WHAT IS ASTIGMATISM?

It is a refractive disorder in which 2 focal points are formed in eye.Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye.

THIS VIDEO EXPLAINS EVERYTHING ABOUT ASTIGMATISM.

​

CAUSES

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.

SIGNS AND SYMPTOMS

• HEADACHE

• CHANGE OF SHAPE OF EYE BALL,CORNEA,LENS

• EYE STRAIN

IF U FACE ANY OF THESE SYMPTOMS CONTACT YOUR OPTOMETRIST OR YOU CAN ALSO HAVE A VISIT AT THAREJA OPTICALS,SANGRUR​

How Is It Diagnosed?

You’ll need a thorough eye exam. Your doctor may also find another problem -- you could be nearsighted or farsighted. Because astigmatism symptoms come on slowly, you should go to an eye doctor if you notice changes in your vision.

How Is Astigmatism Treated?

Almost all cases can be corrected with glasses or contacts. But if you only have a slight astigmatism -- your doctor may refer to it as a degree -- and you don’t have another vision problem, you may not need them.

Irregular astigmatism is far less common and is linked to problems with your cornea, the front part of the eye. A common one is keratoconus, in which your normally round cornea becomes cone-shaped.

There are two treatments for the common levels of astigmatism:

Corrective lenses. That means glasses or contacts. If you have astigmatism, your doctor will probably prescribe a special type of soft contact lenses called toric. They can be made to bend light more in one direction than the other. If your case is more severe, you might go with a gas-permeable rigid contact lens. Your eye doctor will figure out which one is best for you.

Refractive surgery. This laser surgery changes the shape of your cornea. There’s more than one type, so your doctor will help you pick the one that’s right for you. You’ll need to have healthy eyes with no retina problems or corneal scars.
