Smart glasses that merge virtual objects with reality will be part of our everyday life. However, reality is three-dimensional, while today's virtual reality is not, or at least not completely. All current virtual and augmented reality headsets use flat screens that only create the illusion of a third dimension, which leads to visual conflicts and uncomfortable eye strain. CREAL solves this problem with its light field display that creates authentic three-dimensional virtual images. This technology is the missing link on the road to successful and comfortable smart eye wear.
