The diagram above is an illustration of a type of eye defect in humans. Study it and answer this question. The eye defect illustrated in the diagram is?

The eye defect illustrated in the diagram is Myopia, also known as nearsightedness. Myopia is a common eye condition that causes distant objects to appear blurry while nearby objects remain clear. In the diagram, the light rays coming from the distant object do not focus directly on the retina, which is the light-sensitive layer at the back of the eye. Instead, they focus in front of the retina, causing a blurred image. This happens because the eyeball is too long or the cornea is too curved, which causes light to focus incorrectly in the eye. People with myopia often have trouble seeing things like road signs or blackboards in a classroom, but can see things like books or computer screens clearly. Myopia can be corrected with eyeglasses, contact lenses, or refractive surgery, which can help to redirect the light rays onto the retina so that distant objects appear clear.
