Signs and symptoms of astigmatism may include:
•Blurred or distorted vision
•Eyestrain or discomfort
•Headaches
•Difficulty with night vision
•Squinting
Children and adolescents
Children may not realize their vision is blurry, so they need to be screened for eye disease and have their vision tested by a pediatrician, an ophthalmologist, an optometrist or another trained screener at the following ages and intervals.
The eye has two structures with curved surfaces that bend (refract) light onto the retina, which makes the images:
•The cornea, the clear front surface of the eye along with the tear film
•The lens, a clear structure inside the eye that changes shape to help the eye focus on near objects
In a perfectly shaped eye, each of these elements has a round curvature, like the surface of a smooth ball. A cornea or lens with such curvature bends (refracts) all incoming light equally to make a sharply focused image directly on the retina at the back of the eye.

Feb 19, 2019 · Astigmatism is a condition caused by subtle flaws in the way your eye bends light ( a process called refraction) that passes to the retina, the light-sensitive area at the back of the eyeball. The optic nerve transmits nerve impulses from the retina to the brain, which translates them into eyesight.
