About this timer: The 20-20-20 Rule & OSHA Workplace Eye Safety
Does OSHA require the 20-20-20 rule?
OSHA does not specifically mandate the 20-20-20 rule by name. However, OSHA's guidelines for computer workstation ergonomics recommend regular breaks from prolonged screen use, proper monitor positioning, and strategies to reduce visual fatigue. The 20-20-20 rule is one of the most practical ways to meet those guidelines, which is why many workplace safety programs include it.
What does OSHA say about computer eye strain?
OSHA's computer workstation guidelines address eye strain through recommendations on monitor placement (20–26 inches from the eyes, top of screen at or below eye level), lighting (to reduce glare and screen reflections), and work habits (taking regular breaks from screen work). OSHA also recommends that employers provide eye exams for workers who use computers extensively.
Can I share this timer with my team?
Yes. It runs in any browser with no account or installation needed. Share the link with your team and everyone can run their own timer. It's a simple way to implement eye break reminders across a team without installing workplace monitoring software.
Should employers implement the 20-20-20 rule?
It's a low-cost, high-impact measure. Computer Vision Syndrome affects productivity, increases sick time, and contributes to worker discomfort. Encouraging the 20-20-20 rule — and providing a simple tool like this timer — is one of the easiest workplace wellness initiatives a company can implement. Some organizations include it in their ergonomics training alongside desk setup and posture guidelines.
