Handheld Vision Screener is the one that can be used as a quick and accurate tool to screen subjects for visual acuity deficits, being highly sensitive, specific, and cost-effective. It is extensively used in clinics to evaluate vision in immobile or sick patients or when the test distance is short. The effect of horizontal acceleration on human visual acuity and stereopsis is demonstrated using Handheld Vision Screener.
