A 20-20-20 timer for teachers.

Online teaching turned eye strain from a desk-job problem into an educator problem. Hours of Zoom or Google Meet, plus lesson planning, plus grading on the same screen — and the eye fatigue is real by the end of the school day. EYE CARE is a free 20-20-20 timer that runs in a browser tab during prep periods and grading sessions, giving your eyes the breaks they need without competing with student attention.

Why teachers feel it during remote and hybrid teaching

  • Video calls demand sustained near-focus on a screen at fixed distance — a worse load on the ciliary muscle than in-person teaching, where the eyes naturally roam.
  • Lesson planning and grading layer additional close-up screen work on top of contact hours; the daily screen exposure of an online teacher often exceeds that of a knowledge worker.
  • Younger students model their habits on what they see; building the 20-20-20 rule into your teaching day quietly demonstrates good screen hygiene to your students.

How to use it during a school day

Run EYE CARE during prep periods, grading sessions, and asynchronous teaching time. During live classes, you can either pause the timer or let it run silently — the audio cue is soft enough to ignore if you are mid-explanation. Some teachers actively share the 20-20-20 rule with their students and run breaks together; the social cue helps the habit stick for everyone. The timer is in 12 languages, including the ones most-spoken by ESL students, if you want to share the link with families.

What it cannot fix

Eye strain in teachers is often compounded by glare from poorly positioned ring lights, low monitor resolution, or laptop-screen-at-laptop-distance setups. Invest in an external monitor at proper distance and a small camera-mounted softbox; the eye fatigue you save translates directly into how you feel at 5 PM.

Common questions

Will it work on a school-issued Chromebook?
Yes — EYE CARE runs in Chrome on Chromebook with no install required. Just open eyecare.love.
Can I share this with my students?
Yes. The tool is free and available in 12 languages. Many teachers send the link with a short note about why eye care matters during long screen days.
Will it disrupt a live Zoom or Meet session?
The break overlay only appears in the EYE CARE browser tab — your Zoom window is unaffected. You can also press Esc to skip a break during a class moment.
Is it appropriate to recommend to students for studying?
Yes. The American Optometric Association recommends the 20-20-20 rule for anyone using screens for more than two hours daily; a school-age child easily exceeds that.
