Principles Of Sportvision

The laws of sportvision propose that the primary visual skills for sport are aiming and anticipation, and based on this a formal programme of diagnostic and analytical tests has been developed. This includes measuring vision at both high and low contrast and importantly eye dominance.

This information is combined with tests for binocular vision (how the eyes work together), fixation disparity (how well the two images are processed in the brain) and a measure of refraction (short sight, long sight, astigmatism or a difference between the eyes).

The final consideration is a measure of colour preference and light sensitivity. Research has shown that colour preference is specific to the individual and is related to visual development. The use of coloured filters is a powerful new tool in the arsenal of Sportvision assessment. These filters are best applied after a full binocular vision assessment.

A series of analytical tests may then be conducted to measure, for example, reaction time or hand/eye co-ordination, as appropriate for the athlete and/or sport. In some cases these may be carried out as team assessments to allow comparisions of individuals against the norm.

The six diagnostic elements of visual performance are :

  • High and low contrast LogMAR vision
  • Eye dominance
  • Refraction
  • Binocular vision
  • Fixation disparity
  • Colour preference and light sensitivity

Your Sportvision practitioner is uniquely qualified to apply the results of your assessment and make recommendations from a wide range of specialist sports eyewear designed to address the requirements of your sport. This will also take account of any hazards associated with your sport to ensure that an appropriate level of eye protection is provided.

A programme of training exercises may also be recommended.
