Key Takeaways
- Eye floaters can become more noticeable with age as the gel inside the eye naturally changes.
- Occasional, stable floaters are often not linked to a serious eye problem.
- A sudden increase in floaters, particularly with flashes or a shadow in your vision, needs prompt eye assessment.
- The appearance of floaters can have several causes, so their pattern and timing matter.
- An eye examination can help determine whether monitoring is appropriate or further investigation is needed.
You notice a small dark spot drifting across your vision. You look directly at it, but it seems to move away. Then you look elsewhere, and there it is again. For many people, this is an eye floater.
Floaters are small shapes that appear to move through your field of vision. They may look like dots, threads, cobwebs or wispy lines. They are often easier to notice when looking at something bright and plain, such as a white wall or the clean sky. So, are they simply part of getting older?
Why do eye floaters become more noticeable with age?
Inside the eye is a clear, gel-like substance called the vitreous. It helps maintain the eye’s shape and allows light to pass towards the retina, the light-sensitive layer at the back of the eye. As we age, the vitreous can gradually become more liquid and change in structure. Small strands or clumps within it can cast shadows onto the retina. What you see as a floater is often the shadow of these structures.
This is one of the common causes of eye floaters, particularly as people get older. A floater that has been present for a long time and remains relatively unchanged may not require treatment. However, assuming every new floater is harmless can be unwise.
When is a new floater worth taking seriously?
The change is often more useful than the floater itself. For example, there is a difference between occasionally noticing one familiar floater and suddenly seeing many new spots or strands.
New floaters can sometimes occur when the vitreous pulls away from the retina, a process known as posterior vitreous detachment. This can happen with ageing and does not necessarily mean that the retina has been damaged. However, the traction involved can sometimes cause a retinal tear.
A retinal tear may progress to retinal detachment, which can affect vision and requires urgent medical attention. You should consider seeking prompt eye assessment if floaters appear suddenly, especially if they occur with,
- Flashes of light in your vision
- A sudden increase in the number of floaters
- A dark curtain, veil or shadow across part of your vision
- A noticeable loss or reduction of vision
These symptoms do not automatically mean you have a retinal tear or detachment. They do mean that an examination is appropriate rather than simply waiting to see whether the symptoms disappear.
Can something other than aging cause floaters?
Yes. The vitreous and retina can be affected by various eye conditions. Floaters may sometimes be associated with inflammation inside the eye, bleeding within the vitreous, eye injury or other retinal problems. People who are very short-sighted may also have a different risk profile for certain retinal conditions.
This is why an eye examination considers more than the appearance of the floater itself. Your age, eye history, vision changes and other symptoms can all provide useful context.
Do floaters always need treatment?
If an examination finds no concerning cause and the floaters are not significantly affecting your daily activities, your eye care professional may recommend observation.
Treatment decisions depend on what is causing the floaters, how much they interfere with vision and whether there is an underlying eye condition that needs attention. There is no single approach that is appropriate for everyone.
Frequently Asked Questions
1. Do eye floaters eventually disappear?
Some floaters become less noticeable over time as the brain adapts to them. Others may remain visible.
2. Are eye floaters a sign that my eyesight is getting worse?
Not always. Floaters can occur without a general deterioration in eyesight. However, a sudden change in floaters should be assessed.
3. Can I ignore a floater if I have had it for years?
A longstanding, unchanged floater may be less concerning, but new symptoms or changes should not be dismissed without assessment.
4. Are flashes and floaters always an emergency?
Clear vision does not necessarily mean every aspect of your eye health is normal. If retinal disease runs in your family, discuss this history with your optometrist even if you currently have no concerns.
5. Can eye floaters be prevented?
Age-related changes in the vitreous cannot necessarily be prevented. Protecting your eyes from injury and attending appropriate eye examinations can nevertheless be part of maintaining eye health.
Schedule a consultation
The important question is not simply, “Do I have floaters?” It is, “Have my floaters changed, and are there other symptoms?” If you have noticed new or changing floaters, particularly alongside flashes or a change in your vision, arrange an eye assessment promptly.
In Singapore, Stan Isaacs Optometrists, together with Dr. Stan Isaacs and his team can assess your visual symptoms and help determine whether further evaluation is appropriate. A floater may be an ordinary consequence of changes within the eye. But when something changes suddenly, it is worth finding out why rather than assuming it is simply ageing.
