Astigmatism is an eye condition that causes blurred vision due to a misalignment of the eye's lens or cornea. It is typically caused by a misshapen cornea, which causes light to be refracted in an irregular manner. Astigmatism can cause a variety of vision problems, including double vision.
Can You Have Double Vision With Astigmatism?
Yes, double vision is one of the most common symptoms of astigmatism. Double vision occurs when the eyes can’t focus on the same target at the same time. This can cause a person to see two images of the same object instead of one. In some cases, double vision can be mild and may not cause any disruption to daily activities. In other cases, it can be severe and can interfere with a person’s ability to perform everyday tasks.
What Causes Double Vision With Astigmatism?
Double vision with astigmatism is usually caused by a misalignment of the eye’s lens or cornea. When the eyes are misaligned, light is refracted in an irregular manner, causing double vision. In some cases, double vision can also be caused by a problem in the eye muscles, which control how the eyes move. This can cause a person’s eyes to move independently of each other, resulting in double vision.
How Is Double Vision With Astigmatism Diagnosed?
Double vision with astigmatism is typically diagnosed during an eye exam. During the exam, an ophthalmologist will use a series of tests to determine the cause of the double vision. These tests may include a refraction test, which measures how light is refracted in the eye, and an eye muscle test, which measures how the eye muscles work together.
How Is Double Vision With Astigmatism Treated?
Double vision with astigmatism can be treated with corrective lenses, such as glasses or contact lenses. These lenses are designed to help the eyes focus on the same target at the same time. In some cases, double vision with astigmatism can also be treated with surgery. This type of surgery can help correct the misalignment of the eye’s lens or cornea, which may help reduce or eliminate the double vision.
