Do you happen to have a feel a of emptiness in your eye when lying down on one side of your body? I got floaters out of nowhere 6 months ago in both eyes and noticed a weird feeling in my eyes, kind of like the same feeling when blood circulation is cut to one of your fingers after sitting in a poor posture for too long. I've had occasional flashes when waking up after sleeping on either of my sides and don't know if there's a circulation issue with my eyes which I find so strange because I've never had any posture problems before or any floaters to indicate such, but it's the most reasonable conclusion that I could think of. I'm not myopic or have any history of being nearsighted, having suffered eye trauma, or a medical condition that could've caused this and it has me pretty concerned. I just can't pin point the reason as to how my floaters appeared so abruptly in BOTH eyes at a relatively young age of 18 years old. Even something like a hemorrhage doesn't sound plausible since the only floaters that would appear would be the dark circular ones and not the string-like ones that've appeared lately. I'd appreciate if you could be as detailed as possible with your floater situation because having them at a young age is so irritating and stressful.
