Astigmatism is a typical visual issue caused by a corneal defect. In astigmatism, the eye lens or the cornea, which is the anterior surface of the eye, has an elliptical curvature. This can change the manner in which light gets on your retina or refracts. This leads to blurred or distorted vision. The cornea of the eye is usually smooth and uniformly curved in all directions. This ensures that the light that falls into the cornea is focused in all directions.
Types of Astigmatism
When the cornea is curved excessively or when the eye is very long than expected it leads to myopia. Individuals experiencing this condition, the light is focused before the retina rather than focusing on the retina. This leads to a blurred vision of long-distance items.
This condition transpires when the curvature of the cornea is less or when one’s eye is shorter than normal. This condition is the inverse of myopia, where the light is focused behind the back of the retina, creating a blurred vision of close items.
3. Mixed Astigmatism
Here, the light rays reach two focal points, one of which is in front of the retina and the other behind the retina.
Causes of Astigmatism
In most cases, this disorder is inherited, i.e. it is transmitted from one generation to another. In addition, it is as well common in individuals who spend most of their time in front of the computer or participate in some activities such as embroidery which subjects the eye to constant focus.
Circulatory issues caused by stress and tension are as well as causes of astigmatism. In this case, an accumulation of stress and tension in the neck muscles can lead to a restriction of blood flow to the head and eyes.
Diabetes is another leading factor because certain individuals with this condition might develop a type of astigmatism referred to as lenticular astigmatism. For this situation the patient’s cornea is normal and the only anomaly is in the form of the lens. High blood sugar levels can adjust the shape of the lens and affect vision. This condition is transient as the shape of the lens come back to normal after effective treatment.
Symptoms of astigmatism
The most common symptoms of astigmatism are;
1. Blurred or distorted images at short or long range
4. Narrowed eyes (such as an attempt to see an object more clearly),
5. Eye fatigue (when the eye is forced to focus for a long time).
You should consult your ophthalmologist to perform a complete eye exam that includes astigmatism testing. Depending on the seriousness of astigmatism, your specialist may give you a lens or contact lenses to solve the condition.
This is another method to treat astigmatism, and it’s a pain-free process. It includes wearing a progression of uniquely created rigid gas permeable (RGP) contact lenses are being used to constantly reshape the corneal curvature. The procedure can be compared with the use of braces to straighten curved teeth.
Laser medical procedure
It can likewise be used to treat a few kinds of astigmatism. The medical procedure changes the condition of the cornea by removing a little amount of tissue from the eye. This is done with an exceptionally centered laser beam around the eye surface.
Individuals with astigmatism are lucky to have a broad range of options available to treat the disease. With the help of Ewing Optical ophthalmologist, you can choose the treatment that best suits your visual and lifestyle needs.
