Eye floaters are small moving spots that appear in your field of vision. They may be especially noticeable when you look at something bright, such as white paper or a blue sky.
They generally appear to dart away when you try to focus on them. Eye floaters can appear in many different shapes, such as black or gray dots, squiggly lines, threadlike strands, which can be knobby and semi-transparent, cobwebs, ring shaped. Once you develop eye floaters they usually do not go away, though they tend to improve over time. The vitreous and its millions of fine collagen fibers shrink and become shred-like. Shreds can accumulate in the vitreous.
The clear vitreous gel which completely fills the back of the eye earlier in life decreases in size and no longer can fill this space.
