Vitreous Flashes & Floaters

At Florida Vision Centers, we provide physician-led eye care for patients in Estero, Bonita Springs, Naples, and Fort Myers who are concerned about new floaters, flashes, or sudden visual changes.

Seeing spots, cobwebs, threads, or drifting shadows in your vision?

Floaters are very common, especially as the eye changes with age. In many cases they are harmless. But a sudden increase in floaters, especially when paired with flashes of light, a shadow, or a curtain in your vision, can be a warning sign of a retinal tear or retinal detachment and should be evaluated promptly with a dilated eye exam. (AAO)

What Are Eye Floaters?

Floaters are small shapes that seem to drift across your field of vision. People often describe them as:

  • Specks
  • Dots
  • Cobwebs
  • Threads
  • Squiggly lines
  • Shadowy spots

They are often caused by small clumps or strands inside the vitreous, the gel-like substance that fills the middle of the eye. What you notice are the shadows these tiny structures cast on the retina. (AAO)

Many floaters are more noticeable when looking at a bright, plain background such as a blue sky, a white wall, or a computer screen. They may seem to move when your eyes move and drift away when you try to look directly at them. (AAO)

Are Floaters Normal?

Often, yes. Floaters commonly become more noticeable with age as the vitreous changes over time. A common age-related cause is posterior vitreous detachment (PVD), when the vitreous separates from the retina. This process can cause a sudden increase in floaters and sometimes flashes of light. Most cases are not dangerous, but they still may need an exam to rule out a retinal tear. (National Eye Institute)

When Are Floaters an Emergency?

You should seek prompt eye evaluation if you notice:

  • A sudden shower of new floaters
  • Flashes of light
  • A dark shadow in your side vision
  • A curtain or veil over part of your vision
  • New floaters along with blurred vision or decreased vision

These symptoms can be associated with a retinal tear or retinal detachment, which may threaten vision if not treated quickly. (National Eye Institute)

Flashes and Floaters: Why They Matter

Flashes can happen when the vitreous pulls on the retina. Floaters and flashes together may occur with vitreous detachment, but they can also be the first warning signs of a retinal tear. That is why any new or rapidly changing floaters deserve careful attention rather than being dismissed as routine aging. (National Eye Institute)

How Floaters Are Evaluated

At Florida Vision Centers, evaluation of floaters typically begins with a discussion of:

  • When the floaters started
  • Whether they appeared suddenly or gradually
  • Whether flashes are present
  • Whether there is any shadow, curtain, or loss of vision

dilated eye exam is important because it allows the retina to be examined for signs of a retinal tear, retinal hole, vitreous traction, or retinal detachment. (National Eye Institute)

Treatment for Floaters

Treatment depends on the cause.

In many patients, floaters are related to age-related vitreous changes and do not require urgent treatment. Some become less noticeable over time as the brain adapts and the floaters settle. But if floaters are caused by a retinal tear or detachment, treatment may be needed urgently to protect sight. (National Eye Institute)

When to Call Right Away

Please contact an eye doctor promptly if you have:

  • New floaters that appear suddenly
  • Floaters with flashes
  • A curtain, shadow, or missing area in vision
  • A noticeable drop in vision

These symptoms should not wait for a routine eye exam. (National Eye Institute)

Frequently Asked Questions

Floaters may look like tiny dots, cobwebs, strings, squiggles, or drifting shadows in your field of vision. (AAO)

Sometimes no, but sometimes yes. Longstanding stable floaters are often benign. A sudden increase in floaters, especially with flashes or a curtain in vision, can signal a retinal tear or detachment. (National Eye Institute)

They may not disappear completely, but many become less noticeable over time. Persistent or suddenly changing floaters should still be evaluated. (National Eye Institute)

Yes—especially if they are new. Floaters and flashes together can be associated with vitreous detachment, retinal tear, or retinal detachment, and a dilated eye exam is important. (National Eye Institute)
