I keep getting flashes of lights in my eyes, mostly my left eye, that look like after burners - as if someone's just used their camera or I've looked at a bright light. So its kind of bright then fades to bluey colour and is more visible when I blink. Sometimes these are more like sparkles rather than lights.
I tend to get them more when I have been working out, running, or have just got up quickly or bent over.
They are totally different to the lights I get when I have a migraine - these appear at the top of my vision and tend to be zig zag and make me a bit blind! These ones are more in the bottom/centre of my vision near my nose.
They have been happening for at least 2 years now, at first I presumed they were to do with migraine so would either take pills as a precaution or neck a pint of water to avoid a migraine. But they never turn into migraines.
So then I thought maybe it was my glasses/vision so have had a brand new prescription done and a load of test and my eyes are completely normal - no retinal detachment!
My optician says it could be vascular.
Just wondering if anyone else has experienced this?
Slight worry about it being a brain tumor!!
