Astigmatism can cause focusing problems

When seeing becomes exhausting

November 2016

... then can functional visual disturbances be the cause. More and more people suffer from mental disorders such as exhaustion, tiredness, headaches, stomach and back problems. This is often caused by so-called functional disorders. There are no pathological changes, rather the organs affected are usually only disturbed in their function.

The complaints arise from Overstimulation of the autonomic nervous system. The cause can be a slight sensitivity which, under normal circumstances, is compensated by the body. A hectic lifestyle with a lack of time, high professional demands and leisure activities or mentally stressful situations can overload the vegetative nervous system. The body then reacts with complaints.

Functional visual disturbances

Often under these circumstances the eyes also strike and vision becomes strenuous. Modern lifestyle places high demands on vision. The eyes and nervous system are often overexcited: a long drive with poor visibility, a report that has yet to be finished on the computer or family organization that runs alongside. A day often ends with a headache and tired, burning eyes.

The autonomic nervous system also controls vision

When seeing, the conscious and unconscious nervous system work directly together. Each eye can be consciously turned in any direction with the six eye muscles. However, in order to be able to see clearly at all distances, the eye muscles are also coordinated by the autonomic nervous system. At the same time, the lens of the eye and the size of the pupil are automatically adapted to the visual conditions. The vegetative control also influences the eye muscles for opening and closing the eyes and the secretion of the lacrimal gland.

Functional visual disturbances

If the autonomic nerve control is overloaded, functional visual disturbances occur. This can manifest itself as blurred vision, unconscious pinching and twitching of the eyelids, dry eyes or excessive tears. The complaints usually arise in connection with uncorrected visual defects. In the case of vegetatively sensitive people or extremely strong nerves such as exam stress, functional visual disturbances can also occur without measurable visual defects.

In order to avoid functional visual disturbances as far as possible, even minimal visual defects should be corrected. Minor visual defects are often not noticed because the visual acuity is usually perceived as good. That is why you should always check your eyes if you experience complaints such as headaches and premature fatigue. Appropriate visual aids relieve the stress on vision and the nervous system.

Release inner tension through eye training

Inner tension leads to unconscious muscle tension. Conversely, muscle relaxation can also lead to inner relaxation. According to the principle of progressive muscle relaxation can Release inner tension through conscious muscle relaxation. Eye training and relaxation exercises in the head, neck and shoulder area not only relieve muscle tension, but also reduce inner restlessness and stress.

Therefore, take breaks from strained viewing

Interrupt long drives, computer work and long reading. Direct your gaze into the distance as often as possible, moving your eyes, not constantly staring in one direction. Get up and walk around, do relaxation exercises and eye training. The individual resilience is different, therefore personal limits are stuck. Realistic time planning with calculated breaks helps against the hustle and bustle. And remember: you usually don't have stress - you often create it yourself.

What makes seeing exhausting

  • uncorrected, also minor visual defects
  • high visual demands over long periods of time
  • Stressors

What makes seeing fatigue-free

  • Correct visual defects and wear visual aids
  • Take breaks from strained vision
  • Stress management

This is a prerequisite for fatigue-free vision with high visual demands
