You’re not alone if you’ve ever noticed flashes of light or colored streaks after rubbing your eyes. The unique interaction between our eyes and brains is what causes this perplexing occurrence.

The Electrical Ballet of the Retina

When we rub our eyes, the retina, the light-sensitive layer at the back of the eye, briefly bursts into electrical activity. A series of events are triggered by this abrupt rush of electrical signals, creating an amazing visual extravaganza that captures our attention.

The Chemical Symphony of the Brain

The electrical activity of the retina causes our body to release neurotransmitters like serotonin and dopamine. These neurotransmitters are well recognized for controlling pleasure and emotion, but they also play a part in the fascinating visual effects that occur when we touch our eyes.

Beyond Eye Rubbing: Entoptic Phenomena

It’s interesting to note that other causes can also produce entoptic events, which are similar visual phenomena. These intriguing displays of light and color can be brought on by specific medications, health issues, a sharp drop in blood pressure, and other factors.

Carefully Scrubbing Your Eyes

Despite how engaging these visual displays are, it’s important to be cautious when wiping your eyes. Too much or too frequently rubbing your eyes might irritate the sensitive nerves and cause irritation. In extreme circumstances, this could impair vision. It’s crucial to treat your eyes gently and to only rub them when absolutely required.

A Wonderful Performance

Take a moment to admire the amazing spectacle your brain puts on for you the next time you want to rub your eyes. The complexity of our visual system is demonstrated by the symphony of electrical activity and chemical reactions.


Our visual system is amazing, as evidenced by the flashes of light and colors we see when we rub our eyes. Understanding the underlying mechanisms serves as a reminder to take good care of our eyes and to value the complex operations of our senses.
