Full blinks — the habit behind dry eyes
The fix
A few times an hour, blink slowly and fully so the lids actually touch.
Why it happens
Concentrating suppresses blinking, and many of the blinks that remain are partial — the lids never fully meet. Only a complete blink spreads a fresh tear film across the whole eye surface.
If you ignore it
Chronic partial blinking leaves the lower eye surface exposed, driving the gritty, burning, tired-eye feeling of long screen days.
