We introduce a near eye light field display proposal to reconstruct a light field in high synthesis speed by utilizing the multi-layer light field display technology and human visual features. The resolution distribution of the reconstructed light field is set to be identical to human visual acuity which decreases with the increasing visual eccentricity. We compress the light field information by using different sampling rates in different visual eccentricity area. A new optimization method for the compressed light field is proposed, which dramatically reduces the amount of calculation. The results demonstrate that the acceleration of the proposed scheme is obvious and escalates when the spatial resolution increases. The synthesis scheme is verified and its key aspects are analyzed by simulation and an experimental prototype.
