Long hours at a screen make it easy to forget your body. SitBlinkSip keeps an eye on three simple things so you don't have to.

The Science
Why blinking matters when you work at a screen.
Blinking is one of the eye's natural ways of maintaining the tear film across the ocular surface. During prolonged digital-device use, blinking behavior can change — and reduced or incomplete blinking has been associated with dry-eye symptoms and digital eye strain.

01
Blinking changes during screen use
Research has identified altered blinking patterns as one factor associated with digital eye strain and dry-eye symptoms during prolonged digital-device use.
Digital Screen Use and Dry Eye: A Review
Read the research02Reduced blinking can affect the tear film
Reviews describe decreased blink frequency as an important factor in ocular surface dryness, since longer gaps between blinks can let the tear film break up before the next blink.
Digital Eye Strain: Updated Perspectives

A randomized controlled trial evaluating blink-reminder software reported improvements in blink rate and dry-eye-related symptom scores among visual display terminal users.

Digital eye strain has multiple contributing factors. Blinking behavior is one part of the picture, alongside things like prolonged near-focus work, visual demands, environmental conditions, and individual eye health. SitBlinkSip focuses on blink awareness as one simple, measurable habit that can support healthier screen-time routines — it doesn't diagnose, treat, or cure eye conditions.
That's where SitBlinkSip comes in.
Instead of waiting until your eyes feel tired, SitBlinkSip helps you become more aware of your blinking habits while you work.
