Full Medical Biography<\/a>\n\n\n\nWhat Is Astigmatism?<\/h3>\n\n\n\n Astigmatism belongs to the so-called refractive errors, which cause a disruption in the way light rays are focused within the eye. Astigmatism can be classified as regular or irregular.<\/p>\n\n\n\n
In simple terms, someone may suspect they have astigmatism when they see distorted or blurred images at both near and far distances. Even if your vision seems clear, you may experience headaches and eye strain.<\/p>\n\n\n\n
Forms of Astigmatism:<\/strong><\/p>\n\n\n\n\nCorneal astigmatism<\/li>\n\n\n\n Lens astigmatism<\/li>\n\n\n\n Retinal astigmatism<\/li>\n<\/ul>\n\n\n\nAstigmatism is not a disease, but a refractive anomaly that usually remains stable throughout life. Any significant change in astigmatism may indicate a more serious condition that should be carefully examined by a doctor.<\/p>\n\n\n\n
Causes<\/h3>\n\n\n\n Astigmatism is a defect that can be congenital or arise from an injury or corneal disease. In this condition, the cornea is not perfectly spherical and does not have the same curvature in all meridians. In other words, the cornea may be more curved along one axis, resembling a rugby ball, causing blurred vision because the eye cannot focus light rays onto a single point.<\/p>\n\n\n\n
Symptoms<\/h3>\n\n\n\n Blurred vision is clearly the main symptom of astigmatism, along with distorted images at all distances. If the individual does not wear glasses or contact lenses, other symptoms may include eye strain, headaches, and fatigue after prolonged reading or many hours spent at a computer.<\/p>\n\n\n\n
Diagnosis<\/h3>\n\n\n\n Astigmatism can be diagnosed through a simple visual acuity test or corneal topography.<\/p>\n\n\n\n
Treatment \u2013 Laser Therapies<\/h3>\n\n\n\n To correct astigmatism, eyeglasses or contact lenses are usually recommended. If the doctor deems it necessary, laser refractive surgery can be performed to permanently correct astigmatism.<\/p>\n\n\n\n
In older patients, surgical implantation of a toric intraocular lens with simultaneous replacement of the natural lens may be performed. This procedure is often combined with cataract removal, and the cost varies depending on the individual case.<\/p>\n\n\n\n

How common is astigmatism?<\/span>\n\n\n\n<\/rect><\/polyline><\/svg><\/span><\/rect><\/polyline><\/svg><\/span><\/span>\n<\/div>\n\n\n\n\n
\n
Astigmatism is a very common refractive anomaly, and it is estimated that most people are born with a mild degree that usually remains stable throughout life. The difference in vision is minimal, and in most cases, there is no reason for concern.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

\n
Is astigmatism responsible for headaches?<\/span>\n\n\n\n<\/rect><\/polyline><\/svg><\/span><\/rect><\/polyline><\/svg><\/span><\/span>\n<\/div>\n\n\n\n\n
\n
It can be, because the eye is forced to struggle to focus an image, often without success. This effort can trigger a headache, which usually improves when wearing the appropriate corrective glasses.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

How does someone with astigmatism see?<\/span>\n\n\n\n<\/rect><\/polyline><\/svg><\/span><\/rect><\/polyline><\/svg><\/span><\/span>\n<\/div>\n\n\n\n\n
\n
A person with astigmatism usually has reduced visual sharpness. For example, when looking at a wall clock, they may have difficulty distinguishing the hands clearly along certain axes, and tilting the head slightly can shift which axes appear sharper. With the correct pair of glasses, vision can become clear and uniform again.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Can astigmatism be corrected with contact lenses?<\/span>\n\n\n\n<\/rect><\/polyline><\/svg><\/span><\/rect><\/polyline><\/svg><\/span><\/span>\n<\/div>\n\n\n\n\n
\n
Both high and low astigmatism can be corrected with contact lenses, providing stable and comfortable vision.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Can someone have special lenses for astigmatism in sunglasses?<\/span>\n\n\n\n<\/rect><\/polyline><\/svg><\/span><\/rect><\/polyline><\/svg><\/span><\/span>\n<\/div>\n\n\n\n\n
\n
Yes. This is a very convenient solution, as it allows you to wear sunglasses without it being obvious that they correct astigmatism, while still providing clear vision. The cost of converting regular lenses to astigmatic lenses is not high, and your ophthalmologist can guide you through the process.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
