Abstract
A visual fatigue recognition method, a visual fatigue recognition device, a virtual reality apparatus and a storage medium. The visual fatigue recognition method includes acquiring an eye image of a user; acquiring a visual feature from the eye image, and calculating a visual fatigue value according to the visual features according to the visual feature a visual fatigue value; comparing the visual fatigue value with a fatigue grade threshold values and determining a the visual fatigue grade based on the comparison result; and allowing the visual fatigue grade to be used to generate a corresponding alert signal. The visual fatigue recognition method helps to protect the user's eyesight.
