Which term means double vision?

• A. Distal
• B. Diuresis
• C. Diplopia
• D. Dermatitis

Answer: (C)

Double vision is described medically as diplopia. The word breaks down into diplo- meaning double and -opia relating to vision, so it literally means seeing two images of one object. It happens when the eyes aren’t aligning properly or the muscles or nerves that control eye movement are impaired, leading to two overlapping views instead of one. The other terms don’t relate to vision at all: distal means far from the point of attachment, diuresis means increased urination, and dermatitis is inflammation of the skin.
