Can you tell me how bad my astigmatism is?
Yes, uncorrected astigmatism can cause amblyopia, also known as lazy eye. If one eye has significant astigmatism, myopia or hyperopia, the brain can start to “tune out” the visual information from that eye and only use the information from the eye with better vision. This kind of amblyopia is called refractive amblyopia.
What does it mean to have really bad astigmatism?
When it gets much over 6 or 7 units, then the correction suffers and the vision will not be so good. This would be really bad astigmatism. The other really bad astigmatism is irregular astigmatism, which does not match a regular toric curve and for which lenses are not made for correction.
Can astigmatism get better on its own?
While it’s common for astigmatism to resolve on its own, parents should not necessarily rely on this. Keeping track of visual behaviors in your child can potentially save their eyesight, not to mention the (sometimes literal) headache of your child having to cope with limited vision.

- Eye discomfort such as headache or dizziness
- Eye squinting especially when looking at texts
- Blurry Vision or having blur on some areas only
- Poor Night Vision
- Eye Strain
Is having astigmatism a bad thing?
Astigmatism often occurs with nearsightedness and farsightedness, conditions also resulting from refractive errors. Astigmatism is not a disease nor does it mean that you have "bad eyes." It simply means that you have a variation or disturbance in the shape of your cornea.
Should I worry about astigmatism?
It is easily corrected, and although astigmatism can cause your vision to be blurry it rarely causes any permanent damage to the health of your eyes. If you experience blurred vision, headaches or eye strain, having a complete eye exam may lead to a diagnosis and treatment of this easily-dealt-with condition.
Will astigmatism make you blind?
Astigmatism is a problem of how the eye focuses light typically caused by a defect in the lens, resulting in distorted images. Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause blindness.
Can an astigmatism go away?
Neither glasses nor contact lenses permanently correct the curvature abnormality. Modern refractive surgery, which reshapes the surface of the eye with a laser, can also be used to reduce or eliminate the astigmatism. Wavefront guided LASIK or photorefractive keratectomy (PRK) can also reduce irregular astigmatism.
Does astigmatism get worse if you don't wear glasses?
As with almost every single eye condition, astigmatism only gets worse over time. The main reason for this is that, over time, the astigmatism changes angle and, without glasses or contact lenses at the very least, it only worsens.

There are three types of astigmatism: 1 Myopic astigmatism: This form of astigmatism occurs when the light is focused before it ever reaches the eye, much like myopia itself. 2 Hyperopic astigmatism happens when one or both of the eye’s meridians (invisible lines that run from right to left and top to bottom) are farsighted (people who can see clearly from up close but have difficulties seeing far away). This occurs with hyperopia. 3 Mixed astigmatism is the result of one principal meridian being near-sighted, with the other being farsighted.

A plus sign indicates you are farsighted, a minus sign indicates you are nearsighted. The higher the number, the stronger your prescription. 2 Cylinder measures what degree of astigmatism you have, or how flat or irregular the shape of your cornea is. The more your eye looks like an American football (instead of a basketball), the more astigmatism you have. 3 Axis is measured in degrees, and refers to where on the cornea the astigmatism is located. Axis numbers go from 0 to 180. If you think of the eye as a map hanging on a wall, the 90 degree axis or line, runs up and down (or north to south) on the eye. The 180 degree line runs across the eye, east to west.
