What Are Eye Floaters and What Should I Do About Them?

Have you ever noticed specks, threads, or cobweb-like shapes drifting across your field of vision? These peculiar visual phenomena are called eye floaters, and whilst they might seem alarming at first, they're quite common. Understanding what causes them, how to manage them, and when to seek professional help can provide peace of mind and protect your precious eyesight.

 What Are Eye Floaters?

Eye floaters are small, moving spots that appear in your vision, particularly noticeable when looking at bright, uniform backgrounds like a clear sky or white wall. They're caused by tiny clumps of cells or protein that form in the vitreous—the clear, jelly-like substance that fills the inside of your eye. As light passes through your eye, these clumps cast shadows on your retina, creating the appearance of floating objects.
The Science Behind the Shadows

The vitreous humour makes up approximately 80% of your eye's volume and is crucial for maintaining the eye's shape. As we age, this gel-like substance naturally begins to shrink and become more liquid, a process called vitreous syneresis. During this change, microscopic fibres within the vitreous can clump together, creating the shadows we perceive as floaters.

Most floaters develop gradually as part of the natural ageing process, typically becoming more noticeable after age 50. However, they can occur at any age due to various factors including myopia (short-sightedness), eye inflammation, or previous eye surgery.

 Managing Your Floaters

Whilst floaters can be bothersome, particularly when reading or using computers, most are harmless and don't require treatment. The brain often adapts to their presence over time, making them less noticeable. However, several management strategies can help:

**Lifestyle adaptations** include avoiding sudden head movements that might make floaters more apparent, and using good lighting when reading to reduce eye strain. Some people find that gently moving their eyes up and down or side to side can shift floaters out of their direct line of vision temporarily.

**Dietary considerations** may also play a role. Maintaining adequate hydration and consuming foods rich in antioxidants, such as leafy greens and omega-3 fatty acids, may support overall eye health; however, direct evidence for reducing floaters is limited.

 When Professional Help Is Essential

Whilst most floaters are benign, certain symptoms warrant immediate attention from an optometrist or ophthalmologist. The NHS advises seeking urgent eye care if you experience:

- A sudden increase in the number of floaters
- Flashing lights in your vision
- A shadow or curtain moving across your field of vision
- Sudden vision loss

These symptoms could indicate serious conditions such as retinal detachment or vitreous haemorrhage, which require prompt treatment to prevent permanent vision loss.

The Importance of Regular Eye Examinations

Regular check-ups with a qualified optometrist are crucial for maintaining eye health and detecting changes early. UK guidelines recommend eye tests every two years for most adults, or annually for those over 70 years old or those with existing eye conditions.

During a comprehensive eye examination, your optometrist can distinguish between harmless floaters and potentially serious conditions. They may perform dilated eye examinations or optical coherence tomography (OCT) scans to assess your retinal health thoroughly.

Remember, your vision is irreplaceable. Whilst floaters are usually nothing to worry about, any sudden changes deserve professional evaluation. Don't hesitate to contact your local optometrist if you have concerns—early detection and treatment can make all the difference in preserving your sight for years to come.
