Green · Comfortable
Gentle daily tips
20–20–20 rule: Every ~20 minutes, look 20 feet away for 20 seconds.
Blink more: Screens make us stare. Consciously blink when your eyes feel dry.
Light & screen: Avoid a dark room with a very bright screen. Reduce glare where you can.
Hydrate & sit well: Water + posture make long screen days kinder to your eyes.
Important: BlinkCheck is not a medical device and does not diagnose or treat any eye condition.
If you have sudden vision changes, eye pain, a dark patch, wavy lines, flashes of light, or symptoms that worry
you, please book a proper eye examination with an eye care professional.
Bonus visual mini-games (optional)
Tiny, non-medical mini-games inspired by contrast checks, grids and color-dot puzzles.
They don’t change your BlinkCheck score and are not diagnostic.
Bonus mini-game · Contrast Spotter
One of the grey boxes below is a little darker. Tap the one you think is darkest.
This is just a fun screen contrast game, not a real vision test.
Tap a box to take a guess.
Bonus mini-game · Lines Checker (not a test)
This small grid is just a visual example. If you ever see bent lines, missing
patches, or dark spots in your real vision, please get a proper eye exam.
This mini-game cannot diagnose anything.
Cover one eye, look at the center dot for a few seconds, then repeat with the
other eye. In your everyday life (not just this grid), have you recently noticed
straight lines looking bent, broken, or a dark patch in your vision?
Your answer here won’t change your BlinkCheck score. It’s just a reminder to
pay attention to your own vision.
Bonus mini-game · Color Dot Guess
Inspired by color-dot puzzles. A number is hidden in the dots below. Your screen,
brightness and lighting change how this looks — this is not a
color blindness test.
