We usually think of astigmatism as a threatening refractive error. While it is true that it is indeed a refractive error, astigmatism can be corrected and can easily be detected via an eye exam. In this article, we take a closer look at astigmatism and its different aspects.
Astigmatism as a Refractive Error
A refractive error occurs when light that goes into the eye is not refracted properly. Astigmatism is one of the most common types of refractive error in which light is not properly focused into the retina, the organ responsible for picking up visual details. As a result, images and objects appear blurry at any distance. Some cases of astigmatism are minor and do not have a significant effect in performing visual tasks.
Anyone who has consulted an eye doctor—either for a regular check-up or any other visual issues—will know that there is a test that checks for astigmatism. For those who are unaware, you will be asked by your eye specialist to look at multiple lines and determine whether they are all the same width and shade.
It’s important for your doctor to assess this, primarily because one symptom of astigmatism is blurred or distorted vision. Other factors indicative of this refractive error are constant headaches, night vision difficulties and eye discomfort due to excessive squinting.
Corrective lenses in the form of eyeglasses or contact lenses are the least invasive treatment for astigmatism. Another means of temporary treatment is Orthokeratology (Ortho-K) which uses rigid contact lenses to regulate corneal curvature. Lastly, you may choose to undergo refractive surgery as a permanent treatment option.
