Abstract
A method and apparatus for evaluating blue-light-radiation injury to a retina, a computer device and a medium. The method includes: acquiring a current environmental brightness and a current middle-grayscale brightness of a displaying device; according to a weighted blue-light-radiation-exposure value of a current environment, current environmental brightness, a weighted blue-light-radiation-exposure value of displaying device and current middle-grayscale brightness of displaying device, determining a device-environment factor; according to device-environment factor and current environmental brightness, determining an optimum middle-grayscale brightness of the displaying device in the current environment; according to the current middle-grayscale brightness of displaying device, the optimum middle-grayscale brightness of the displaying device in the current environment and the weighted blue-light-radiation-exposure value of the current environment, determining a current retina weighted blue-light-radiation-exposure value; and according to comparison between the current retina weighted blue-light-radiation-exposure value and a retina blue-light maximum safety-tolerance value, determining whether an eye-protection safety standard is satisfied.
