Have you ever noticed tiny spots, squiggly lines, or shadows drifting across your vision? Floaters are common, and while they’re often harmless, a sudden increase or new appearance can signal a serious eye problem.
In this blog, we’ll discuss what eye floaters are, why they happen, and why it’s important to schedule a comprehensive eye exam.
What do eye floaters look like?
Floaters may look like small dots, thread-like strands, or spiderweb patterns that move as your eyes move. They can appear to dart away when you try to focus on them.¹
You’ll notice floaters more when looking at bright backgrounds, such as a white wall or a clear sky. Even though they appear in front of your eyes, they form inside the vitreous, the gel-like substance that fills the eye.
Common causes of eye floaters
Most floaters develop naturally as the vitreous changes with age. Tiny fibers within the gel can clump together, casting shadows on the retina that appear as floaters.
Other causes include¹:
- Inflammation in the back of the eye: Conditions like posterior uveitis, which can result from infections, autoimmune disorders, or other inflammatory issues, may leave tiny particles in the vitreous that appear as floaters.
- Bleeding inside the eye: Blood cells from retinal tears, diabetes, high blood pressure, blocked vessels, or injuries can show up as floaters.
- Retinal tears or detachment: When the vitreous pulls on the retina, it can create a tear. If left untreated, this may lead to retinal detachment and a sudden increase in floaters.
- Eye surgeries or medications: Certain procedures or injections can introduce small air or silicone bubbles in the vitreous. These bubbles can appear as floaters until the eye absorbs them.
When floaters may be dangerous
Most floaters are harmless, but a sudden change could signal a more serious issue. Reach out to our trusted optometrist in Plainfield or Naperville right away if you notice:
- A sudden surge in the number of floaters
- Flashes of light, like sparks or camera flashes
- Dark shadows or a curtain blocking part of your vision
- Floaters that appear after an eye injury
These signs may indicate a retinal tear or detachment, which requires prompt attention to help preserve your vision.
How optometrists evaluate floaters
During a comprehensive eye exam, your optometrist examines the back of your eye using specialized instruments. Pupil dilation or a digital retinal scan provides a detailed view of the retina and vitreous, helping detect tears, thinning, or inflammation early.
Everyone should get regular eye exams, regardless of their vision correction needs or risk factors. However, routine exams are even more critical if you are nearsighted, have a family history of retinal issues, or recently updated your glasses or contact lenses and noticed new floaters.
