About this tool
Build a posture-reset and 20-20-20 eye-break schedule for a long study session, with a live timer that flags each break.
This tool builds a break schedule for a long study session — 20-20-20 eye breaks every 20 minutes, a posture reset roughly every 30 minutes and a stand-and-move break each hour — and runs a live timer that tells you when each one is due. It follows the American Academy of Ophthalmology's 20-20-20 rule and standard ergonomics guidance on breaking up seated work. It is built for students facing multi-hour study days who want the breaks decided in advance instead of relying on willpower.

Defaults follow the 20-20-20 rule and hourly sit-break guidance, and every interval is adjustable.
Overlapping eye, posture and stand breaks are combined so you pause once, not three times.
Start the timer when you sit down and it shows exactly which break is next and in how long.
Every 20 minutes of screen or close-up work, look at something about 20 feet (6 metres) away for at least 20 seconds. The rule is promoted by the American Academy of Ophthalmology and the American Optometric Association as a simple way to reduce digital eye strain during long study sessions.
Roughly every 30 minutes, reset your posture for 30 to 60 seconds — feet flat, shoulders relaxed, screen at eye level — and at least once an hour stand up and move for a couple of minutes. Ergonomics guidance, including the UK HSE's display screen equipment advice, favours frequent short pauses over rare long ones.
No — the breaks scheduled here total only a few minutes per hour. A 20-second eye break and a 45-second posture reset are micro-pauses; research on sustained attention suggests brief interruptions can help maintain focus across a long session rather than break it.
When two intervals land on the same minute — for example the 60-minute mark hits the eye, posture and stand intervals together — the tool merges them into one pause, and only the longest break counts toward total pause time, because you can do the eye break while standing.
