Migraine and vision

A plenty of researches of the visual analyzer have shown presence of its features at patients with a migraine, distinct from healthy. Into structure of the visual analyzer enters not only an eye with its muscular apparatus, but also spending ways of an optic nerve, and also a site of a cortex of a brain to occipital area. At patients with a migraine the level of excitability of a brain is raised, it leads to hypererethism and a susceptibility of the visual analyzer. The additional load on it leads to rising of instability of system, rising of risk of occurrence of an attack.

One of the most widespread reasons of rising of a strain of the visual analyzer is absence of correction of vision or wrong correction. At a myopia or a hyperopia the constant control over change of vision is insufficient. The complex of the special gymnastics, allowing to suspend the further advance of disturbance of vision is necessary. Any good oculist or the ophthalmologist a sign with these exercises also applies them in the practice.

Very important question is wearing glasses. In no event the patient with a migraine cannot neglect references of the oculist on application of glasses for reading and for a distance. To apply a distance spectacles at work behind a computer or at reading it is not authorized. Except for correctly picked up diopters it is necessary to check up correctness of selection of distances centre to centre an eye.

Some words about application of sunglasses. Their frequent application reduces an additional load on the muscular apparatus of an eye and salutarily acts on current of a migraine, reducing probability of an extraordinary attack.

And here work behind a computer or behind a desktop with incorrectly picked up illumination considerably enlarge this probability. As the image on the screen of a computer represents high-pitched submission of the image it leads to body height of a strain in the visual analyzer. Therefore recommended restrictions for work on a computer the following: five-minute breaks in current of each business hour behind a computer are necessary, and also operation time should not make more than 6 hours per day in view of an one hour's interval in the middle of this working day.

Long tiring driving of the car on greater distances also can lead to occurrence of an attack. It is bound as to the raised load on vision, and the raised intense attention, that in aggregate leads to occurrence of hypererethism of a cortex and at action of such provoking factor as exhaust gases from which it is not possible to be to the full protected neither to the driver, nor the passenger can lead to occurrence of an attack. Presence near at hand Zomig will allow to take out effectively an attack and to prevent occurrence repeated, however keeping of the set forth above rules of the attitude to the vision should obligatory for the patients, suffering a migraine.
