Ocular accommodation refers to how the eye’s ciliary muscles adjust and readjust the focusing system of the eye whilst maintaining clear vision.
Problems in accommodation that can lead to visual discomfort can be clinically measured by assessing its amplitude (maximal ability to focus), lag (accuracy of focusing) and facility (rate of change of accommodation).
This may have an impact on learning. For example, children with dyslexia were found to have lower median amplitude of accommodation than the age-matched control group and they are more likely to suffer from accommodative insufficiency compared to good readers.
Orthoptic vision therapy and spectacles may be prescribed by the specialist optometrist should there be an issue in ocular accommodation and/or binocular vision
