Reading vs watching.
What changes when you blink?
Same face. Same camera. Two different activities. Explore your own blink pattern in about a minute, plus setup.
Does the activity change your blinking?
Read a short passage and watch a gentle animation for 30 seconds each. Your webcam counts natural blinks while your face is visible, then compares your two observations.
- Place your device at a comfortable distance in good light.
- Read or watch normally. There is no target blink count to aim for.
- See your counts side by side, and share only if you want to.
Camera frames stay on your device. Only numerical results are saved in this browser. Sharing and downloads are optional.
How this blink experiment works
The webcam detects short eye closures followed by reopening during a reading passage and a gentle animated scene. Each activity needs 30 seconds with your face visible. The timer pauses when your face leaves the frame, the camera stalls, or you switch tabs. Activity order is randomized when you start.
Live blink counts and the first result stay hidden until both activities finish, so there is no number to chase. Afterward, you see the observed counts and the equivalent blinks per minute. A 30-second count is simply doubled to express that rate.
What your comparison can tell you
It describes these two short activities. It does not establish your normal blink rate, diagnose dry eyes, or measure concentration. Camera quality, glasses, lighting, activity order, and awareness of the test can change the observations. Repeat if you are curious; there is no good or bad score.
The watching scene is generated in your browser and needs no video download. It respects reduced-motion settings, which makes the scene still and can change the comparison. Blink naturally and stop whenever you want.
