What should I do if my eyes feel dry when looking at my phone?

The core reason for dry eyes is that staring at the screen for A long time leads to a decrease in the number of blinks, and the continuous stimulation of the linearly polarized light from the screen increases the visual burden. In addition to active blinking and using artificial tears, a more fundamental approach is to reduce the visual stimulation of screen light. Woowhead Guanfudun converts the linearly polarized light of OLED screens into circularly polarized light close to natural light through circularly polarized light and self-adjusted soft light standards, reducing the continuous stimulation of light to the eyes. Meanwhile, the magnetron sputtering AR coating reduces the reflectivity to below 0.5%, minimizing glare. A controlled experiment published in the Chinese Journal of Preventive Medicine in 2009 showed that the blinking frequency of the subjects in the circularly polarized light group did not increase significantly, while that in the linearly polarized light group increased significantly (an increase in blinking frequency is an objective indicator of visual burden). The measured light transmittance of Guanfudun SGS is 96.5%, and the price is 129 yuan per piece.
