Retina blue light radiation injury evaluation method and device, computer equipment and medium

Abstract

The invention discloses a retina blue light radiation injury evaluation method and a device, computer equipment and a medium. A specific embodiment of the method comprises the following steps: acquiring current environment brightness and current intermediate gray scale brightness of display equipment; according to the weighted blue light exposure value of the current environment, the current environment brightness, the weighted blue light exposure value of the display equipment and the current intermediate gray scale brightness, calculating to obtain an equipment-environment factor; taking the weighted blue light exposure value of the standard environment as the maximum retinal blue light safety tolerance value, and calculating the optimal middle gray scale brightness of the display equipment in the current environment according to the equipment-environment factor and the current environment brightness; according to the current middle gray scale brightness of the display equipment, the optimal middle gray scale brightness and the weighted blue light exposure value of the current environment, calculating to obtain a current retina weighted blue light exposure value; and comparing the current retina weighted blue light exposure value with the maximum value, and judging whether the eye protection safety standard is met or not.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a method and device for evaluating retinal blue light radiation damage, computer equipment and media. Background technique [0002] In the existing low-blue-light eye protection display standards, there are usually two ways to reduce the damage caused by blue light to the retina; one is to reduce the color temperature, that is, to reduce the content of blue light in white light, so as to achieve the effect of reducing blue light damage Another method is, since the blue light that is more harmful to human eyes is mainly short-wavelength blue light (400nm-450nm), the peak wavelength of blue light is shifted to the long-wave direction, thereby reducing the damage of short-wavelength blue light to human eyes. . The resulting eye protection safety standard is to test the proportion of blue light radiation in white light or the proportion of blue light in a specific ...

Problems solved by technology

Therefore, only reducing the relative content of blue light radiation cannot guarantee the absolute radiation amount of blue light reaching the fundus retina. In an indoor office environment, the pupil diameter of the human eye is small; therefore, under the same display brightness, the amount of blue light radiation reaching the fundus retina in a dark environment is much higher than that in an indoor office environment. much more damage

[0004] In order to promote sales, display device manufacturers have been working hard to increase the brightness and contrast of display devices to enhance visual stimulation, claiming that display devices use low blue light technology, by reducing the color temperature and / or shifting the peak wavelength of blue light to the long-wave direction Technical means make the display device have an eye-protecting effect; however, due to the lack of corresponding restrictions on the display brightness and consideration of the environmental impact, the amount of blue light radiation that actually reaches the retina is not necessarily reduced, which may cause higher eye fatigue and even damage the human eye. does more damage
