Double vision, also known as “seeing double” or the medical term diplopia, is the perception of two images of a single object. This occurs when two non-matching images are sent to the part of the brain that processes visual input. Over time, the brain eventually begins to compensate for this misinformation by suppressing one signal so that only a single image is perceived.
There are many different causes for double vision, ranging from life-threatening to benign. Consequently, when diagnosing double vision and creating a treatment plan, it is critical for a medical professional to determine the specific cause in order to develop an appropriate treatment plan.
