Why am I seeing tracers when I look at lights at night?

Seeing tracers when looking at lights at night can be a symptom of a condition called visual snow. This condition is characterized by seeing static-like or moving visual disturbances, such as tracers or halos around lights. It is believed to be caused by abnormal processing of visual information in the brain. If you are experiencing persistent visual disturbances, it is recommended to consult with a healthcare professional for further evaluation and management.
