Myopia, commonly referred to as nearsightedness, is a vision condition in which close objects appear clear, but distant objects are blurry. The correct answer is [B] Nearsightedness. This occurs when the eye’s shape causes light rays to focus at a point in front of the retina rather than directly on its surface. The eyeball may be too long, or the cornea may have too much curvature. This improper focusing prevents light from being correctly interpreted by the brain, resulting in a blurred image of distant objects. Myopia can be corrected using concave lenses, which diverge light rays before they enter the eye, moving the focal point back onto the retina. Corrective measures include eyeglasses, contact lenses, or refractive surgery. Unlike farsightedness (hyperopia), where the difficulty lies in seeing close objects, myopia specifically affects distance vision. Color blindness and night blindness are unrelated conditions affecting color perception and low-light vision, respectively.
