Myth 1: Astigmatism is caused by squinting
Unlike most eye problems, astigmatism is not caused by squinting. Rather, it's the result of irregularities in the eye's cornea as well as lens that result in blurry vision.
Typically, the cornea and also lens at the front of your eye have a rounded shape that allows light to focus sharply on the retina at the back of your eyeball.

It influences adults and children alike.
Myth 2: Astigmatism is a hereditary problem
Astigmatism is a refractive error triggered when your cornea or lens have an uneven curve. This mismatch triggers light that enters your eye to be curved unevenly, which can trigger blurry vision in any way ranges. Lots of people that have astigmatism are born with it, however some may get it from eye injuries, conditions or surgery.

There are 2 types of astigmatism: routine and uneven. A normal astigmatism suggests that your cornea - the clear front layer of the eye - isn't completely round like a basketball, however it is a lot more extended, shaped more like a football. This implies that the light entering your eye strikes the retina at more than one point, which leads to fuzzy or distorted vision. The other sort of astigmatism is irregular astigmatism, which suggests that your cornea and/or lens are bent in more than one direction or steeper in the bottom than the top.
Myth 3: Astigmatism is irreversible
A lot of astigmatism is hereditary. However it can also be caused by eye injuries, surgical treatment, aging, or scarring. It could even establish from the shape of your cornea or lens.

Other choices include orthokeratology, which makes use of stiff contact lenses to reshape the cornea, or laser surgical procedure.
Myth 4: Astigmatism hurts
The eye is designed to filter light into the retina and also focus it onto the back of the eye (the cornea or lens). When these structures are misshapen, however, vision can be blurry. This refractive error can be fixed with prescription eyeglasses and also contact lenses or by having astigmatic keratotomy surgery, which involves making little cuts on the steepest curves of the cornea.
One of the most usual symptom of astigmatism is obscured vision, which can make it illegible or see objects in the distance, also when you are resting close to them.
