Question

Do explain what's astigmatism too

Answer 1

What Is Astigmatism?

It’s a big word, but it simply means your eye isn’t completely round. Almost all of us have it to some degree.
A normal eyeball is shaped like a perfectly round ball. Light comes into it and bends evenly, which gives you a clear view. But if your eye is shaped more like a football or the back of a spoon, light gets bent more in one direction than another. That means only part of an object is in focus. Objects at a distance may look blurry and wavy. It’s fairly easy for an eye doctor to fix with glasses, contacts, or surgery.

What Causes It?

It’s totally natural and most people are born with it. We don’t know the exact cause. You can also get it after an eye injury, eye disease, or surgery. There’s a myth that you can get it if you read in low light or sit too close to the TV, but that isn’t true
