What is diplopia commonly known as?

Diplopia is commonly known as double vision. This condition occurs when a person sees two images of one object, which can be perceived horizontally, vertically, or diagonally. It is often a result of misalignment of the eyes due to problems with eye muscles, the nerves controlling those muscles, or issues in the brain. Understanding that diplopia specifically refers to experiencing two images is crucial in distinguishing it from other visual impairments. Other conditions listed, such as blurred vision, night blindness, and color blindness, refer to different visual symptoms and do not relate to the experience of seeing double images.
