Astigmatism is a common eye condition that causes blurred vision. It occurs when the front surface of the eye, or cornea, has an irregular shape. This causes light to be focused on multiple points instead of just one point on the back of the eye.
What Causes Astigmatism?
Astigmatism is usually caused by an irregularly shaped cornea. The cornea can become misshapen when it is exposed to pressure from the eye muscles, which can be caused by squinting or eye strain. It can also be caused by genetics, or even by an injury or surgery to the eye.
Can Anything Improve Astigmatism?
In many cases, astigmatism can be improved with the use of eyeglasses or contact lenses. These lenses help to correct the irregular shape of the cornea, which in turn helps to focus light correctly on the back of the eye.
In some cases, surgery may be necessary to correct astigmatism. This type of surgery, called refractive surgery, reshapes the cornea and helps to focus light correctly on the back of the eye.
If your astigmatism is caused by an eye muscle condition, such as a squint, then eye exercises and vision therapy may help to improve your vision.
Conclusion
Astigmatism is a common eye condition that can cause blurred vision. In many cases, it can be improved with the use of eyeglasses or contact lenses. In some cases, surgery may be necessary to correct astigmatism. Other treatments, such as vision therapy, may also be helpful in improving vision.
