Tateye is a prototype of eyeglasses using two built-in lasers to tattoo a chosen image on your eye retina. This device allows customers to see symbols of their choice always and everywhere. The selection can be made from various simple forms ( visual design ) depending on consumer wishes.

Tateye is a part of the series of ironic speculative prototypes. Made as a real, functional product, even if it entered mass production, Tateye would violate legal regulations endorsed to protect consumers  health and personal rights. By designing fictional products, the author speculates about possible future markets. Prototyping fictional objects stands as one of the common ways to materialize concepts and narratives of the speculative design. The embodiment of the speculative scenarios is particularly important for achieving public suspension of disbelief about possible futures.
