Eye floaters.
A clearer understanding.

If these are new floaters, contact an eye-care professional today for urgent assessment. Do not assume sleep caused them. A sudden shower of spots, flashes, a dark curtain or reduced vision needs immediate eye care or an emergency department.

A sudden burst of new floaters, especially with flashes, a dark shadow or curtain, or a missing or blurry area of vision, can signal a retinal tear or detachment. Seek care right away. Do not wait for these symptoms to settle.

Yes. First-time or suddenly appearing floaters still need urgent assessment, even without flashes. The absence of flashes does not tell you that the retina is healthy. An eye examination can establish the cause.

New floaters in one eye still need prompt examination. Vitreous changes can occur in one eye before the other, but a retinal problem can also affect a single eye. Which eye is involved does not establish whether the cause is harmless.

A dark curtain or shadow covering part of your vision can be a sign of retinal detachment. This is an emergency warning sign, especially with new floaters or flashes. Go to an eye doctor or emergency department immediately.

Do not postpone a sudden change until a routine appointment. Contact an eye-care service for urgent assessment. With a curtain, loss of vision or a sudden shower of floaters, seek care immediately; use an emergency department if urgent eye care is unavailable.

New floaters or flashes after an injury or eye surgery need urgent advice. Contact the treating eye team or an urgent eye-care service. Tell them what happened and when; do not assume the change is a normal part of recovery.

Floaters with these symptoms can occur with inflammation inside the eye, such as uveitis. Blurred vision can occur too. See an eye doctor right away: untreated inflammation can damage vision, and symptoms alone cannot identify the cause.

Eye floaters are shapes that appear to drift across your vision. They often come from tiny clumps in the vitreous, the clear gel inside the eye, casting shadows on the retina. They are usually inside the eye, rather than something on its surface.

People often describe floaters as a moving thread, a strand of hair, worm-like squiggles or a cobweb that seems to hang in front of the eye. They may slide away when you try to focus on them. These can be shadows from material in the vitreous gel, rather than an actual hair. A new shape still needs assessment; its appearance cannot rule out a retinal problem.

A small drifting dot can be a floater: some people describe it as a fly that is not really there. Other floaters look like circles or clouds. A sudden shower of dark dots is different from an old, unchanged spot and needs urgent assessment, especially with flashes or reduced vision.

Vitreous floaters are inside the eye, so blinking or rinsing the eye does not remove them. This is different from a loose eyelash on the surface. If you are unsure what you are seeing, an eye examination can distinguish a floater from another problem.

Sources: National Eye Institute: Floaters

Do not assume that it is. Typical floaters drift with eye movement, while a dark or blurry area in your side or central vision can be a warning sign of retinal detachment. A new shadow, missing patch or loss of vision needs immediate eye care.

Sources: National Eye Institute: Floaters · National Eye Institute: Retinal detachment

They move as your eyes move, so trying to focus on one can make it seem to slip away. They may keep drifting briefly after your eyes stop moving. This movement is characteristic of floaters, but it does not replace an examination.

Bright, plain backgrounds make floater shadows easier to notice. Seeing familiar floaters against a bright morning background does not necessarily mean more have formed. However, new floaters on waking should be treated as a new symptom, rather than explained away by the light.

A Weiss ring is a circular or oval floater that can appear when the vitreous separates around the optic nerve during posterior vitreous detachment. A ring-like shape is not a diagnosis: a new ring still needs an eye examination.

Floaters are drifting shapes or shadows. Flashes are perceived flickers or streaks of light; pulling on the retina as the vitreous changes can produce them. New flashes, with or without floaters, warrant urgent eye assessment.

Migraine can cause temporary visual patterns, flashing lights or blind spots. Migraine aura usually affects both eyes; retinal migraine usually affects one. Do not self-diagnose a first or different visual episode as migraine. New visual symptoms, especially vision loss, require medical assessment.

Age-related changes can make strands in the vitreous gather together and cast shadows. Other causes include inflammation, bleeding, injury, vitreous detachment and retinal tears or detachment. The cause determines whether monitoring or treatment is needed.

PVD happens when the vitreous gel pulls away from the retina at the back of the eye. It becomes more common with age and may cause new floaters or flashes. An examination checks whether it has also caused a retinal tear or another complication.

Sources: National Eye Institute: Vitreous detachment

No. In vitreous detachment, the gel separates from the retina. In retinal detachment, the retina itself lifts from its normal position. Many vitreous detachments have no serious complication, but similar symptoms mean you need an examination to tell the difference.

Yes. Vitreous detachment is more common later in life, but it can occur earlier in people who are nearsighted. Being young does not make sudden floaters safe to ignore. New symptoms need assessment at any age.

Diabetic retinopathy can damage retinal blood vessels. Bleeding into the vitreous may cause floating dark spots or cobweb-like streaks. Seek care right away for these changes, even if they start to clear; diabetes-related bleeding can recur and needs treatment.

Yes. Uveitis is inflammation inside the eye and can cause floaters, blurry vision, redness, pain or sensitivity to light. It can affect one or both eyes and may need prescription treatment. An eye doctor should assess these symptoms promptly.

Previous cataract surgery is a risk factor for floaters, and floaters may become more noticeable afterward. New or suddenly increasing floaters should still be reported urgently to your eye team so they can check for a retinal problem.

The doctor usually examines the vitreous and retina after using drops to widen your pupils. A dilated examination helps check for retinal tears and other causes. Your symptom history matters too, including when the change began and whether your vision is affected.

It is usually painless. To look for a retinal tear, the doctor may press gently on the eyelids, which can feel uncomfortable. Tell the clinician if you are uncomfortable or anxious so they can explain each part of the examination.

Sometimes. If the vitreous is difficult to assess, the doctor may use optical coherence tomography (OCT) or ultrasound alongside the examination. The tests depend on what the clinician needs to see; not everyone with floaters needs every type of scan.

Dilation can blur your vision and increase light sensitivity for a few hours. Arrange a ride home and bring sunglasses. Do not drive while your vision is affected, even if the appointment itself was short.

You may. Your eye doctor will set a follow-up plan based on the findings and your risk factors. Follow-up checks can be recommended during the first few months. New or worsening symptoms should be reported urgently rather than saved for that appointment.

Contact your eye-care team urgently for new or worsening floaters, flashes, a curtain or reduced vision. An earlier reassuring examination does not rule out a later change. Keep the follow-up plan, but do not wait for it if symptoms worsen.

After an uncomplicated vitreous detachment, floaters often become less noticeable over a few months, but may not disappear completely. There is no fixed timetable for everyone. Return for advice if symptoms remain disruptive, and seek urgent help for a sudden change.

Screen use can contribute to dry-eye symptoms such as burning or blurred vision. Vitreous floaters arise inside the eye and are a different issue. Do not assume new drifting spots are simply screen strain or dry eye; have them assessed.

After an examination confirms uncomplicated PVD, many ordinary activities can continue. Advice about heavy lifting, high-impact exercise or inverted positions varies. Ask your ophthalmologist about your own retinal risk and any temporary restrictions, especially soon after symptoms begin.

Reading and computer use can usually continue after uncomplicated PVD has been assessed. Driving depends on whether your vision is safe and meets local requirements. If floaters interfere with seeing clearly or concentrating on the road, stop driving and ask your eye-care professional for advice.

Tell your eye doctor specifically what you cannot comfortably do. Persistent, disruptive floaters deserve a discussion even after retinal problems have been excluded. Observation may still be appropriate, but a specialist can discuss whether treatment benefits outweigh its risks in your case.

No. Age-related floaters that do not significantly affect you often need no treatment after assessment. When another condition causes them, that condition may need treatment. A reassuring diagnosis and a plan for new symptoms are different from ignoring an unexplained change.

There is no established eye-drop treatment that removes the vitreous changes of uncomplicated PVD. Drops may treat a separate problem, such as dry eye or inflammation, but that does not make them a general floater cure. Use prescription drops only as directed.

Vitrectomy is surgery to remove the vitreous gel and its opacities. It may be considered for severe, persistent floaters that interfere with everyday vision. It is not a routine first step for a newly noticed floater; an examination and specialist discussion come first.

Sources: American Society of Retina Specialists: Vitrectomy for floaters

Vitrectomy can cause cataract, retinal tears or detachment, retinal swelling and, rarely, vision loss. Your surgeon should explain your individual risk and the likely benefit. The decision should reflect how much floaters affect you as well as the examination findings.

A small randomized trial of 52 patients found improvement in selected Weiss ring floaters over six months. That does not establish that laser works for every floater or settle long-term safety. The researchers called for larger, longer studies; discuss suitability and risks with a retina specialist.

Some clinical research has reported benefits. In the six-month FLIES randomized, placebo-controlled trial involving 61 patients, the group taking the studied micronutrient formula reported less floater-related visual discomfort and had a reduction in measured vitreous opacities. These encouraging results come from one small study of a specific formula, so results may differ with other formulations and from person to person. Discuss suitability with your eye-care professional. Sudden new floaters, flashes or a shadow across your vision need urgent assessment.

A balanced diet supports general health. Clinical nutrition studies use specific formulations and doses; eating a food such as pineapple is not equivalent to taking the supplement studied. Your eye-care professional can help you consider nutrition alongside your examination findings, medicines and other care.
