It is the inability to sustain binocular function while doing close tasks like computer work, reading, or writing. Usually, one of the eyes drifts outward when focusing on a near object or a word. The condition arises from fatigue due to close work in vulnerable people; it is not a muscle defect. It commonly occurs in school-age children and adolescents, causing double vision, eyestrain, headaches and difficulty reading. Often, teachers and parents mistake it for a learning disorder.
