“…With different polarization state, polarizationdependent lens can create different focal lengths and thus generate multiple focal planes for near-eye display. As electrically tunable lens is able to dynamically adjust the focus for the light, it can been combined with active shutters to achieve time-multiplexed focus adjusting for the virtual images and real images respectively (Liu et al, 2008;Xia et al, 2019). In this way, tunable lens based design can help to solve the VAC problem.…”

Optical see-through near-eye display (NED) technologies for augmented reality (AR) have achieved significant advancements recently with investments from both academia and industry. Although various AR NED products have been successfully commercialized and even deployed into applications, there are still challenges with present AR NED technologies (e.g., limited eyebox, fixed focus, bulky form factors). In this review, we present a brief overview of leading AR NED technologies and then focus on the state-of-the-art research works to counter the respective key challenges with each of the leading AR NED technologies. We also introduce a number of emerging technologies that are worthy of close study.

“…The VAC causes viewer fatigue and discomfort as well as distortions in the perceived depth [24,72]. Much research has been carried out in an attempt to solve the VAC issue in both VR and AR displays, which include varifocal displays (VR [32,36,38,55] and AR [1,10,15,18,30,75]), multifocal displays (VR [3,13,14,25,43,[50][51][52]61] and AR [4,16,41,42,44,60,65] ), light field displays (VR [23,26,39] and AR [46,48]), holographic displays (VR [11,12,49,58] and AR [30,47] ), and other display techniques, such as those that use color information [2,17]. Unfortunately, despite the substantial effort that has been put into solving the VAC for stereoscopic flat-panel displays and HMDs, researchers have not focused on the issue for stereoscopic PM.…”

Fig. 1. The proposed multifocal stereoscopic projection mapping technique mitigates the vergence-accommodation conflict by placing the virtual image (as an optical term) at the desired distance from an observer using focal-sweep active shutter glasses and a synchronized high-speed projector. (a) Prototype system; (b) experimental setup to show the multifocal appearance of Stanford bunnies onto a flat surface (D) whose virtual images were placed, from near to far, at points at which three physical objects (A-C) were placed; (c-e) captured scene observed through a focal sweep lens. The bunnies, as well as the physical objects, appeared focused from the bottom to the top according to the focus distance of the camera lens at (c) near, (d) middle, and (e) far.

“…Inserting additional optics to the near-eye display is a common solution considered by many previous studies. For example, studies [1][2][3][4] adopted an electrically-controlled focus-tunable lens to change the focal power as needed. Yet, this solution requires a complicated focustunable device and cannot deal with astigmatism and HOAs by only changing the focal length.…”

This study proposes a vision‐correcting near‐eye light field display, which computationally manipulates sampling rays according to an eye's refractive error. Besides myopia and hyperopia, the proposed method can correct astigmatism and high‐order aberrations without any hardware modification. Implementation and experimental verification are provided by taking a severely astigmatic eye as an example.
