Astigmatism is a fairly common condition that causes blurred or unclear vision, streaks through lights or double vision.

Is it normal to see flashes of light in the dark?

Why do lights look like starbursts?

Starbursts, or a series of concentric rays or fine filaments radiating from bright lights, may be caused by refractive defects in the eye. Starbursts around light are especially visible at night, and may be caused by eye conditions such as cataract or corneal swelling, or may be a complication of eye surgery.

What is seeing blurry lights called?

Astigmatism is a common vision problem caused by an error in the shape of the cornea. With astigmatism, the lens of the eye or the cornea, which is the front surface of the eye, has an irregular curve. This can change the way light passes, or refracts, to your retina. This causes blurry, fuzzy, or distorted vision.

What does it look like to see with astigmatism?

Do I need to wear glasses all the time for astigmatism?

Are glasses always required for astigmatism? No, not always. Some astigmatism is very mild, and sometimes astigmatism only occurs in one eye while the other eye has clear vision.

At what age is astigmatism diagnosed?

The AAPOS guidelines also recommend that children aged 1 to 4 years old should be tested by a pediatric eye doctor for astigmatism greater than 2 diopters, while older children must be checked for astigmatism greater than 1.5 diopters.
