             Laby and Kirschen (2018) gave a new model        FUTURE OF SPORTS VISION:
          for sports and vision performance (see figure          The field of sports vision needs to incorporate

          sensitivity. These are included at the base of the
          pyramid. Visual acuity is improved by properly                                            DOMINANT

          sensitivity can be improved by means of filters
          and also by reducing glare in the strong light
          conditions of the stadium, monocularly. These
          come under the monocular sensory processes.
             The next level of the pyramid deals with the
          improvement in the binocular vision conditions
          wherein, motor problems such as strabismus
          and fixation disparity or sensory problems such
          as suppression and amblyopia are managed.
