Which term describes double vision?

• A. Blurred vision
• B. Blindness in one eye
• C. Double vision
• D. Loss of color vision

Answer: (C)

Seeing two images of a single object is called diplopia. In everyday language we say double vision, which is exactly what the question describes. The other options refer to different vision problems: blurred vision means images are not sharp; blindness in one eye means complete loss of sight in that eye; loss of color vision refers to an inability to distinguish colors. Diplopia can be binocular (two eyes misaligned) or monocular (present when one eye is open and typically due to an issue in that eye).
