Eye Floaters‘Floaters’ are the little dots and shadows that float across your vision. Sometimes floaters will go through your eye and you won’t even notice, because your brain is hard-wired to adapt your vision to environmental changes. Other times, floaters can be quite alarming. Dots and lines going across your vision might make it difficult to concentrate and cause confusion, and the rest of your vision can become blurry if you’re worried and focusing on the floaters.
