I asked by eye doctor why there was so much mucus around my eyes and after she dumped in a little dye she noted my eyes were almost like sandpaper from not blinking enough. This seems like something that could have a technical solution beyond just putting liquid in your eyes. I am wary as liquids are sometimes contaminated with bacteria or other substances. Perhaps screens or headbands that trigger blink reactions.
