Normally, the shape of the cornea is to resemble the surface of the sphere, which is perfectly round. Astigmatism (cylinder) occurs when the shape of your cornea is irregular. As a result, astigmatism can make the patient unable to see the shadow of the incoming object (generally becoming shaded, italic or blurred).

Astigmatism is categorized into 4, ie mild (less than 1.00 diopters), moderate (1.00 to 2.00 diopters), high (2.00 to 4.00 diopters), and extreme (more than 4.00 diopters). So, your condition is actually still quite moderate, not high.

However, because your complaints occur along with myopia (nearsightedness), then the complaints may feel worse. This can make you experience limitations in the activity due to constrained vision problems.
Unfortunately, until now there has been no other way to cure astigmatism and myopia except through surgery.

Therefore, you should see your ophthalmologist directly for further treatment. If you intend to undergo surgery, your doctor will evaluate whether you are the right candidate or not.

In addition to surgery, astigmatism and myopia can also be corrected (not treated) with the use of special glasses. Selection of these glasses was ideally done directly by discussing with an ophthalmologist. With the right glasses, you can perform activities with normal without constrained vision, and eye refraction disorders can be prevented so as not to deteriorate.
Currently, in addition to using glasses, so that your refractive eye disorder does not get worse, you should avoid reading too closely, especially in poor lighting conditions.
