The Blue Field Entoptic Phenomenon, also known as "Blue Field Vision," is a visual phenomenon characterized by the perception of small, bright dots moving rapidly across a blue background, particularly when looking at a clear blue sky. These dots are not external objects; rather, they are the shadowy silhouettes of white blood cells moving through the capillaries in the retina.
