Hey Mate here is your answer....
.
Myopia is the inability to see things clearly unless they're relatively close to your eyes. Also called nearsightedness or shortsightedness, myopia is the most common refractive error among children and young adults.
Myopia occurs when the eye grows too long from front to back, causing light to come to a focus in front of the retina instead of directly on it. Other contributing factors include a cornea that is too curved for the length of the eyeball or a lens inside the eye that is too thick.
Distant objects and your driving vision will be blurry if you have myopia, but you still will be able to see nearby objects clearly. This is why the condition is also called "near-sightedness."
This causes light rays to focus at a point in front of the retina, rather than directly on its surface. Nearsightedness also can be caused by the cornea and/or lens being too curved for the length of the eyeball. In some cases, myopia is due to a combination of these factors.

Myopia
Near-sightedness, also known as short-sightedness and myopia, is an eye disorder where light focuses in front of, instead of on, the retina. This causes distant objects to be blurry while close objects appear normal
