Eye Floaters & Flashes Explained

Eye floaters and flashes are common visual symptoms that many people experience at some point in their lives. While they are often harmless, they can sometimes be a sign of a more serious retinal condition.


At Retinal Treatment Center, we help patients in Bradenton and Sarasota, FL understand these symptoms and determine when further evaluation is necessary.

What Are Eye Floaters

Floaters are small shapes that appear in your vision and seem to drift as your eyes move.

 

They may look like:

  • Spots or dots
  • Strings or cobwebs
  • Shadowy shapes that move across your field of vision
Floaters are caused by tiny clumps or changes in the vitreous gel inside the eye.

What Are Flashes of Light

Flashes appear as quick streaks or flickers of light, often in your peripheral vision.

 

They are typically caused by:

  • The vitreous pulling on the retina
  • Mechanical stimulation of retinal cells
Flashes may come and go and are often more noticeable in dim lighting.

Why Do Floaters & Flashes Happen

The most common cause is natural aging changes in the eye.


As the vitreous gel shrinks and shifts, it can:

  • Create shadows (floaters)
  • Pull on the retina (flashes)

This process is known as posterior vitreous detachment (PVD) and is usually not dangerous.

When Floaters & Flashes May Be Serious

Although many cases are harmless, sudden or severe symptoms can indicate a retinal problem.


You should take symptoms seriously if you notice:

  • A sudden increase in floaters
  • Persistent flashes of light
  • A shadow or curtain over your vision
  • Sudden vision loss
These may be signs of conditions like Retinal Tear / Retinal Hole or Retinal Detachment, which require urgent care.
