Many people experience small spots or threads drifting through their field of vision, commonly known as floaters. While often harmless, understanding what causes them and when they could be a sign of a more serious condition is crucial.
What are Floaters?
- Floaters are small, shadowy shapes that appear in your field of vision. They can look like spots, threads, or cobweb-like structures and are particularly noticeable against bright backgrounds. They move as your eyes move and seem to dart away when you try to look at them directly.
The Causes of Floaters
- The most common causes of floaters are age-related changes to the vitreous, the gel-like substance inside your eyes. As you age, the vitreous slowly becomes more liquid, and tiny fibers within it can clump together, casting shadows on the retina.
When to Be Concerned
- Sudden Increase in Floaters: A sudden increase in the number of floaters, especially if accompanied by flashes of light, could indicate a retinal tear or detachment, which requires immediate medical attention.
- Changes in Vision: If floaters are accompanied by changes in peripheral vision or a decrease in overall vision, it’s essential to seek medical advice as soon as possible.
Diagnosis and Treatment
- If you’re concerned about floaters, an optometrist or ophthalmologist can conduct a comprehensive eye exam to determine their cause and whether any treatment is needed.
- In most cases, no treatment is necessary for floaters. However, if they severely impair your vision, options like laser therapy or a vitrectomy can be considered.
Conclusion
Floaters are a common visual phenomenon, usually not a cause for concern. However, if you experience a sudden increase in floaters or other changes in your vision, it’s essential to get your eyes checked promptly.
