In this article I will deal with optical illusion in Islamic art, one of the most important phenomenon in it. This phenomenon is also called the "Optical art"(1), which appeared in various artistic aspects such as the difference in view in accordance with the position of the viewer, far or near (with the variety of mass patterns). Abstractions can lead to a difficulty in determining the elements unless one concentrates while looking at the work of art. The extreme evolution of the designs of Arabic inscriptions, the extreme evolution of geometrical designs, and the interlacement between all decorations and the high ability in using the colours and their tones. All these things may lead to a difficulty in reading the piece of art; On the other hand, they add to the aesthetic value.
