Untreated astigmatism is not dangerous, but high levels of astigmatism in young children can cause other vision problems such as “eye turns” or “lazy eye” (amblyopia).

Astigmatism normally happens alongside short-sightedness or long-sightedness. With mild astigmatism, you may not notice any problems with your vision.

Astigmatism can present at any age, but becomes more common as we get older. You can develop astigmatism over time, and the level of astigmatism can change as well.

How is astigmatism measured? Optometrists usually detect and measure regular astigmatism during refraction, when they place different lenses in front of the eye to determine a spectacle prescription.

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has ...

In children, if there is enough astigmatism present to cause blurred or distorted vision, it can impact their learning and development both in the classroom and during sporting activities.

The brain is an organ made up of neural tissue and has three main parts: the cerebrum, cerebellum, and brain stem. Each of these has a unique function.
