Astigmatism is an eye disease, but a deformity of the eye that makes the best vision. The incidence is equal in men than in women, these women who come to be addressed in greater numbers.

In astigmatism there is decreased visual acuity both for distance and near vision due to distortion or irregularity in the curvature of the cornea (eye transparent membrane that is directly in contact with the outside), which causes the edges of objects are observed blurred or poorly defined or perceived images look elongated or oval.

Children often complain that reading the lines “jump” and that some lines are blurred and more clear, which is added to classic symptoms such as headache, visual fatigue and sleep.

In very rare cases can occur at birth and have little variation throughout life. However, there are opinions that state that the problem may be exacerbated by making visual activities to less than 6 meters, which are promoted by physiological changes of the eyeball, and constant reading, using computer or watching television.

Advocates of this approach indicate that it is often advisable to relax the eyes, ie that for every 40 minutes from activities such as these need to rest for 5 to 10 minutes, ensuring that the vision away, ie display to far distances.
