What to do for a astimatism?
I am assuming you mean astigmatism. This is a very common eye condition caused by an irregularly shaped cornea (called corneal astigmatism). But sometimes lenticular astigmatism results from an irregularly shaped lens, which is located behind the cornea.Either kind of astigmatism can usually be corrected with eyeglasses, contact lenses, or refractive surgery.It is separate from having either myopia (nearsightedness) or hyperopia (Farsightedness), meaning a person who has astigmatism may be nearsighted, farsighted or neither.The best thing is to go to an eye doctor and get examined. Once you have your diagnosis you can discuss your options with the doctor.
What is corneal astigmatism?
Astigmatism is blurred vision caused by an irregularly shaped cornea. Astigmatism is when the cornea of the eye is shaped like a rugby ball rather than being spherical. It causes the eye to have two focal points rather than one and can lead to strain and headaches if uncorrected. Astigmatism is the 'Cylinder' value in a prescription. Around 70% of people who wear spectacles have astigmatism. It can also be corrected with toric contact lenses and laser eye surgery. People with severe astigmatism may experience double vision if it not corrected. Astigmatism can indeed worsen with time, as the eye grows and changes. There is nothing you can do to prevent this change and it will only require a change to the prescription in your glasses in order to correct your vision. It is also possible for the astigmatism to go away. It's when the eyeball is not perfectly round.
