This morning when I woke up my right eye was seeing everything blurry and it hasn't gone away. My other eye is fine. I don't have any other symptoms, no pain, no redness. It's worrying me quite a bit, should I go to the ER or is it not serious?
This is the kind of thing that could be harmless or not, and honestly you should get it checked out rather than just sitting around wondering about it. Sudden blurred vision in one eye only can come from tons of different things - sometimes it's just buildup of mucus or dry eyes (especially if you sleep weird or you're in an air-conditioned environment), but it can also be something like inflammation, an eye pressure problem, or even something more serious like retinal detachment in worst-case scenarios. The fact that you have zero pain and no redness is actually a pretty good sign, but that doesn't mean it's nothing.
Honestly, I think you should call your optometrist or doctor for at least a quick consultation, even if it's not an immediate hospital emergency. If you've got a walk-in clinic or an eye emergency clinic nearby, it's worth going today or tomorrow at the latest. If on top of the blurriness you notice flashes, weird floaters, or it's getting significantly worse, then yeah you go to the ER. But you're probably looking at "get it checked quickly" rather than "code red" territory. The main thing is don't ignore it for too long, because if it actually is something that needs treatment, the sooner you catch it the better.
