Why do i have white shadowy floaters in my eye?

Vitreous detachment: Vitreous is a gel that fills the eyes and is attached to the retina when we are born. Depending on a lot of factor this almost always slowly gets detached from retina in everyone. Some sooner some later. Then the collagen fibers of the vitreous gel that used to be attached to retina and cast no shadow will show as usually greyish floaters. But you must see an eye md to rule out a retinal tear.

Floater...: What you are seeing as a floater is really a shadow cast from something floating inside your eye. Floaters are most often benign, but can possibly be serious. You should have a complete eye exam from an eye md.

Flashes & floaters: The clear gel that fills eyeball is normally attached to all parts of the inside of the eye. As we get older it can become more liquid (watery) and detaches from the back of the retina causing flashes & floaters. This can indicate a retinal tear. As the retina detaches, change or loss in your side vision is the next symptom. You should see your eye doctor to check the retina.
