I, too, experienced dry eyes and found it challenging to consciously blink regularly. A few years ago, someone gifted me one of these "3-D puzzles" (similar to this: https://www.amazon.ca/Bookend-Miniature-Bookshelf-Birthday-B...). I kept it on my desk and it helped me somewhat regulate my constant focus on the screen by prompting me to glance at it occasionally. That's just something that worked for me.
