Hi there,
Welcome to HCM.I think your flashes are normal.
I have seen patients who experience
floaters for the first time become anxious,until reassured by the doctor.Floaters happen commonly as a natural aging process and they are harmless.But the doctors tell you to keep an eye on them as sudden increase in the number and size of floater along with frequent flashes may be an early sign of Retinal pathology.
It is very usual for any normal person to notice those flashes at times when moving your eyes quickly side to side ,due to the quick visual reflex perceived by our eyes.
So I would suggest you to wait and observe.If you notice them even when you are relaxed and frequently bothering you with decreased/
blurred vision then donot hesitate to get an early appointment.
Otherwise, as time passes by you will start ignoring your floaters which most of my patients do.When asked they say,"Yes I do notice ocasionally and it doesn't bother me".
So,I would say do not worry at the moment.
Hope this answers your question.Take care.
