What is Astigmatism?
Astigmatism is a common refractive error which causes blurry or distorted vision because it impairs the eye's ability to focus light evenly onto the retina. This condition occurs when the cornea or the lens of the eye has an irregular shape, rather than the normal spherical shape. As a result, light rays entering the eye are not properly focused, leading to vision problems.
Whare are the Common Symptoms of Astigmatism?
Astigmatism can occur on its own or in combination with other refractive errors such as nearsightedness (myopia) or farsightedness (hyperopia). Common symptoms of astigmatism include blurry or distorted vision at all distances, headaches, eyestrains, and difficulty seeing at night.
How Common is Astigmatism?
Astigmatism is quite common, with many people experiencing some degree of astigmatism. It can be present from birth or develop later in life. While the exact cause of astigmatism is not always clear, genetics is believed to play a significant role in its development. Factors such as eye injuries, eye surgery, or certain eye conditions may also contribute to the development of astigmatism.
Treatment Options for Astigmatism
Fortunately, astigmatism can be easily diagnosed during a comprehensive eye exam conducted by an optometrist or ophthalmologist. Treatment options for astigmatism typically include prescription eyeglasses or contact lenses that can help correct the refractive error and improve vision. Occasionally, refractive surgery such as LASIK may be recommended to reshape the cornea and correct astigmatism.
It is important to have regular eye exams to detect and correct astigmatism early, to prevent further vision problems and ensure good eye health.
