“…A typical problem with such systems is the inconvenience and fatigue experienced by the user, often because of the disparity between the displayed synthetic imagery and the eye's natural vision. Enhancing simulated renderings with cues, such as chromatic aberration [15,41] and depthdependent blur [32,[99][100][101], can help alleviate this disparity. These techniques attempt to enhance the presented imagery with aberrations that are natural to the wearer's vision, using vision simulation and considering the inherent visual aberrations of the user to achieve the best possible results.…”

Vision-simulated imagery―the process of generating images that mimic the human visual system―is a valuable tool with a wide spectrum of possible applications, including visual acuity measurements, personalized planning of corrective lenses and surgeries, vision-correcting displays, vision-related hardware development, and extended reality discomfort reduction. A critical property of human vision is that it is imperfect because of the highly influential wavefront aberrations that vary from person to person. This study provides an overview of the existing computational image generation techniques that properly simulate human vision in the presence of wavefront aberrations. These algorithms typically apply ray tracing with a detailed description of the simulated eye or utilize the point-spread function of the eye to perform convolution on the input image. Based on the description of the vision simulation techniques, several of their characteristic features have been evaluated and some potential application areas and research directions have been outlined.
