Lenticular

Lenticular eyeglass lenses are employed to correct extreme hyperopia (farsightedness), a condition often created by cataract surgery when lens implants are not possible. Lenticular printing is a multi step process consisting of creating a lenticular image from at least two existing images, and combining it with a lenticular lens. In general lenticular is a term for the lens effect that creates a convex perspective of multiple images or light sources. A lenticular lens is a single convex lens that magnifies light through a prism effect.
