The condition described is nearsightedness, which is a common refractive error of the eye. In nearsightedness, or myopia, distant objects appear blurry while close objects can be seen clearly. This occurs because the eye's shape causes light rays entering the eye to focus at a point in front of the retina instead of directly on it. The term specifically relates to the eye's inability to refractively focus images properly due to structural irregularities. Other options provided do not relate to the faulty refractive ability of the eye. Night blindness refers to difficulties seeing in low light conditions and is not directly related to refractive errors. Natural selection pertains to evolutionary biology, describing the process by which certain traits become more or less common in a population based on their reproductive advantages. Lastly, the option 'nerve' does not correspond to any known eyesight abnormality and is too vague in this context. Thus, nearsightedness accurately captures the aspect of a refractive error leading to poor distance vision.
