Purkinje images
![Diagram of light and four Purkinje images[1]](/uploads/202501/06/Diagram_of_four_Purkinje_images.svg0313.png)
Purkinje images are reflections of objects from the structure of the eye. They are also known as Purkinje reflexes and as Purkinje-Sanson images. At least four Purkinje images are usually visible. The first Purkinje image (P1) is the reflection from the outer surface of the cornea. The second Purkinje image (P2) is the reflection from the inner surface of the cornea. The third Purkinje image (P3) is the reflection from the outer (anterior) surface of the lens. The fourth Purkinje image (P4) is the reflection from the inner (posterior) surface of the lens. Unlike the others, P4 is an inverted image.
