Symptoms and Causes of Astigmatism and How to Treat It

Astigmatism is an eye problem that causes blurriness to the eye vision. This eye problem is common to people and can easily be corrected by using prescriptive contact lenses, glasses, or surgery. A human’s cornea is normally shaped in a perfect sphere. When the light enters the cornea, it will equally be refracted in all directions and will form an image on the retina.

But to someone who has astigmatism, since their eye’s cornea shape is distorted, it will be difficult to form an image on the retina—thus resulting in cloudy and blurry vision. If you have any skin problems, the dermatologist is who you should go to. But for any eye conditions, an ophthalmologist is who you should approach when your eye issues have gotten worse. Now let’s talk about what are its causes, symptoms, and treatment of astigmatism.

Causes

In most cases, this eye condition is hereditary, which means it is passed on from one generation to another. This disorder is also common for people who always work in front of the computer, and people whose job requires constant eye precision such as embroidery. Another thing that causes astigmatism is incorrect posture, as it increases the stress on the cornea that can distort its curvature.

Symptoms

How do you know if you currently suffer from this eye disease? Experiencing blurriness and haziness vision is the most obvious symptoms of astigmatism. Blurry eye vision could also be a symptom of a lot of other health conditions. Even so, if you really are diagnosed with astigmatism, whatever object you see will still be blurry even though they are already close enough. Other indicators of astigmatism include fatigue, nausea, headaches, and eye pressure, as well as the disability to focus on a subject. You should consult your ophthalmologist if you’re experiencing these kinds of symptoms. They will be able to diagnose the origin of these signs.

Treatment

The remedy for this eye disease depends on how terrible it is. Mostly, in some cases, the level of their astigmatism is mild and can easily be with prescription lenses or glasses. Once you decide to go to the procedure with an ophthalmologist, they can suggest the ideal toric lenses fit for you after some tests.

In case of severe astigmatism, you can consider refractive surgery. This operation corrects the curvature and shape of the cornea, making it a perfect sphere. Once the surgery is done, the eyes will be able to form an image again as the light will evenly distribute to the retina.

With the improvement of technology, a series of measurements and operations have evolved. If you have astigmatism or suffer from some of these symptoms, you should go to your ophthalmologist and discuss the problem.
