When light enters the eye, these clumps get in the way and cast shadows onto the retina. The collagen fibres within the vitreous humour also begin to clump together and can float freely in the now-watery surroundings. It then starts to degenerate with age, and its consistency becomes less gelatinous and more liquid. Once we reach adulthood, formation of the vitreous is complete. The vitreous humour is a jelly-like substance, made up mostly of water along with small amounts of salts, sugars, collagen and proteins. Light travels through the lens to the retina, where it is transmitted to the brain for processing into the image that you see.īefore the light gets to the retina, it has to travel through a transparent viscous fluid that sits between the two structures and fills the back of the eye – this fluid is called the vitreous humour. The lens is at the front of the eye and the retina is at the back of the eye. To understand what an eye floater is, you need to know some basics about how the eye works.

And it’s common to have several floaters of different shapes and sizes at the same time. They can look like dots, flecks, threads, cobwebs or even clear little bubbles. If you try to focus your vision on them, they may seem to move or float about.įloaters come in various shapes and sizes. Floaters are particularly obvious when looking at a clear sky or a white wall. As you look around, they follow your eye movements and drift through your field of vision, often with a slight delay. Eye floaters are tiny spots or threads in your vision.
