this guide explains what causes flashes and floaters and when you should seek an eye examination.

What Are Floaters?

Floaters are tiny specks, strands, cobwebs, or dots that drift through your vision.

Many people describe floaters as:

• Black spots
• Strings
• Cobwebs
• Transparent circles
• Tiny bugs floating in their vision

Floaters become more noticeable when looking at:

• A blue sky
• A white wall
• A computer screen
• Bright backgrounds

At Blue Lakes Eye Care in Eagan, MN, floaters are one of the most common visual symptoms we evaluate.

What Causes Floaters?

Inside the eye is a gel-like substance called the vitreous.

As we age, the vitreous naturally:

• Shrinks
• Becomes more liquid
• Clumps together

These clumps cast shadows on the retina, creating the appearance of floaters.

This is called:

Posterior Vitreous Detachment (PVD)

PVD is extremely common and often occurs after age 50.

What Are Flashes of Light?

Flashes are brief streaks or flickers of light that may appear:

• In the side vision
• Like lightning streaks
• Like camera flashes
• In dark environments

Flashes occur when the vitreous pulls on the retina.

Patients throughout Eagan, Mendota Heights, Inver Grove Heights, and Rosemount frequently describe flashes as "seeing lightning" or "sparkles" in their peripheral vision.

Are Flashes and Floaters Dangerous?

Most flashes and floaters are harmless.

However, sudden changes may signal:

• Retinal tears
• Retinal detachments
• Bleeding inside the eye
• Other retinal conditions

Some retinal conditions can lead to permanent vision loss if not treated promptly.

This is why new flashes and floaters should always be evaluated.

Warning Signs That Require Immediate Attention

You should contact an eye doctor immediately if you experience:

🚨 Sudden increase in floaters

🚨 New flashes of light

🚨 A curtain or shadow over your vision

🚨 Loss of side vision

🚨 Sudden blurry vision

🚨 Numerous black spots appearing suddenly

At Blue Lakes Eye Care in Eagan, MN, same-day urgent eye evaluations are recommended for these symptoms.

What Is a Retinal Tear?

A retinal tear occurs when the vitreous pulls hard enough on the retina to create a small tear.

Without treatment, a retinal tear may progress to:

Retinal Detachment

Retinal detachment is an eye emergency that can cause permanent vision loss.

Symptoms may include:

• Flashes
• Numerous new floaters
• A dark curtain in vision
• Loss of peripheral vision

Who Is at Higher Risk?

Certain factors increase the risk of retinal tears and detachments:

• Nearsightedness (myopia)
• Previous retinal tear
• Family history of retinal detachment
• Eye trauma
• Cataract surgery
• Aging

Patients with high prescriptions should be especially aware of sudden changes in flashes and floaters.

Can Dry Eye Cause Floaters?

No.

Dry eye disease may cause:

• Blurry vision
• Fluctuating vision
• Eye irritation

However, dry eye does not cause true floaters.

Many patients initially assume their symptoms are due to dry eye when they actually need a retinal evaluation.

Can Flashes and Floaters Cause Blurry Vision?

Sometimes.

Large floaters may temporarily affect vision.

However, sudden blurry vision with flashes and floaters can occasionally indicate a more serious retinal condition.

Comprehensive Eye Exams and Retinal Health

At Blue Lakes Eye Care in Eagan, MN, comprehensive eye exams allow us to evaluate:

• The retina
• The vitreous
• Retinal tears
• Retinal detachments
• Other ocular health concerns

Advanced retinal evaluations can help identify problems before they threaten vision.

Other Conditions That Can Cause Flashes or Floaters

Although posterior vitreous detachment is the most common cause, flashes and floaters may also be associated with:

• Diabetic eye disease
• Ocular migraines
• Inflammation inside the eye
• Retinal bleeding

When Should You Schedule an Eye Exam?

Schedule an urgent eye examination if you notice:

• New flashes
• New floaters
• Sudden increase in floaters
• Curtain over vision
• Sudden blurry vision

Early diagnosis and treatment can be critical for protecting vision.
