You're likely experiencing eye floaters, which can sometimes appear like ants or small insects in your field of vision.
Understanding Floaters
Floaters are small, dark shapes that drift across your vision. They can appear as:
- Specks
- Strings
- Cobwebs
- Shadows of insects, like ants
These shapes are usually shadows cast by tiny clumps of material in the vitreous humor, the gel-like substance that fills the inside of your eyeball.
Why Do They Appear Like Ants?
The way these floaters move and their small, dark appearance can often make people perceive them as ants or other insects. The specific shape a floater appears to have is subjective. The shape depends on the size and formation of the clump within the vitreous humor and how it refracts light.
Are Floaters a Problem?
Most of the time, floaters are normal and harmless. They are usually caused by age-related changes in the eye.
-
Normal floaters typically remain constant in number and size over time.
-
A sudden increase in floaters may indicate a more serious issue, such as:
- A tear in the retina.
- Retinal detachment.
- Bleeding within the eye.
- Inflammation in the eye.
As mentioned by the reference, "a sudden increase in their number may indicate damage to particular internal structures of the eye."
When to See a Doctor
While occasional floaters are common, you should seek immediate medical attention if you experience any of the following:
- A sudden increase in the number of floaters.
- Flashes of light.
- A curtain-like shadow or loss of peripheral vision.
- Any sudden change in your vision.
These symptoms can suggest a potentially serious condition that requires prompt treatment.
| Symptom | Action |
|---|---|
| Sudden increase in floaters | See a doctor |
| Flashes of light | See a doctor |
| Curtain-like shadow or loss of vision | See a doctor |
In summary, what you see as "ants" are very likely normal eye floaters that usually pose no threat, but you should see a doctor immediately if they are accompanied by other symptoms.
