What are flashes and floaters?

These visual disruptions are typically caused by tiny clumps of cells casting shadows inside your eye.

Floaters appear as:

• Dots, cobwebs, threads, or squiggly lines
• Gray or dark shapes that drift across your vision
• Objects that move when your eyes move and seem to dart away when you try to focus on them

Floaters are most noticeable when looking at bright backgrounds, like a blue sky or white screen.

Flashes look like:

• Brief streaks or flickers of light
• Lightning-like flashes in your peripheral vision
• Camera-flash sensations, even in a dark room

Flashes are usually more noticeable in low light or when moving your eyes quickly.

What causes flashes and floaters?

The most common cause of flashes and floaters is changes in the vitreous, the gel-like substance that fills the inside of the eye. Common causes include:

• Posterior vitreous detachment (PVD), which is a natural, age-related change
• Normal aging of the eye
• Nearsightedness (myopia)
• Previous eye surgery or trauma

As the vitreous shifts or separates from the retina, it can create floaters or tug on the retina, causing flashes.

Why can flashes and floaters be serious?

In some cases, flashes and floaters may indicate:

• Retinal tears
• Retinal detachment
• Vitreous hemorrhage
• Inflammatory or vascular eye conditions

These conditions can threaten your vision and require an urgent evaluation with Dr. Nix. Schedule an eye exam promptly if you experience:

• A sudden onset of flashes or floaters
• A noticeable increase in floaters
• Flashes accompanied by vision loss or shadows
• Any change that feels new or concerning

When it comes to retinal health, it’s always better to check sooner rather than later. 

How are flashes and floaters treated?

Dr. Nix offers prompt evaluation with a thorough examination and advanced retinal imaging to detect subtle tears or weak areas and determine whether you need treatment.

He may confirm that the flashes and floaters are from a routine vitreous change, and you can have peace of mind knowing your eyes are healthy. If an exam or imaging reveals a retinal tear or detachment, your treatment may include:

• In-office laser procedures
• Minor surgical interventions
• Advanced retinal procedures for more severe cases

If your vision has changed, Dr. Nix can help you understand what’s happening and take steps to protect your sight. Call Nix Eye Care and Surgery or book an appointment online to evaluate flashes and floaters today.
