I think I have Benign Eye Floaters?

Ok well i dont know how i got or since when have they been present with me, but for sure is been a loooooong time, probably when i was 12 or 13, right now iam 17. Everyday i have them, they are there and they never go away, nor do they ever change their spot in my eye. Its hard to explain them though, the majority of them look like bubbles all squished up together in random places all over the eye, and when i get my eye still they float downwards slowly. Also when i put my eyes together to see between my eyelashes i notice very small almost invisible "dots", and some "dots" are brighter and come out randmoly too but those are visible without any effort of me trying to see them. My vision is not at all affected by this as they are all transparent and i see right through them. Also, when i center my eye, right in the middle thers squiggly horizontal lines, also they float down too. And one more thing, it has happened but ITS VERY RARE WHEN IT DOES, is that i lose partial vision on my left eye, i describe tihs as a "flash" and it starts building up and then slowly wears away, like in a minute or two. Do i have bening eye floaters? if so, what can i do to get them off? are they something to be aware of? i never went to a doctor or something to check them out, because i thought it was no big deal and now they are part of my life i guess, but if they cant be removed i would like to know how, thanks everyone
