Astigmatism
Astigmatism is a common eye condition in which the cornea or lens of the eye is irregularly shaped, causing distorted or blurred vision. This can occur when the eye is not perfectly spherical, causing light to be refracted unevenly and resulting in vision that is not as clear as it should be. Astigmatism can occur in combination with nearsightedness or farsightedness and can be diagnosed by an eye doctor through a comprehensive eye exam. The most common treatment for astigmatism is corrective lenses, such as glasses or contact lenses, which can help to refocus the light entering the eye and improve vision. In some cases, refractive surgery may also be an option for treating astigmatism. It’s important to have regular eye exams to detect astigmatism and other vision problems early on, so that appropriate treatment can be administered.
Signs of Astigmatism
Percentages of astigmatism can go undetected, however, you may be experiencing eye tiredness, eyestrain, and headaches.
Astigmatism is a condition that typically can develop early in youth. According to a study from The Ohio State University School of Optometry, 28% of school-age kids experience astigmatism. Parents must know that their kids might not observe that their vision is blurred, not understanding that this is not regular.
Nonetheless, astigmatism must be dealt with since vision problems can lead to discovering issues in extracurricular activities. Ensure to have your kid’s eyes analyzed at an eye doctor’s workplace at least as soon as a year.
Causes of Astigmatism
Astigmatism is generally triggered by a cornea with an irregular shape. The cornea is the front, clear layer of the eye. With astigmatism, the cornea is not round and spherical and is instead irregular having two curves rather than one curve. Astigmatism in some cases could likewise be triggered by the lens situated inside the eye that is irregular in shape.
Eyes with astigmatism misshape the light that enters into the eyes because the cornea is irregularly formed. This causes the light rays getting in the eye to produce two images in the back of the eye (since of the 2 curves), instead of one image. This is what causes the distortion in sight.
Treatments for Astigmatism
For the majority of people, their astigmatism is completely fixed by utilizing prescription glasses or contact lenses. If you pick contact lenses to correct your vision, soft contact lenses are the most typical alternative. If for whatever reason soft contact lenses are not an option, rigid gas permeable (RGP or GP) are also a great option. Rigid gas-permeable lenses normally give the clearest vision but the adaptation process will be significantly longer. Another option is hybrid contact lenses. These contacts have actually a center made from a rigid gas permeable (RGP) lens and an external ring made from a soft contact lens product. This kind of lens offers both exceptional clearness and convenience. LASIK could be another alternative to fix astigmatism. LASIK usually only corrects low levels of astigmatism and some patients with greater levels of astigmatism might not be candidates.
