Screens and your tear film

Concentrating on a screen cuts how often you blink, and your tear film evaporates while you stare. It explains why eyes can feel dry by the end of a working day spent at a monitor.

Why blinking matters

Each blink spreads a fresh tear film across the surface of the eye. Fewer blinks leave more time for it to evaporate in between.

The oil layer

The outermost layer of the tear film is oil, responsible for minimizing evaporation of the watery layer beneath it. Quell is designed to reinforce that oil layer to help reduce moisture loss. More in the tear film’s oil layer.

Screen days and the directions

The directions don’t change with your schedule: Apply 1 drop 3 times per day in each eye. Tying doses to fixed points in the workday, like lunch, can make them easier to remember.

When it is more than tired eyes

Screens are one everyday reason for dryness, not the only one. The label says when to stop and get advice: Stop use and ask a doctor if you feel eye pain or changes in your vision, if irritation or redness continues, or if the condition worsens or persists for 72 hours.
