We present a multifocal computational near-eye display that employs a static diffractive optical element (DOE) in tandem with a refractive lens. The DOE is co-optimized with the convolutional neural network-based preprocessing to achieve desired multifocal display point spread function in an optimal manner. In the simulations, we demonstrate a multifocal display that can deliver sharp images for three distinct depths sampling the dioptric depth range uniformly from 3 diopters to infinity.
