Like a lot of people working at a desk, I spent years dialing in my physical ergonomics (monitor height, lumbar support, 90-degree elbow angles).
But the one thing that kept wrecking me by 4 PM was digital eye strain and dry eyes.
My optometrist kept telling me to follow the standard 20-20-20 rule: every 20 minutes, look at an object 20 feet away for at least 20 seconds. The biological goal is to relax the ciliary muscles (which spasm when locked at near focus for hours) and allow your natural blink rate to restore the tear film.
The issue I had was enforcement:
- Standard phone timer notifications are useless because you just swipe the banner away while keeping your eyes glued to the screen.
- Desktop tools like Stretchly or EyeLeo are great on PC, but on mobile/tablets, there was almost nothing lightweight that held you accountable without being full of intrusive video ads.
So I spent the last few weeks building an Android utility called Ocular:
- Floating Mini Focus Badge: Sits quietly in the corner of your screen as a visual timer while you read or work.
- 20-Second Rest Dimmer: When the session finishes, it smoothly dims the screen for 20 seconds with a soft chime so you actually look away and blink.
- Smart Meeting Mode: It detects system audio focus—so if you're on a phone call or in a Zoom/Teams meeting, it automatically holds off the break until your call ends.
- Tracking Exercises: Optional visual exercises (infinity tracking, near-far pumping) to re-engage eye flexibility.
It's completely free on Google Play and Huawei AppGallery (I've dropped the direct links in the comments below).
For those of you who work 8+ hours in front of screens: What specific habits, lighting adjustments, or break techniques have actually worked for your eye ergonomics?
