Asthenopia (Eye fatigue syndrome)
Asthenopia or Eye fatigue syndrome is a fairly fast oncoming eye fatigue during visual work, especially if the observed object is at a very small distance from the eye. This disease is divided into: astenopia of the muscular and astenopy accommodative
In most cases, asthenopia occurs in people who, due to their work, have to read a lot of literature or work long hours at the computer. However, not only this can cause the development of this disease. Occurrence of asthenopia can contribute to various visual abnormalities: astigmatism, myopia and hyperopia. Sometimes the development of the disease lead to age-related changes, so that the eye develops defocusing when observing nearby objects (the onset of manifestations in most cases after forty years).
Muscular asthenopia most often develops with uncorrected myopia and is much less likely due to the inherent weakening of the internal direct eye muscles. With this type of disease, there may be a violation of binocular vision and the development of strabismus.
The accommodative asthenopia develops as a consequence of excessive fatigue of the ciliary muscle of the eye, which regulates the curvature of the lens, as well as with astigmatism or farsightedness
- There is a feeling of heaviness and fatigue in the eyes
- After a long visual work at a short distance, there is headache and eye pain
- The size and shape of the observed objects are distorted
- Inflammation of the eyes and lacrimation
- Vagueness and bifurcation of the image
- Shroud before the eyes
Diagnosis and Treatment
The diagnosis is made by an ophthalmologist, based on the results of a special ophthalmological examination and characteristic patient complaints. , слабость цилиарной мышцы, близорукость или дальнозоркость. Often simultaneously identified: astigmatism , weakness of the ciliary muscle, myopia or hyperopia.
For quality treatment, as well as asthenopia prevention, it is necessary to perform general strengthening therapy, observe the necessary standards of visual hygiene, conduct timely timely correction of myopia and farsightedness, as well as a correctly balanced time for work and rest of the eyes (when working at a computer, it is necessary to interrupt for ten minutes and translate a look from the monitor to the window, focusing alternately on distant, then on near objects outside the window).
