Spasm of accommodation

Before you consider such a well-known concept as spasm of accommodation, you need to understand what exactly is this accommodation. Accommodation (from lat. Ассоmmodatio - device) is the eye's ability to see things equally clearly at different distances, and is due to a property of the lens to change the curvature, which in turn leads to a change of the refractive index of the entire optical system of our eyes. The main driving force of this process is the ciliary muscle, which is located in the ciliary body, when the tension relaxes Tsin connection, which the lens is attached to ciliary body. This process leads to a weakening of the tension of the capsule of the lens, which in turn becomes more convex due to its elastic properties. Accommodation of the eye is in the range between the nearest and farthest point of clear vision. When looking at distance the muscle is in the relaxed state, and when looked at near heokrasilsja and optical system of the eye maximizes the power of refraction, in order to clearly project the image on the retina. It is this increase in refractive power of the eye from lack of accommodation when looking at distance to the greatest stress it in the translation of sight in near vision is called the volume or power of accommodation. This figure varies depending on age, in connection with the loss of the lens by its elasticity.

Among the pathological changes of isolated accommodative spasm, paresis and paralysis. Spasm of accommodation is mainly due to her constant stress and usually occurs in young people due to excess eyestrain near. In connection with the development of modern computer technology and the advent of various gadgets are increasingly the main working area is the arm's length, and causes a constant voltage of accommodation, because our eyes are physiologically designed for the predominance of that is distance vision. But the spasm of accommodation, similar to a spasm in anyom the other muscle, the condition is temporary and should not be confused with myopia, in which anatomical changes occur in the optical system of the eye.

The main manifestations of spasm of accommodation are the so-called astenopiceski complaints: headache, rapid visual fatigue, pressing pain in the eyes and momentarily blurring into the distance with a sharp translation gaze. Usually these symptoms disappear after rest. To reduce the symptoms of spasm of accommodation required not less than once every 40 minutes when working in close proximity to to look somewhere far away in 2-5 minutes, and regularly do exercises for the eyes, as the better developed muscles of the eye, the greater the load they can withstand .

But the well-known theory that when developing myopia spasm of accommodation not confirmed by any scientific studies that would be conducted is not enough. The main cause of poor vision in the distance with myopia is the increased refractive power of the optical systemss eyes, with the result that the image falls on the retina but in front of it and the image becomes fuzzy. Although the muscular system of the eye changes as a result of attempts to compensate for poor vision is muscle tension, which in turn leads to fatigue and further deterioration of vision. The most effective way to reduce the progression of myopia is good vision with glasses and special exercises for the improvement of the entire muscular system of the eyes, which are standard exercises for Dashevskithat are known to our parents.
The basic principle of these exercises is to alternate tension and relaxation of all muscle groups of the eye using special prismatic lenses, which refract the image is not in the center of the retina, causing the eye muscles to move focus to the Central area of the retina. This set of exercises improves the tone and work the entire muscular apparatus of the eye, and as you know, the better the workout muscle the greater the load they can endure without compromising the view.

In conclusion I want to note that this situation, as the spasm of accommodation, can diagnose only eye doctor after a detailed examination. Do not self-medicate and consult a specialist, who will determine the best treatment plan for you.
