Why Do We Get Floaters in Our Eyes?

If you’ve ever noticed tiny specks, squiggly lines or cobweb-like shapes drifting across your vision, you’re not alone. These are known as eye floaters, and they’re one of the most common (and most Googled) visual experiences people have.

What Are Eye Floaters?

Floaters are small shadows cast on the retina by tiny clumps inside the eye’s vitreous — the clear, gel-like substance that fills the space between the lens and the retina. As light enters the eye, these clumps block parts of it, creating shapes that appear to float across your field of vision.

They often move when your eyes move and seem to dart away when you try to look directly at them.

Why Do They Appear?

The most common reason for floaters is ageing. Over time, the vitreous gel naturally begins to liquefy and shrink, causing microscopic fibres to clump together.

Other common triggers include:

• Natural changes in the eye with age

• Nearsightedness

• Eye strain or fatigue

• Previous eye surgery

• Inflammation inside the eye

In most cases, floaters are completely harmless.

When Should You Pay Attention?

While floaters are usually nothing to worry about, sudden changes should never be ignored. You should seek professional advice if you experience:

• A sudden increase in floaters

• Flashes of light

• A shadow or curtain across your vision

  
  

These symptoms can indicate changes at the back of the eye that need prompt assessment.

Living With Floaters

For many people, floaters become less noticeable over time as the brain learns to ignore them. Staying well hydrated, taking regular screen breaks and keeping up with routine eye examinations all help support overall eye comfort and health.

The Takeaway

Floaters may be annoying, but they’re usually a normal part of how our eyes change over time. Understanding what’s happening can be reassuring — and knowing when to seek advice is key.

If you ever notice changes in your vision or simply want peace of mind, a professional eye examination can help ensure everything is exactly as it should be.
