Diplopia is the medical term for which visual phenomenon?

• A. Double vision
• B. Blurred vision
• C. Loss of vision
• D. Floaters

Answer: (A)

Diplopia means double vision—seeing two images of a single object. This happens when the eyes don’t align properly or the brain can’t fuse the two retinal images into one, often due to muscle or nerve issues or refractive/ocular surface problems. It’s different from blurred vision (one hazy image), loss of vision (seeing nothing), or floaters (tiny moving spots).
