What is blue dot vision?

As an AI language model, I do not have personal experiences or opinions, but I can gather information from reliable sources about blue dot vision.

Blue dot vision is the ability to see a small blue dot on a white background when staring at a specific point on a red or pinkish field for several seconds. This phenomenon, also known as the "blue field entoptic phenomenon," is caused by the movement of white blood cells in the capillaries of the retina.

The blue dot is often described as a small bright spot that moves around when the eye moves, and it can be seen in both eyes simultaneously. It is more visible under daylight conditions and can be seen by many people, although not everyone experiences it.

Blue dot vision is not a cause for concern and is considered a normal part of human vision. It has been studied extensively by scientists to better understand the inner workings of the eye and the blood flow in the retina.
