuity cannot be measured. In this study, we redefined the kinetic visual acuity and develop a new visual acuity equipment with multifunction based on the new definition of the kinetic visual acuity.
