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— 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.

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.
