Have you ever noticed something floating in the corner of your eye?

Eye floaters, those tiny, drifting specks or shapes that occasionally move across your field of vision, are a common occurrence. While they are annoying, they’re nothing to worry about…most of the time. It’s important to be aware of what they are, what causes them, and when it’s a good idea to talk to an optometrist. 

What Are Eye Floaters?

Eye floaters are small, semi-transparent particles that appear to float or drift across your field of vision. They can take on various shapes, such as dots, lines, cobwebs, or clouds, and are most noticeable when looking at a bright, well-lit background, like a clear sky or bright wall. These visual disturbances can be distracting. Unfortunately, people tend to rub at their eyes when they experience floaters. Try to avoid this, as it can lead to further irritations or even injuries or infections. 

What Causes Eye Floaters?

Eye floaters are primarily the result of little chunks of protein or other cell debris within the vitreous humour, a clear, gel-like substance between the lens and the retina. These specks cast shadows on the retina, creating floaters’ appearance.

When can you expect to see eye floaters? 

They are most commonly a result of age. As we age, the vitreous humour gradually becomes more liquid, causing it to shrink and develop clumps or strands that cast shadows on the retina. This natural process is a leading cause of floaters in older individuals. You’ll typically start to notice more between fifty and seventy-five. They can also be more likely to occur if you are near-sighted or have had cataract surgery. 

Sometimes, younger people can experience eye floaters. This is often the sign of an underlying medical condition. These conditions can range in severity from simple infection to haemorrhage. Take action if you are young and experiencing vision changes. 

When Can Eye Floaters Be Dangerous?

While eye floaters are typically harmless and a normal part of the ageing process, they can occasionally result from more severe eye conditions that require prompt medical attention, especially if you are under 50. It is essential to consult with your optometrist if you notice certain symptoms. Sometimes, floaters are the result of retinal tears and detachment, bleeding in the eye, or infection and inflammation. Here are a few times you should take floaters seriously and contact your optometrist: 

Sudden onset of floaters: If you experience a sudden and substantial increase in floaters, especially if flashes of light or vision changes accompany them, seek immediate professional evaluation. This could indicate a retinal tear or detachment. 

Gradual increase in floaters: If you notice a gradual but persistent increase in the number or size of your floaters, schedule an appointment with your optometrist for an eye examination. While this may be a natural part of ageing, it’s crucial to rule out any underlying conditions. 

Changes in floaters: If you notice any changes in your floaters, such as their colour, shape, or behaviour, consult your optometrist. Such changes could suggest an underlying eye condition that requires attention. Be sure to explain when and where you see the floaters and how they have changed in shape. 

New or worsening symptoms: If floaters are accompanied by other symptoms like pain, redness, light sensitivity, or vision impairment, seek immediate medical care. 

When you visit Lethbridge Vision Centre for floaters concerns, we conduct a comprehensive eye exam. We will evaluate the floaters, check for any associated eye conditions, and determine the appropriate course of action. Treatment for eye floaters typically involves monitoring and education. We will ask you to track your floaters and symptoms and continuously monitor them as you return for follow-up visits. 

Eye floaters are a common visual phenomenon caused by small particles or debris in the vitreous humour. While they are typically a natural part of ageing and nothing to worry about, they can occasionally indicate more severe eye conditions. Understanding when to seek optometric care is crucial to maintaining optimal eye health and preserving your vision. Regular eye exams and prompt attention to changes in your floaters can help ensure that any underlying issues are identified and treated, providing you with peace of mind and the best possible visual outcomes.
