Asthenopia (eye fatigue)

Asthenopia (eye fatigue).

Stinging and pain in the eyes, tearing, redness of the eyelids and eyeballs, pain in the forehead, fatigue. All these are clear signs of the so-called asthenopia, often emerging in the computer users.

Asthenopia (Asthenopia; Greek. Asthenes weak + ops, opos an eye) — quickly coming eyestrain during visual work, especially at a small distance from the eye to the subject. Asthenopia— It is not a disease but a border state. However, if she did not pay attention, eye-strain can progress to a more serious disease. It is therefore important time to tackle this problem and fix it.


Typically, eye-strain appears in people who have to work long on the computer, or read a lot — books, brochures or documents. But not only that. The second necessary condition for the occurrence of asthenopia — different variations in vision: hyperopia, myopia, astigmatism or aging, because of which eye loses its ability to focus on nearby objects. Typically, such changes begin to appear after 40 years.

Distinguish accommodative and muscular asthenopia. Accommodative asthenopia develops as a result of fatigue ciliary muscle of the eye (the regulatory curvature of the lens) with its over-voltage (spasm of accommodation), and farsightedness, astigmatism. Weakening of the ciliary muscles of the body contribute to common diseases and intoxications.

Muscular asthenopia sometimes appears with congenital weakness of domestic direct eye muscles, but more frequently with uncorrected myopia. It may involve a breach of binocular vision and the development of strabismus.

What's going on?

Asthenopia manifested by so-called "visual" and "eye" symptoms:

  • blurred vision,
  • ghosting and blurring the image,
  • distortion of the shape and size of the observed objects.
  • inflammation of the eye,
  • lacrimation,
  • eye fatigue, increase their temperature,
  • discomfort, pain, cramps or burning of the eyes.

Diagnosis and treatment

The diagnosis is based on typical ophthalmologist complaints and specific examinations. In most cases, at the same time revealed far-sightedness, myopia, astigmatism or weakness of the ciliary muscle.

For the prevention and treatment of asthenopia necessary restorative therapy, timely correct the correction of hyperopia and myopia of view of hygiene, proper work-rest cycle for the eyes.
