What are the causes of eye floaters in a 23yo female doesnt happen all the time?

Have your eyes: examined and make sure there is nothing significant going on. However, floaters are very common, they are little tissue remnants. They are annoying, but we just live with them. You get used to them over time. You urgently need to see an eye doctor if your vision is impaired by them, if you notice flashes of light in your peripheral vision or you have pain with your floaters.
