Lesson_10_OAO

The evaluation, compensation and training of visual skills as well as visual protection and prevention system against ocular trauma, in order to enhance sport performance, or globally sports vision, is one of the most attractive competence of the future and current optometrist.

This field of the visual ergonomics, or environmental and occupational optometry, requieres to study the visual skills (following the Welford’s model) related to different sports, both collective and individual, with or without ball, tool, indoor vs. outdoor, etc. Only in this way, it should be feasible and efficient to evaluate them applying conventional and non-conventional optometric and psychophysical tests, in order to plan, adapt (following the sports vision pyramid) and monitor (with useful feedback) at qualitative and cuantitative levels different visual training activities, both for professional and amateur users, even young, adult or older.

Any visual training implemented in sport should be followed some general principles:

  • visual demands: distant vision always compensated;
  • visual ability: from isolated to integrated;
  • visual skill: from basic to complex;
  • simultaneous distractions / demands and cognitive processes
  • fast movements and reactions
  • non primary gazes or equilibrium positions
  • fatigue effect: phorias ­, visual field, VA , reaction time
  • etc.

Other issues interesting for any expert in sports vision can be those focused on the environment, as the lighting design, or eye protection, or even visual training by videogames, or applying neuroergonomic devices and visualisation tools.
