asthenopia

Also known as eye strain, asthenopia is a condition characterized by nonspecific symptoms that occur after prolonged use of the eyes. These symptoms may include eye fatigue, discomfort, burning, itching, watering, blurred vision, headache, and occasionally diplopia. Asthenopia can be caused by various factors such as uncorrected refractive errors, accommodative or binocular vision disorders, prolonged near work, inappropriate lighting conditions, and dry eyes. Treatment involves addressing the underlying cause and implementing ergonomic measures to reduce visual stress.
