I'm going to give you the short version. Flashes can be a symptom of a retinal tear, retinal detachment or a vitreous detachment, so it is extremely important that you see an ophthalmologist asap to have an evaluation for that. If everything looks totally normal then you may have some obscure situation like pressure phosphenes or other conditions that rarely have any dangerous implications. Again, see an ophthalmologist for a complete evalauation right away.
Generally, flashes of light are something you want to have an opthalmologist check out. It could be insignificant, but you sort of indicate this started rather suddenly just two years ago (not something you've had all your life, right?). I'd make an appoint with a doc.
