How astigmatism can affect your health?
What Is Astigmatism?
Astigmatism is a common condition in which the surface of the eye or cornea does not bend in the usual way, causing vision impairment.
Abnormal corneal curvature means that when light enters the eye, it focuses poorly on the retina, and the image becomes blurry.
It can also be caused by an irregularly shaped lens behind the cornea.
It can affect children and adults. It is usually congenital or present at birth but can develop after eye surgery or eye damage.
This is one of a group of eye diseases called refractive errors. They occur when the cornea or lens is not completely smooth and does not have a uniform bend.
Symptoms of Astigmatism
Symptoms of astigmatism may include:
- Blurry or impaired conception
- Problem seeing at sunset
Treatment of Astigmatism
If the astigmatism is mild, the doctor may not provide any treatment.
Otherwise, orthodontic lenses are a common approach and some people may benefit from laser surgery.
Astigmatism correction lens
Corrective lenses bend the incident light in a way that compensates for the error caused by inaccurate refraction. In this way, the image is projected correctly onto the retina.
They can take the form of eyeglasses or contact lenses. The usual recipe for near or far vision includes the power of a sphere to correct vision.
You will need a lens for astigmatism:
- Spherical force to correct myopia or hyperopia
- The power of a “cylinder” lens to correct astigmatism
- Axle designation to explain the position of cylinder correction
- Glasses may be suitable for children under the age of 12.
Anyone who wears contact lenses needs to know proper lens hygiene to reduce the risk of eye infections.
Orthokeratology, or corneal refractive therapy
This includes wearing specially adapted hard contact lenses, for example at night, to change the shape of the cornea. It doesn’t improve your eyesight forever, but it may look good all day long after you wear it.
Astigmatism is a common vision problem caused by an irregular cornea or an irregularly shaped part of your eye (its lens). You can read more about it on healthine.com
