Astigmatism Symptoms

Astigmatism symptoms are symptoms of astigmatism whereas an optical defect blurs the vision due to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina. This may be due to an irregular or toric curvature of the cornea or lens.

The two types of astigmatism are regular and irregular. Irregular astigmatism is often caused by a corneal scar or scattering in the crystalline lens, and cannot be corrected by standard spectacle lenses, but can be corrected by contact lenses.


To see further examples of what is astigmatism feel free to look inside this "Astigmatism Treatments - Natural Eyesight Improvement for Clear Vision" kindle edition book that not only sheds some light on astigmatism, but has some specific exercises to remedy the condition. Also, for a broader approach to diet and vision improvement, see "How To Improve Your Eyesight" listed below.

Regular astigmatism arising from either the cornea or crystalline lens can be corrected by a toric lens. (Note:- before running off to your eye care specialist for lasik astigmatism corrective surgery, we encourage you to try the natural alternatives as soon as the symptoms of astigmatism.are known, because there are numerous reports of successful natural cures via eye exercise and proper diet.
A toric surface resembles a section of the surface of an American football or a doughnut where there are two regular radii, one smaller than the other one. This optical shape gives rise to regular astigmatism in the eye.^[1]

The refractive error of the astigmatic eye stems from a difference in degree of curvature refraction of the two different meridians (i.e., the eye has different focal points in different planes.) For example, the image may be clearly focused on the retina in the horizontal (sagittal) plane, but not in the vertical (tangential) plane.

Astigmatism causes difficulties in seeing fine detail, and in some cases vertical lines (e.g., walls) may appear to the patient to be tilted. The astigmatic optics of the human eye can often be corrected by spectacles, hard contact lenses or contact lenses that have a compensating optic, cylindrical lens (i.e. a lens that has different radii of curvature in different planes), or refractive surgery.
