Why We Need Good Focusing Skills

Eye focusing (technically called accommodation), allows us to see clearly at different distances.  Our eyes are designed to focus only at one distance at a time – so when looking close, far images will appear blurry and when looking far, near images will appear blurry.

How Focusing Works

Our eyes are naturally designed to be clear for distance, so when we look at a near object, the lens in our eye changes shape to redirect light rays on the retina (much like a macro lens on an SLR camera).  For near tasks, more effort is required to maintain a clear, sharp image for a sustained period of time.

When Our Eyes Get Tired

Sometimes children with focusing problems will find their eyes fatigue very quickly and can no longer maintain the effort.  When that happens, their vision at near can flicker between clear and blurry causing watery eyes, excessive blinking, eyestrain and headaches.  Some children may avoid reading by this stage whilst others will continue to try ‘hard’ and may hold print very close when reading.

Focusing problems may be diagnosed as:

  • accommodation insufficiency
  • accommodation excess
  • accommodation infacility

The Symptoms To Be Aware Of

  • hold things very close
  • complains of blurry vision
  • poor reading comprehension
  • says eyes are tired
  • able to read only for a short time
  • has headaches when reading
