What causes prism in eyes?
This causes the images from each eye to be off a little, making you see two images. With this type of double vision, the images often are completely distinct with space between them.

Fresnel prisms are typically formed by a series of small prisms molded into thin plastic sheets, a prism ridge side across one surface, and smooth and flat on the other.

When a prism is positioned in front of the eye, the retinal image is shifted towards the bottom of the prism. This can be the image jump which causes the eye to move in the direction of the apex of the prism to align the fovea with the new image location. In normal vision, both eyes work in tandem by pointing at exactly the same image, simultaneously. Each eye collects distinct visual information to be delivered to the brain for processing. The mind then combines the visual input from each eye to make a single image so you might see clearly.
