Yes, many people experience seeing thousands of little star-like dots or specks when it is dark. This phenomenon is known as "visual snow" or "visual static." These dots or specks may appear as tiny flickering or shimmering points of light and are often more noticeable in low-light conditions or when looking at plain, dark surfaces.
Visual snow is considered a neurological condition, and individuals who experience it might see the visual disturbance persistently or intermittently. It can sometimes be associated with other visual symptoms, such as halos, afterimages, or light sensitivity.
The exact cause of visual snow is not fully understood, but it is believed to be related to abnormal processing in the visual system of the brain. Some researchers suggest that it could be linked to hyperexcitability of certain visual neurons, leading to the perception of the tiny dots or static.
While visual snow itself is not considered harmful, it can be bothersome and affect a person's quality of life, particularly if it is severe or accompanied by other visual symptoms. If you or someone you know is experiencing visual snow or any concerning visual disturbances, it is essential to seek an evaluation from an eye care professional or a neurologist to rule out any underlying medical conditions and determine the appropriate course of action.
