Double vision that affects both eyes, typically from misalignment, is described by which term?

• A. Monocular
• B. Binocular
• C. Halos
• D. Total Blindness

Answer: (B)

Double vision that involves both eyes because the eyes are misaligned is called binocular diplopia. When the eyes don’t align properly, each eye sends a slightly different image to the brain, and the brain can’t fuse them into a single view, so you see two images with both eyes open. This type of diplopia typically improves or disappears when you close one eye, since only one image then reaches the brain. By contrast, monocular diplopia would still be present if the other eye were closed, because the problem lies within one eye itself. Halos refer to ring-like light patterns around bright objects and aren’t about two distinct images from both eyes. Total blindness means complete loss of vision in both eyes, which is unrelated to diplopia.
