An afterimage is a visual phenomenon that occurs when the eye continues to see an image even after the original source of the image has been removed. This effect is caused by the persistence of the visual system and can result in the perception of a ghostly image that fades away over time. Afterimages can be produced by staring at a bright light, a moving object, or a patterned image. They can also be induced by certain drugs or medical conditions. Afterimages are an important tool for understanding the workings of the visual system. They have been used to study the properties of the retina, the visual cortex, and the neural pathways that connect them. They have also been used to investigate the effects of drugs on the visual system and to diagnose certain medical conditions. In addition to their scientific applications, afterimages have also been used as an artistic technique. They have been used in photography, film, and animation to create a sense of motion or to convey a particular mood or emotion. They have also been used in painting and sculpture to create optical illusions and to explore the nature of perception. Overall, afterimages are a fascinating and complex phenomenon that have been studied and appreciated by scientists and artists alike. Whether used to understand the workings of the visual system or to create works of art, afterimages continue to captivate and intrigue those who study them.

Etymology, Morphology, Phenomenon, Retaining, Vision
The term “afterimage” is believed to have originated from optics. Specifically, when viewing an intense light source, the eye's photoreceptors can become saturated and can temporarily stop responding to light. This results in a phenomenon known as “persistent vision”, in which the stimulation of the photoreceptors is imprinted onto the visual cortex and continues after the light that created the image has been removed. It is through this concept of a perceived image that has been removed that the term afterimage was derived. In modern usage, however, the term is most often used to refer to a vivid mental image that remains in a person's mind after the memory has been forgotten or after the stimulus producing the image is removed. It is also used to refer to the mental representation of a previously experienced event or object.

Afterimage refers to the optical effect of a stabilized picture seen after the original stimulus has ceased. This phenomenon has been described interculturally through a variety of different terms. In French, it is referred to as an after-image, after-vision or after-sight, while in Spanish it is referred to as a tardia, a retaguardia, or an after-sight. Similarly, in Italian it is referred to as un'immagine dopo-occhio, in German as ein Nachbild, and in Russian as послеизображение. Korean terms include 뒤각고, 뒤감고 and 후각고. In Chinese and Japanese, it is referred to as 後視 and 後画, respectively, while in Portuguese it is referred to as uma imagem após-oculo.

Afterimage is an optical phenomenon in which an image continues to appear in the eye after the original source of the image has been removed. This image composition technique is often used in anime, comics and manga to create a sense of motion or to show the passing of time. Afterimage is a commonly used comic technique to create a sense of dynamic action, as if an action has just taken place and its ghost remains in the viewer’s vision until the image itself fades away.
