Just like any lens its job is to focus light.
A good example would be a pair of eyeglasses. They correct the vision by focusing light onto the eye

Lenticular and printing.

When interlacing, we take a slices from multiple images and arrange them to fit behind the lens. In this example we take slices from 4 different images and place each in order behind the lens. The lens will then focus on each different frame as the lens or users moves. The resolution of a lenticular file is a direct result of the number of lenses per inch multiplied by the number of frames used. In this case we have 4 frames, if we have 100 lenses per inch the result will be a 400 DPI file.

How flip works.

When the lens is oriented horizontally to the user, the lens allows the user to see only one frame at a time as it is turned up and down. The result is the illusion of animation as the lens focus goes across each individual image slice.

How 3D works.

When the lens is oriented vertically to the user, the lens allows the user to see two frames at the same time. Each eye sees a different frame. We see 3D naturally because we have two eyes. Lenticular simply takes advantage of this to provide us with the illusion of depth.
