About Astigmatism
It occurs because of imperfections in the curvature of the eyes. It is a disease, and the reason behind it is that it can last forever if it is not appropriately diagnosed. Astigmatism occurs when the curves on the eye’s front surface (cornea) or the lens inside the eye are misaligned. The cover is shaped like an egg rather than having a single curve like a round ball. Vision becomes blurry as a result at all distances. Astigmatism is frequently present at birth and can coexist with other refractive errors like nearsightedness or farsightedness. Corrective lenses or surgery are available as treatments.
Astigmatism- refractive error occurs when the cornea or lens is more sharply curved in one direction than the other. If your cornea has mismatched curves, you have corneal astigmatism. If your lens has mismatched angles, you have lenticular astigmatism. Both types of astigmatism are responsible for blurred vision. Vision blurriness may be more prevalent in one direction: horizontally, vertically, or diagonally. Astigmatism is a particular kind of refractive error of the eyes. Reading in low light, sitting too close to the television, or squinting do not cause or worsen astigmatism.
