The problem of astigmatism can be tough to realize. It is a refractive mistake that can be existing from birth or develop during childhood years or after eye injuries or surgery.

The cornea and lens job to refocus light getting in the eyes right into a solitary centerpiece on the retina. With astigmatism, light goes into the eye in two different areas and also produces fuzzy or distorted photos.

Reasons

Astigmatism is a refractive mistake, which means that light going into the eye does not focus exactly on the back of the eye (the retina). The outcome is fuzzy vision.

Usually, the cornea as well as lens refract light precisely to make sure that light signals are focused on the retina to produce clear, crisp pictures in the brain.
