Astigmatism of the eye usually involves the symptoms of blurred vision. It can also mean a person will have squinting and may soon feel tired or fatigued and suffer from headaches.
What does astigmatism mean A type of visual impairment. Due to the irregular curvature of the cornea or lens surface in the eyeball, the focal point formed by the parallel rays of light entering the eye is not in one place. Appears to see things blurry. Causes of astigmatism 1.Unequal curvature 2.Deviation of optical center 3.The refractive index varies Symptoms of astigmatism 1.Decreased vision 2.Asthenopia 3.Compensation for head position and squinting
Astigmatism is a medical condition. One in a million patients have it.
A spectacle lens is a lens worn in front of the eye, mainly used to correctmyopia, hyperopia,astigmatism.
The main symptom of astigmatism is blurring
The astigmatism chart was designed to evaluate whether a person has astigmatism, which is a condition which results in blurry or distorted vision. When a person looks at an astigmatism chart, all lines should appear to be the same darkness, clarity, and distance apart. A person with astigmatism will notice differences in the lines.

the defective curvature on the cornea or lens is called Astigmatism
Eye Doctors
This is an incomplete question but I am guessing that you have some astigmatism left at an axis of 100 degrees. Axis is a direction but not an amount, and if there is not much astigmatism, then this axis should not matter, but if the vision is blurry you may have some residual uncorrected astigmatism. Please discuss this with your eye doctor.
some common eye defects are:shortsightedness, longsightedness and astigmatism.

No. Anisocoria is a difference in pupil size and has nothing to do with astigmatism, which is a variation of the cornea or lens of the eye.
Astigmatism occurs when the eye is shaped like a rugby ball instead of a football, meaning it has one meridian that is steeper than the other. This is why you have 2 parts to your prescription. It is a very common problem and does not mean your eye is messed up. The vast majority of people have some degree of astigmatism and it can easily be corrected by glasses or contact lenses.
The eye. Astigmatism is when the cornea (the clear dome that covers the pupil) or the lens of your eye is not its usual perfectly round shape. Instead it's an oval shape, a bit like a rugby ball.
No, not really. Astigmatism simply means your eye is shaped more like a football than a baseball, and can be corrected with glasses. Eye pressure is the inflation pressure of the eyeball, like measuring the pressure of your tires. The eye pressure may be slighty off if measured on a patient VERY high astigmatism, but only by about one point, which is basically not significant. We usually don't pay attention to the astigmatism when measuring eye pressure.
