You are likely describing “photopsia”, which can express in many ways and is sometimes referred to as “seeing stars”. I myself call them “fairies”, as for me they are tiny rainbow scintillating spots that spiral around and disappear between 1-4 seconds. They are produced when a sudden shift in physical pressure on the retinal cells occurs. Blood pressure shifts are the cause when standing up or sitting down, and is typically a concern. They can also be produced by physical impacts against the eyes or head.
