Eye Focusing


A person’s focusing system, called accommodation, allows a child to see clearly, particularly up close.  Eyes are designed for distance vision, so when one looks at something up close, the natural lens in his or her eye has to change shape to redirect light rays on the retina for near objects.  Maintaining focus up close for sustained periods of time is important for reading, writing and also taking tests.  The ability to quickly shift focus when looking from near to far, such as when looking from the desk to the board is part of this skill.  For a child with accommodation problems, print will become progressively blurry as he or she reads for longer periods of time, and his or her eyes will fatigue from the strain of trying to keep the print clear. Sometimes children with focusing problems will develop headaches, hold their books closely or lay their heads down on a desk or study space.
