Millions around the globe suffer from astigmatism, a common eye condition that distorts vision. Despite its prevalence, there is still a lot of misunderstanding and misinformation surrounding it. Astigmatism can affect people of all ages. This is why understanding the basics is crucial. Continue reading for more information about astigmatism.
Astigmatism primarily arises from an irregular curve in the eye lens or cornea. This alteration in shape often results in blurry vision because light doesn’t uniformly focus on the retina. The degree and specifics of astigmatism can be unique to each individual. This can range from a slight deviation that may not significantly affect vision to a more severe curve that causes notable vision distortion.
Astigmatism has a genetic component, and it’s possible to inherit it from both parents. It can also develop over time due to age or other factors. The condition is commonly present from birth, but many people don’t experience significant vision problems until later. Astigmatism can also result from an eye injury, eye surgery or certain eye diseases.
Some common symptoms of astigmatism include blurred or distorted vision at all distances, headaches, and excessive squinting. Eye strain and fatigue may also be signs of astigmatism, particularly after engaging in prolonged visual tasks. Some people might also experience difficulty driving at night. It’s important to note that these symptoms can also be associated with other eye conditions, so they don’t necessarily mean you have astigmatism. This is why regular eye examinations with an optometrist are crucial.
Diagnosing astigmatism involves a thorough eye examination by an eye doctor. The exam may include various tests such as vision testing using an eye chart, measuring the corneal curvature using keratometry and using corneal topography.
Treatment options for astigmatism depend on the severity of the condition. No treatment may be necessary for mild astigmatism. Optometrists usually prescribe glasses or contact lenses if the condition affects vision. Procedures like LASIK or PRK are popular surgical options that reshape the cornea to correct the irregular curve. These surgeries can provide long-lasting solutions, significantly improving vision clarity and reducing or even eliminating the need for glasses or contact lenses.
Several misconceptions about astigmatism can lead to confusion and unnecessary worry. One common myth is that astigmatism can lead to blindness. While it can impair vision, it is not a degenerative condition and will not cause blindness.
Another widely believed myth is that staring at screens for long periods or reading in low light can cause astigmatism. However, astigmatism is usually present from birth. Some people also believe that glasses or contact lenses cannot correct this eye condition. While severe astigmatism may require surgery, prescription eyewear and proper optical care can manage most cases.
