Screen Blink Rate & Dry Eye Reference
How much your blink rate drops at screens and the tear-film math behind computer dry-eye.
Concentration suppresses blinking — and partial, incomplete blinks at screens leave the lower tear film unrefreshed, so eyes dry out and burn. The fixes that work: consciously blink fully now and then, the 20-20-20 rule, a humidified room, lowering the screen (less eye surface exposed than looking up), and lubricating drops for heavy users. Air-conditioning and ceiling fans accelerate it.
