After: Image

: These are the most common type. They appear in colors complementary to the original stimulus. For example, staring at a green object will produce a magenta afterimage because the green-sensitive cones in your retina become fatigued, leaving only the red and blue signals (which combine to form magenta) to be processed when you look at a neutral surface.

: Research from ScienceDirect indicates that while much of the process starts in the retina, the brain also plays a role in interpreting these lingering signals. Clinical Significance After image

An is a visual sensation that lingers in your field of vision after you have finished looking at a stimulus, such as a bright light or a high-contrast pattern. This phenomenon occurs because the photoreceptors (rods and cones) in your eyes temporarily lose sensitivity after being overstimulated by a constant image. Types of Afterimages : These are the most common type

: These retain the same colors as the original image. They typically occur after a very brief, intense exposure to light, such as a camera flash. Biological Mechanisms : Research from ScienceDirect indicates that while much
