How Astigmatism Alters Your Sight
Understanding Astigmatism and Night Vision
Astigmatism is a common eye condition that causes blurred vision due to the irregular curvature of the cornea or lens. This can lead to difficulties seeing objects clearly, especially at night or in low-light conditions.
When people with astigmatism look at lights at night, they may see starbursts, halos, or streaks around the light source. This is because the irregular shape of the cornea or lens causes the light to scatter and distort as it enters the eye. The amount of distortion and the type of visual disturbances experienced can vary depending on the severity of the astigmatism.
In addition to blurry vision and distorted lights, people with astigmatism may also experience other symptoms such as eye strain, headaches, and difficulty driving at night. It's important for people with astigmatism to get regular eye exams to ensure their prescription is up-to-date and to monitor the health of their eyes.
There are a number of ways to correct astigmatism, including eyeglasses, contact lenses, and refractive surgery. Eyeglasses and contact lenses can help to improve vision and reduce the symptoms of astigmatism. Refractive surgery can permanently correct astigmatism by reshaping the cornea.
If you think you may have astigmatism, it's important to see an eye doctor for a comprehensive eye exam. Early diagnosis and treatment can help to prevent vision problems and improve your overall quality of life.
