General EYE ADVICE

Fatigue

Lack of iron can also contribute to fatigue of the neuro-muscular system, giving rise to eyestrain and blurred vision. This problem is usually encountered less frequently as children grow older, with the exception primarily of some adolescent and young adult females who lack adequate iron intake. As a child grows older and develops a stronger neuro-muscular system, heavy demands on the visual system are less apt to produce the above symptoms of fatigue. However, excessive near work, especially many episodes of prolonged, constant close work, can lead to adaptive changes of the eyes.
