Summary of symptoms of astigmatism
- Astigmatism
- Visual disorders
- Burning eyes
- Headaches
- Long-sightedness (hyperopia)
- Nearsightedness (Myopia)
An experienced eye specialist can determine the astigmatism (astigmatism/ astigmatism) by means of a series of tests. These include a simple eye test, a refraction test, a corneal measurement or electronic imaging of the eye surface. Common symptoms of astigmatism (astigmatism/ astigmatism) are that both near and far objects appear blurred.
As a result, those affected often squeeze their eyes together in order to influence the refraction of light so that the image on the retina is as sharp as possible. The increased effort and also the increased muscular activity causes the muscles of the eye and the surrounding area to tense up, which often leads to severe headaches in those affected by astigmatism. The strength of the symptoms of astigmatism depends on the degree of curvature of the cornea and the extent to which refraction errors result.
Often people do not notice slight astigmatism because the brain can compensate to a certain extent for the difference in vision and insufficient focus. More pronounced astigmatism, in which there is clearly pronounced astigmatism/point-blurred vision, is noticeable due to blurred vision at close range and also at a distance. The eye will constantly try to focus on the distorted image, but adequate adjustment of the refractive power (accommodation) is no longer sufficiently possible from higher values.
This leads to overstraining with headaches and the eyes often start to burn. Even if astigmatism (astigmatism/ astigmatism) also occurs alone, it is often found in combination with other visual defects such as myopia, hyperopia or presbyopia. This further aggravates the symptoms of blurred vision caused by astigmatism (astigmatism).
Astigmatism/ astigmatism is still regular or normal when the values are between 0.5 and 1.0 diopters, because this degree of curvature represents the physiological deviation from the ideal circularity of the eye’s cornea and is therefore hardly or not at all noticed by those affected. It is not conclusive whether astigmatism can actually worsen, but it is often observed to do so. Thus, it develops insidiously and the patient does not notice any discomfort at the beginning, because the brain can then still sufficiently compensate for the blurred images. When the images become too blurred, the headache and burning sensation in question occurs because the ciliary muscles of the lens are overstrained. A general loss of visual acuity finally occurs when the brain is no longer able to compensate for the blurred images.
