Squiggly threads drifting across my vision

You look at a bright sky or a blank wall. Thin squiggles or threads drift across your sight. They slide away when you try to look straight at them.

Most people call these floaters. They are tiny clumps inside the clear gel that fills your eye. The clumps cast small shadows on the back of your eye, and you see the shadows.

That gel turns more watery as you get older. So floaters are common past the age of 50. Being short-sighted, past eye surgery, or a knock to the eye can bring them on sooner.

When to see someone

See an eye doctor the same day if a shower of new floaters turns up at once. Flashes of light, or a dark curtain over part of your sight, need urgent care. Sudden blurring, eye pain, or new floaters after a blow to the head also need a check.

Below is a list of things people have long used for eye floaters. Each item has a grade that shows how much research has looked at it. A higher grade means more study, not a promised result, so talk with your eye doctor before you try anything new.

Eye Floaters: natural remedies and the evidence behind them

9 options · 2 graded C · 7 traditional or ungraded

How would you like to approach your eye floaters?

I'd like to start with supplements that have actually been tested in people with floaters

Bromelain
Centuries of traditional use· Limited human trials so far (Evidence grade C · Traditional use long-standing)Long-standing traditional staple
Pineapple-derived enzyme studied for floaters
Why this matches
If you want an internal option, bromelain is a pineapple-stem enzyme taken as a capsule that has actually been studied in people with vitreous floaters.
Why try it
In a double-blind trial, an oral enzyme blend led by bromelain was linked to a dose-dependent reduction in the number of floaters over three months. Bromelain was the main enzyme, and it may help break down the vitreous debris behind floaters - though it was tested alongside other enzymes rather than on its own, so the evidence is promising but not definitive.
Dose or use
Taken as an enteric-coated capsule, often standardized in GDU or MCU units; follow product labeling and take between meals for a whole-body rather than digestive effect.
Time to results
Gradual over about 1 to 3 months of daily use
Key study
Randomized controlled trial (2022, PMID 36431188): A New Pharmacological Vitreolysis through the Supplement of Mixed Fruit Enzymes for Patients with Ocular Floaters or Vitreous Hemorrhage-Induced Floaters - bromelain was the lead enzyme (190 mg) in a blend with papain and ficin, so the benefit cannot be attributed to bromelain alone.
Caution
May thin the blood and interact with blood thinners and some antibiotics, and can trigger reactions in people allergic to pineapple. Use caution before surgery and check with your doctor if pregnant or on medication.
Grape seed extract
Centuries of traditional use· Limited human trials so far (Evidence grade C · Traditional use long-standing)Long-standing traditional staple
Antioxidant seed extract from a floater-tested formula
Why this matches
If you'd like an internal antioxidant option, grape seed extract supplies the same Vitis vinifera proanthocyanidins used in a nutrient formula that was tested in people with floaters.
Why try it
Grape seed extract is rich in proanthocyanidin antioxidants that help protect small blood vessels and tissue from oxidative stress. A 6-month trial of a micronutrient formula containing grape-derived Vitis vinifera extract reported less visual discomfort and smaller vitreous opacity areas - though grape seed was one of several ingredients rather than tested alone, so its individual contribution is uncertain.
Dose or use
Taken as a standardized capsule or tablet; follow product labeling.
Time to results
Typically a few months of daily use
Key study
Randomized controlled trial (2021, PMID 34647961): Dietary Intervention With a Targeted Micronutrient Formulation Reduces the Visual Discomfort Associated With Vitreous Degeneration - grape-derived Vitis vinifera extract was one of several ingredients in the formula, so the effect cannot be attributed to grape seed alone.
Caution
May mildly thin the blood and lower blood pressure; use caution with blood thinners or before surgery, and check with your doctor if pregnant or on medication.

I prefer hands-on approaches - acupressure I can do at home or acupuncture with a practitioner

Acupuncture
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Practitioner-based session targeting eye health
Why this matches
If you're comfortable seeing a practitioner, acupuncture is a hands-on traditional therapy best explored with a licensed professional.
Why try it
Traditionally used in Chinese medicine to support circulation and energy flow to the eyes, acupuncture is thought to promote overall eye vitality.
Dose or use
Seek a licensed acupuncturist; a typical course is several weekly sessions over a few weeks.
Time to results
Typically several weeks with regular sessions
Key study
Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
Caution
Seek a licensed acupuncturist; inform them of any bleeding disorders or blood-thinning medications.
GB20 (Fengchi) - Gallbladder 20
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Acupressure point at the base of the skull
Why this matches
If you'd like something hands-on you can do yourself, GB20 is an acupressure point you can press at home.
Why try it
In traditional Chinese medicine, GB20 - in the hollows at the base of the skull - is used to ease eye strain and improve circulation to the head and eyes.
Dose or use
Press each point with a thumb for 1-2 minutes using firm, steady pressure; repeat daily as comfortable.
Time to results
May feel some relief right away; regular practice over weeks
Key study
A traditional acupressure point for eye strain; its effect on floaters has not been tested in controlled clinical trials.
Caution
Use gentle pressure and avoid the area if you have a neck injury or broken skin; stop if it causes dizziness or pain.

I want to dig into possible root causes, like a nutrient shortfall affecting my eyes

Vitamin C Deficiency
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
Low vitamin C may weaken vitreous collagen
Why this matches
If you'd like to look at possible internal causes, checking your vitamin C status is a simple place to start.
Why try it
Vitamin C is concentrated in the eye's fluid and is needed to build the collagen that gives the vitreous gel its structure, so a shortfall is a plausible contributing factor worth ruling out.
Dose or use
Ask your doctor about testing; correct through vitamin C-rich foods such as citrus, peppers, and berries, or a supplement if you are low.
Time to results
Weeks to months if a deficiency is corrected
Key study
Correcting a deficiency is general nutritional support; a direct effect on floaters has not been confirmed in controlled clinical trials.
Caution
High-dose supplements can cause digestive upset and may raise kidney-stone risk in prone individuals; favor food sources first.
Vitamin E Deficiency
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
Antioxidant that shields eye tissue from stress
Why this matches
If you want to consider internal factors, vitamin E status is another simple thing to check.
Why try it
Vitamin E is a fat-soluble antioxidant that helps protect the retina and other eye tissue from oxidative stress, and its deficiency guide explicitly names eye disorders, so a shortfall is a reasonable factor to consider.
Dose or use
Ask your doctor about testing; obtain vitamin E from nuts, seeds, and vegetable oils, or a supplement if you are low.
Time to results
Weeks to months if a deficiency is corrected
Key study
Correcting a deficiency is general antioxidant support; a direct effect on floaters has not been confirmed in controlled clinical trials.
Caution
High-dose vitamin E can thin the blood; avoid large doses if you take blood thinners or are approaching surgery, and consult your doctor.

I'd rather take a daily herb or antioxidant that supports overall eye health

Bilberry Extract
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Eye-health berry rich in antioxidant anthocyanins
Why this matches
If you'd like an internal option, bilberry is a berry extract you can take daily to support eye health and the small-vessel circulation that nourishes the eye.
Why try it
Bilberry's anthocyanins are potent antioxidants traditionally used to support the eyes and strengthen the tiny blood vessels feeding the vitreous and retina.
Dose or use
Taken as a standardized capsule or extract; follow product labeling or a practitioner's guidance.
Time to results
Typically several weeks of daily use
Key study
Traditionally used to support eye health; its specific effect on floaters has not been confirmed in controlled clinical trials.
Caution
May lower blood sugar and mildly thin the blood; use caution if you are diabetic, taking blood thinners, or approaching surgery.
Astaxanthin
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Potent carotenoid antioxidant for eye strain
Why this matches
If you prefer an internal supplement, astaxanthin is a once-daily antioxidant capsule aimed at eye and cellular health.
Why try it
Astaxanthin is a carotenoid with strong antioxidant activity, traditionally used to ease eye strain and reduce the oxidative stress linked to age-related changes in the vitreous gel.
Dose or use
Taken as a soft gel or capsule with a meal; follow product labeling.
Time to results
Typically several weeks of daily use
Key study
Reported to reduce eye strain; its effect specifically on floaters has not been confirmed in controlled clinical trials.
Caution
Generally well tolerated; may slightly lower blood pressure and interact with blood-pressure or immune-modulating medications - check with your doctor first.
Curcumin
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Anti-inflammatory herb taken as a supplement
Why this matches
If you prefer an internal, daily-use option, curcumin fits naturally into a supplement routine you can try at home.
Why try it
Traditionally used for its anti-inflammatory and antioxidant properties, curcumin is thought to support eye tissue health by helping reduce oxidative stress.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically several weeks to a few months
Key study
Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
Caution
May interact with blood thinners; consult your doctor if pregnant or on medications.

Evidence grades describe the strength of published research for Eye Floaters, not a promise of results. Nothing here is medical advice — talk to your clinician before starting anything, especially alongside prescription medication.
