Discover The Secrets Of Astigmatism Halos: Unveiling Clear Vision

Astigmatism is a common eye condition that occurs when the cornea, the clear outer layer of the eye, is not perfectly round. This causes light to be focused unevenly on the retina, the light-sensitive tissue at the back of the eye, resulting in blurred or distorted vision. Seeing halos around lights are one of the most common symptoms of astigmatism. It happens when light entering the eye is scattered and elongated due to the irregular shape of the cornea. The halos are often described as starbursts or streaks of light surrounding bright light sources, especially at night.

Astigmatism is a common condition, affecting up to 30% of the population. It can occur at any age but is most often diagnosed in people between the ages of 20 and 40. Astigmatism can be corrected with eyeglasses, contact lenses, or refractive surgery.

If you experience halos around lights, it is important to see an eye doctor to rule out any other underlying eye conditions.
