What is Astigmatism, and How Is It Corrected?
Have you heard of astigmatism but aren’t sure what it is or how it is corrected? Astigmatism is a refractive error in an individual’s eye that affects how they see objects. It occurs when the cornea of the eye, which acts like a lens, is not shaped correctly. This causes blurry vision and possible headaches. Let’s look at what astigmatism is and how it can be corrected.
What Causes Astigmatism?
Astigmatism can be caused by genetics, trauma to the eye, or even an incorrect eyeglass prescription. When light enters the eye, it should be focused on one point at the back of your eye. However, if your cornea isn’t shaped correctly, then this light will end up being dispersed across multiple points instead of just one point. This means that objects appear blurry and distorted when seen through your eyes.
How Is It Diagnosed?
Astigmatism can be diagnosed during a routine eye exam with an optometrist or ophthalmologist. During this examination, they will measure your corneal curvature to determine if there are any irregularities present. They may also ask you to read from an eye chart to check for visual acuity and depth perception issues associated with astigmatism. If any issues are found, additional testing may be conducted to confirm a diagnosis of astigmatism.
How Is It Corrected?
In most cases, astigmatism can be corrected with eyeglasses or contact lenses specifically designed for individuals with this condition. These lenses have special curves that help refocus light onto a single point at the back of your eyes so that objects become clearer and more accurate again. Additionally, corrective surgery such as LASIK can be used to reshape the cornea so that light focuses properly again without needing to use glasses or contacts all the time.
Astigmatism is a common refractive error in an individual’s eye that affects their vision clarity and accuracy. It occurs when there are irregularities in the shape of their cornea which causes light entering their eyes to disperse across multiple points instead of just one point at the back of their eyes. The good news is that astigmatism can usually be diagnosed during routine eye exams by optometrists or ophthalmologists and corrected through either eyeglasses or contact lenses designed specifically for this condition or corrective surgeries such as LASIK surgery! For those who suffer from astigmatism, these treatments provide people with an opportunity to experience improved vision clarity and accuracy!
