A patient seeing no light at all is described by which term?

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

Answer: (C)

When vision is described as having no light perception, the term used is total blindness. This means there is a complete lack of ability to detect any light in the visual field, in contrast to partial vision loss. Monocular and binocular refer to whether vision is limited to one eye or both eyes, not the presence or absence of light perception. Halos describe a visual phenomenon around lights, not a state of complete light detection loss. So the term that fits “seeing no light at all” is total blindness.
