01 / A COMMON SUGGESTION
What do 20 minutes, 20 feet and 20 seconds mean?
The familiar 20-20-20 suggestion is to take a break about every 20 minutes and look at something roughly 20 feet (6 metres) away for at least 20 seconds. The American Academy of Ophthalmology offers regular breaks as a practical way to reduce digital eye strain. The numbers are a memorable prompt—not a medical dose or a guarantee against eye disease.
A study of 30 young adults compared 20-second breaks at different intervals during a 40-minute tablet reading task. It found no significant differences between schedules in reported symptoms (P=.70), reading speed (P=.93) or task accuracy (P=.55). The study was small, brief and limited to one task, so it does not show that all breaks are ineffective. It also does not support presenting the exact formula as a proven treatment. A more careful use is as a reminder to pause near work.
Why make a reminder app?
When work holds your attention, it is easy to lose track of time. Gaze6m does one small thing: it offers a cue, then lets you decide whether to take a break, snooze or pause reminders.
It does not test your vision, assess your eyes or diagnose a condition. If discomfort persists or concerns you, seek advice from an eye-care professional.
