Eye floaters are small specks, dots, strands, or cobweb-like shapes that drift through your vision, especially when you look at a bright sky, white wall, or computer screen. Common causes of eye floaters include normal age-related changes in the vitreous, nearsightedness, eye inflammation, previous eye injury, eye surgery, or a retinal tear. Most floaters do not signal an emergency, but a sudden increase in floaters, flashes of light, blurry vision, eye pain, or a curtain-like shadow in your side vision can mean you need urgent retina care.
What Are Eye Floaters?
Eye floaters form when tiny clumps of collagen or debris drift through the vitreous—the clear, gel-like substance filling your eyeball—and cast shadows on the retina. They move as your eyes move and may look like:
Specks or dots
Threads or strands
Cobwebs or squiggly lines
Common Causes of Eye Floaters
The cause of eye floaters usually starts inside the vitreous, the clear gel that fills the eye. As that gel changes, shrinks, or pulls on the retina, you may notice shadows that look like drifting spots or strands. Some causes are harmless, while others need prompt evaluation from a retina specialist.
Aging-Related Vitreous Changes
As you age (typically after 50), the vitreous gel naturally liquefies and pulls away from the retina, forming microscopic clumps that appear as floaters.
Myopia (Nearsightedness)
Higher degrees of nearsightednessincrease vitreous traction on the retina, leading to more floaters among myopic patients.
Inflammatory eye conditions release white blood cells into the vitreous, creating spots and strands that become visible floaters.
Astigmatism (Corneal Irregularities)
Uneven curvature of the cornea in astigmatism alters how light enters the eye. Research shows that those with moderate to high astigmatism often notice floaters sooner and more frequently than people with perfectly spherical corneas.
Retinal Tears & Detachments
A sudden surge in floaters, especially with flashes of light or a dark curtain in your side vision, can signal a retinal tear or retinal detachment. These symptoms require urgent evaluation because the retina can detach from the back of the eye, threatening vision. If you notice these changes, contact Barnet Dulaney Perkins Eye Center right away or seek urgent eye care.
Eye Injury & Surgery
Trauma or surgical procedures (e.g., cataract surgery) can introduce blood cells or other debris into the vitreous, leading to floaters.
When to See a Doctor
Most eye floaters result from normal vitreous changes, but certain symptoms may indicate a retinal problem that requires prompt attention.
Schedule an eye exam right away if you notice:
A sudden increase in new floaters
Flashes of light
A dark curtain, veil, or shadow in your vision
Loss of side vision
New blurry vision with floaters
Floaters after an eye injury
Floaters with eye pain, redness, or light sensitivity
These symptoms do not always indicate a retinal tear or detachment, but you should not delay in seeking treatment. A prompt dilated eye exam can help your doctor check the vitreous and retina before a small problem becomes more serious.
How Eye Floaters Are Diagnosed
During your exam, your eye doctor will:
Dilate your pupils to fully inspect the vitreous and retina.
Perform slit-lamp biomicroscopy to examine the front structures of the eye.
Use indirect ophthalmoscopy to check the peripheral retina for tears or detachments.
Order OCT imaging if high-resolution retinal scans are needed.
If your exam shows a retinal tear, detachment, bleeding, inflammation, or another retina concern, your doctor may connect you with Barnet Dulaney Perkins Eye Center’s retina specialists for advanced evaluation and treatment.
Treatment & Management Options
Observation & Reassurance
Mild Floaters: Often settle out of the central vision over weeks to months—no treatment needed.
Procedure: Surgical removal of the vitreous gel and floaters, replaced with saline.
Benefits: Immediate and complete removal of floaters.
Risks: Retinal detachment, cataract formation, infection—reserved for severe cases.
Preventive & Supportive Measures
Regular Eye Exams: Early detection of retinal tears prevents serious complications.
Protective Eyewear: Safety glasses during sports or work reduce trauma-induced floaters.
Healthy Lifestyle: Control diabetes and hypertension to lower the risk of vitreous hemorrhage.
Know When Floaters Need A Closer Look
Eye floaters can be harmless, but sudden changes should be evaluated. If you notice new floaters, flashes of light, blurry vision, or a curtain-like shadow, schedule a comprehensive eye exam with Barnet Dulaney Perkins Eye Center. Our team can evaluate your symptoms, examine your retina, and guide you toward the next step that best protects your vision.
FAQ: Common Eye Floaters
Common eye floaters are small specks, dots, lines, rings, or cobweb-like shapes that drift through your vision. You may notice them more when you look at a bright sky, white wall, computer screen, or another light background. Floaters often move when your eyes move and may drift away when you try to look directly at them.
Eye floaters often come from age-related changes in the vitreous, the clear gel inside the eye. As the vitreous shrinks or changes texture, it can cast tiny shadows on the retina. Floaters can also develop from nearsightedness, eye inflammation, eye injury, bleeding inside the eye, previous eye surgery, or retinal tears.
You should worry about eye floaters if they appear suddenly, increase quickly, or happen with flashes of light, blurry vision, loss of side vision, eye pain, or a curtain-like shadow in your vision. These symptoms can point to a retinal tear or retinal detachment and need prompt eye care.
Yes, eye floaters can become more common with age because the vitreous gel naturally changes over time. Many age-related floaters do not need treatment. However, new or changing floaters should still be checked, especially if they appear suddenly or come with flashes, shadows, or vision loss.
Some floaters become less noticeable over time as they settle or your brain learns to ignore them. Others may remain visible, especially in bright lighting. Even if floaters seem mild, a dilated eye exam can help confirm that your retina looks healthy.
An eye doctor usually checks floaters with a dilated eye exam. Dilation allows your doctor to look at the vitreous, retina, and optic nerve more carefully. Your doctor may also use retinal imaging or other testing if they suspect a retinal tear, detachment, bleeding, or inflammation.
Yes, eye floaters can sometimes signal a retinal tear, especially when they appear suddenly or come with flashes of light. A retinal tear can lead to retinal detachment if it does not receive prompt treatment. That is why sudden floaters should never be ignored.
Treatment depends on the cause. Many floaters only need monitoring if the retina looks healthy. If your doctor finds a retinal tear, retinal detachment, bleeding, or inflammation, you may need retina care. Your eye doctor will explain the safest next step based on your exam results.
Yes. Barnet Dulaney Perkins Eye Center evaluates eye floaters for patients across Arizona. If you notice new floaters, flashes of light, blurry vision, or a shadow in your vision, schedule an eye exam so the care team can check your retina and guide your next step.
