Astigmatism, a very common eye condition
#health Astigmatism is a type of refractive error of the eye. Refractive errors cause blurred vision. They are the most common reason why a person consults with an ophthalmologist.
Causes
People are able to see because the front of the eye (cornea) can bend (refract) light and focus it on the retina. This is the inner back of the eye.
If the rays of light are not clearly focused on the retina, the images you see may be blurred.
With astigmatism, the cornea is abnormally curved. This curve causes vision to be out of focus.
The exact cause of astigmatism is unknown. It is normally present from birth. Astigmatism often occurs along with nearsightedness or farsightedness. If astigmatism worsens, it may be a sign of keratoconus.
Astigmatism is very common. Sometimes, it happens after certain types of eye surgery, such as cataract surgery.

Due to old age, the muscles that stretch the eye lens weaken to look close. This makes most farsighted and we need reading glasses.

Although there is a risky slgot operation but that is not? I still think that if determined by the biological pattern

You start to see less from a distance, so after that, it is best to use lenses to improve your eyesight and stop the process of Antimagtism

It is true, I think that beyond being produced by electronic devices, it is something that is produced because it is inherited and progresses with age
