What Are the White Dots We See When Looking at the Sky…?

Have you ever noticed tiny white dots moving when you gaze at the blue sky? This intriguing phenomenon isn’t related to stars, clouds, or atmospheric conditions but rather to how our eyes work. It’s called the “blue field entoptic phenomenon” or “white blood cell phenomenon.”

When you look at a bright surface, like the sky on a sunny day, light enters your eyes and illuminates the blood vessels in the retina. White blood cells, larger and more transparent than red blood cells, flow through tiny capillaries in your eyes. As they pass, they create subtle shadows that your brain interprets as moving white dots.

This occurrence is entirely normal and harmless. However, if you frequently notice other visual disturbances, such as dark or flashing spots, or experience vision problems, it’s a good idea to consult an eye specialist to rule out any underlying health issues.

The white dots are a fascinating reminder of how our bodies create unique visual experiences, offering a glimpse into the intricate systems that keep us functioning every day!
