Explanation
A person who can see nearby objects clearly but cannot see distant objects distinctly is suffering from myopia, also known as nearsightedness [2]. In a myopic eye, the image of a distant object is focused in front of the retina rather than directly on it [1]. This occurs because the eyeball is too long or the cornea/lens has excessive curvature [1]. Consequently, while near vision remains sharp, distant objects appear blurred. This is the opposite of hypermetropia (farsightedness), where distant objects are clear but near objects are blurry. Presbyopia is an age-related condition where the eye loses its power of accommodation, primarily making it difficult to see things up close [2]. Myopia is a common refractive error that can be corrected using a concave lens of suitable power to diverge light rays so they focus correctly on the retina [3].
