Is this something I should bring up with my family doctor the flashing lights and floaters or just see an Optometrist?
See your optometrist asap. I had a sudden bout of floaters about 15 years ago. Lots of them. When I was on the golf course on a sunny day they appeared like insects buzzing around me.
I immediately went to see my optometrist who told me I had a hole in the retina of my left eye.
He sent me to a specialist to do a laser repair, which was almost painless. Since then the occasional tiny floater, but nothing problematical. I do see my optometrist once a year, and he says my retina is fine, and the repair is holding up well.
As the old joke goes, but a true story in my case, I found if I rubbed my eye hard in the morning I sometimes would see a flash. The optometrist, after checking to ensure my optic nerve was fine, said "don't rub your eye hard..." lol
