Blinking vs. Flickering: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on October 19, 2023
Blinking refers to the rapid opening and closing of the eyes, while flickering describes the rapid and irregular variation in the brightness of a light source.

Key Differences
Blinking and flickering, though seemingly similar in periodic motion, represent distinct concepts. Blinking primarily refers to the act of shutting and reopening the eyes quickly, a natural and necessary bodily function. It helps to moisten and clear out debris, ensuring that the eyes remain comfortable and can function correctly. Flickering, on the other hand, pertains to a light that quickly and irregularly varies in its brightness.

In everyday experience, one might notice blinking when observing people or animals, as it is an involuntary reflex that serves to protect and lubricate the eye. Flickering is most commonly associated with unstable lights, like a candle flame disturbed by a breeze or an old fluorescent bulb on the verge of burning out. It's more of a visual irregularity, often deemed undesirable in artificial lighting scenarios.

Blinking has evolved as a biological mechanism, serving critical roles like spreading tears across the eye surface and offering brief moments of respite from visual stimuli. Flickering, in contrast, is typically a byproduct of inconsistencies in a light's power source or the medium it's passing through.

The distinction is clear when you juxtapose the two: while blinking is a purposeful action or reflex of the eyelids, flickering is an unintended inconsistency in the illumination of a light source.
