Have you ever wondered about the small particles that can sometimes been seen floating across your field of view?

Especially when you are looking at a bright image or a solid white background, such as the sky on a cloudless day or your computer screen when it’s blank?

What are these moving objects, and what causes you to see them?

Small dots in your vision

The tiny dots in your field of vision are called eye floaters. They may look like grey fragments of dust, cobwebs or little strings that drift about as your eyes move, and then float away as suddenly as they appeared when you try staring at them.

Related to ageing

This mostly occurs due to ageing which takes place as the vitreous (jelly contents) inside the eye becomes more like a liquid, according to Ted-ed.com.

The minute fibres inside the vitreous tend to become thicker over time, which casts small shadows on the retina of your eye. These appear to the human eye as floaters.

If you notice an increase in the amount of times you see eye floaters, it would be wise to contact your optometrist or an eye specialist immediately – especially in the case of flashes of light or if you start losing your peripheral vision.
