The internet can be useful in so many ways, and this time it surprised us with some interesting yet weird facts that the majority didn’t have a clue about. How well do you know your eye? Most people know that they have a perfect vision, a 20/20 but others, blind as a bat. But how well, do you know other eye conditions that may come in between?

An ordinary photo posted on the twitter account @Unusualfacts6 went viral for showing the difference between normal vision and what people with astigmatism see.

This is a condition that results when the cornea is slightly curved and makes people with this condition experience light as sharp illuminations.A normal eye has both the cornea and lens curved in a rounded shape which both refracts any incoming light to produce a sharply focused image on the retina.

In astigmatism, the cornea and lens have mismatched curves which cause a refractive error that prevent the light rays from bending properly, the result is a blurry image.
The two types of astigmatism are corneal astigmatism (mismatched curves in the cornea) and lenticular astigmatism (mismatched curves on the lens) both of which can cause a blurry vision that can occur horizontally, vertically or diagonally.
People with this condition can also experience symptoms like eye strain or discomfort, headaches, and difficulty seeing at night. The most common way to treat this condition is contact lenses, eyeglasses, and surgery.
Reports from the World Health Organization say that refractive errors are both the most common ocular problems but are also the first cause of visual impairments and the second cause of visual loss worldwide.
