Hello dear and welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Your flashes seem to be related to orbicular migraine.
More details are needed to help me through the diagnosis.
When did these flashes of lights start?
Do you see them in one eye or both eyes?
Do you have any other medical condition such as diabetes?
Do you take any medications?
I would also recommend a retinal examination to exclude a retinal tear or detachment.
I will be waiting for your response to be able to help you better.
Hope I have answered your query.
Let me know if I can assist you further.
