Causes of Astigmatism
Although the exact cause of astigmatism is unknown, heredity plays a significant role. It frequently exists at birth but can also appear later in adulthood. It might also happen following eye surgery or as a result of an eye injury. Together with nearsightedness or farsightedness, astigmatism frequently arises.
However, keratoconus, an uncommon disorder, can occasionally be the cause of astigmatism. This eye condition damages the cornea, causing the transparent tissue to thin and protrude. This causes sensitive eyes to bright lights and foggy or fuzzy vision. Keratoconus [1] also has an unknown etiology but is thought to be inherited.
You should also know that, although reading with low or dim lights can make it harder for eyes to focus, it doesn’t not affect vision or cause astigmatism. However, if you are already experiencing astigmatism, and you read in low light, you might notice increased blurriness.
Astigmatism can also be gotten from:
- eye disease
- eye injury
- after surgery
