Quick answer
PCOS dry eye is real, but it is usually mild. A 2026 review pooled 13 studies with 639 women with PCOS. Women with PCOS reported more dry eye symptoms, and their tears broke up about 3 seconds sooner on one test. On most other tests, their eyes looked similar to the eyes of women without PCOS. Most did not meet the full criteria for dry eye disease.
- The likely weak spot is the oil layer of your tears. Tiny oil glands in your eyelids make that oil, and androgens act on those glands.
- An eye doctor can check with a symptom score, a tear break-up time test and a photo of your eyelid oil glands.
- Fish oil capsules did no better than an olive oil placebo in a 2018 trial of 535 people.
- The American Academy of Ophthalmology lists blink breaks, warm compresses and preservative-free drops as first steps.

Can PCOS cause dry eyes?
PCOS is associated with dry eye, but the link is mild and has not been proven to be cause and effect. Most studies compare women with PCOS to women without it at a single point in time, which researchers call a cross-sectional design. They usually find more irritated, gritty or burning eyes in the PCOS group. They also tend to find shorter tear break-up times and more damaged oil glands in the eyelids. That design cannot show whether PCOS itself caused those changes.
Dry eye disease is a condition where your tear film can no longer keep the surface of your eye moist and smooth. It can sting, burn or feel like sand in your eye. Your vision can also blur, then clear again when you blink. The National Eye Institute lists being female as a risk factor, along with extended screen time.
A note on names. PCOS is now also called PMOS (Polyendocrine Metabolic Ovarian Syndrome, the new name as of 12 May 2026). The eye studies all use PCOS, so we do too, and everything here applies to PMOS dry eye in the same way.
The practical takeaway: if your eyes feel dry and you have PCOS, an eye examination is worth booking. Do not assume it is "just hormones" and tolerate it.
What does the 2026 review on PCOS dry eye show?
The best summary so far is a 2026 systematic review and meta-analysis in Current Eye Research. It pooled 13 studies with 639 women with PCOS, compared with healthy women. Here is what it found, test by test.
| Test | What it measures | PCOS vs other women |
|---|---|---|
| OSDI score | How bad your symptoms feel, scored 0 to 100 | 7.5 points worse in PCOS |
| Tear break-up time with dye | Seconds before dry spots form after a blink | 3.1 seconds shorter in PCOS |
| Tear break-up time without dye | The same thing, measured by a camera | 2.1 seconds shorter, borderline (p = 0.05) |
| Schirmer test | Your production of watery tears | No clear difference |
The authors were frank about the limitations. The 13 studies disagreed with each other a lot, and the authors rated the certainty of the evidence as low. In most studies, the tear measurements in women with PCOS did not reach the TFOS DEWS II threshold for a dry eye disease diagnosis. Their conclusion was that women with PCOS "can experience mild dry eye symptoms", while tear volume and tear stability are similar.
Two individual studies explain why the picture is mixed. A 2023 study in International Ophthalmology found abnormal symptom scores in 54.7% of 53 women with PCOS, compared with 19.3% of 57 women without it. But a 2022 study of 66 women with PCOS, published in Photodiagnosis and Photodynamic Therapy, found no difference in symptom scores or tear break-up time. Treat any one study as a single data point, not the final answer.
Why might PCOS affect your tear film?
The most likely target is the oil layer of your tears, although nobody knows the full mechanism yet. Your tear film has three layers. A mucus layer sits directly on the eye, a watery layer sits on top of it, and a thin oil layer on the outside slows evaporation between blinks.
That oil comes from the meibomian glands, a row of tiny glands inside each eyelid. When they become blocked or shrink, the condition is called meibomian gland dysfunction, and tears evaporate too quickly. Eye doctors call this evaporative dry eye, and the PCOS research points here. The 2023 study found 40.21% gland loss in the upper lids of women with PCOS, compared with 15.76% in women without PCOS.
The androgen puzzle
Androgens are the male-type hormones, such as testosterone, that tend to run high in PCOS. A 2002 paper from David Sullivan's laboratory at Harvard showed that the meibomian gland is an androgen target organ. It carries androgen receptors. But there is a puzzle. In that research, too little androgen was the problem: androgen deficiency led to gland dysfunction and faster evaporation. In PCOS, androgens are usually high, not low.
So the simple story, "high testosterone dries your eyes", does not hold up. A 2017 study of 92 women with PCOS in Current Eye Research found no correlation between testosterone levels and any dry eye measurement. Your own androgen profile still matters, and our guide to androstenedione in PCOS explains why a testosterone test alone can miss it.
Inflammation, insulin and estrogen
Other hormones are involved too. The 2017 TFOS DEWS II report on sex, gender and hormones said that sex steroids explain much of why women develop dry eye more often than men. It named androgens and estrogens, as well as insulin and IGF-1. A 2022 study of 81 women with PCOS found that oil-gland loss increased alongside blood markers of inflammation, such as the neutrophil-to-lymphocyte ratio. If you have the inflammatory type of PMOS, that is the thread to watch. It is a correlation, not proof.
Do PCOS medicines make dry eye worse?
There is early, weak evidence that estrogen-progestogen hormone treatment could worsen dry eye measurements in some women with PCOS. A 2026 study in Seminars in Ophthalmology followed 60 women with PCOS and 30 women without it for 6 months. Half of the PCOS group took cyclic estrogen-progestogen hormones, the same two hormone types found in a combined pill. Over 6 months, their tear stability and oil-gland scores got worse. The other half took a different medicine, and their scores improved.
The authors warned that the groups were not randomized and differed at the start. So the results "should not be interpreted as causal drug effects". In plain words, do not stop your pill or hormone treatment because of this study.
Anti-androgen medicines are a fair question too. Sullivan's 2002 research linked anti-androgen treatment in men to oil-gland disease and shorter tear break-up time. We found no study of spironolactone and dry eye in women with PCOS. If your eyes got worse after starting a new medicine, tell the doctor who prescribed it. Bring the dates, because a new drug and new symptoms in the same month is useful information.
What tests does an eye doctor use for dry eye?
An optometrist or ophthalmologist can evaluate dry eye with a few quick, painless examinations. The 2017 TFOS DEWS II diagnostic report, written by an international panel with Wolffsohn as first author, sets out the order. It begins with a symptom questionnaire, then measures the stability and concentration of your tears, and finally stains the eye surface to identify damage.
| Test | What happens | What it tells you |
|---|---|---|
| OSDI or DEQ-5 | A short questionnaire about your symptoms | A score of 13 or more on the OSDI, or 6 or more on the DEQ-5, points to dry eye |
| Tear break-up time | After a blink, you keep your eyes open while the examiner counts the seconds until dry spots appear | The stability of your tear film. Under 10 seconds is a dry eye sign |
| Tear osmolarity | A tiny tear sample is collected | Whether your tears are too concentrated, or salty. TFOS DEWS II uses 308 mOsm/L or higher |
| Fluorescein and lissamine green stains | Dye drops, then an examination under a blue or white light | Dry or damaged patches on the eye surface |
| Meibography | An infrared photograph of the inside of your eyelid | Oil-gland loss, the most consistent PCOS finding |
| Schirmer test | Paper strips rest on your lower eyelid for 5 minutes | Your production of watery tears |
The oil-gland and tear-volume tests sort your dry eye into a type. Evaporative dry eye means the oil layer is deficient, while aqueous-deficient dry eye means you produce too little watery tear. The type matters. The 2017 DEWS II management report says it changes which treatment fits, and that many dry eye treatments still lack top-level trial evidence. Tell the eye doctor you have PCOS, and ask whether they evaluated your meibomian glands.
If you are still waiting on a firm PCOS diagnosis, our guide on how PMOS is diagnosed lists the tests on that side.
How to ease dry eyes with PCOS
The first steps for mild dry eye are simple, inexpensive and identical with or without PCOS. These come from the American Academy of Ophthalmology (AAO) and the National Eye Institute (NEI).
- Blink deliberately at screens. The AAO says people blink about 5 to 7 times a minute at a screen, against about 15 normally.
- Look up and away from your screen at regular intervals. Position the screen about 25 inches away, roughly an arm's length, so your gaze falls slightly downward.
- Use a warm compress. Hold a warm, damp washcloth over closed eyes for at least 1 minute, rewetting it to keep it warm. The AAO lists warm compresses among treatments that improve oil flow.
- Clean your lash line daily if it becomes crusty, using diluted baby shampoo on a cotton pad.
- Use artificial tears. If you use them more than 6 times a day, the AAO recommends preservative-free drops.
- Use a humidifier in dry rooms, and direct fans, heaters and car vents away from your face.
- Switch from contact lenses to glasses for a few days if your eyes are sore, and never sleep in lenses.
Give these steps a few weeks. If nothing changes, the next step is an eye exam, not a stronger drop from the pharmacy shelf. Prescription drops such as cyclosporine and lifitegrast exist, and the National Eye Institute lists both.
Does omega-3 or diet help PCOS dry eye?
Fish oil capsules did not beat a placebo for dry eye in the largest trial, and no study has tested diet for dry eye in PCOS. The DREAM trial, published in the New England Journal of Medicine in 2018, enrolled 535 people with moderate to severe dry eye. Participants took either 3,000 mg of fish oil (EPA and DHA) or olive oil every day for 12 months. Symptom scores fell by 13.9 points on fish oil and by 12.5 points on olive oil. That difference was not statistically significant. Tear tests did not differ either.
A 2019 Cochrane review of 34 trials and 4,314 people reached a softer verdict. Long-chain omega-3 supplements may give little to no symptom relief compared with placebo, and the reviewers called the evidence "uncertain and inconsistent".
So we will be candid: food is not a proven treatment for dry eye. The National Eye Institute does list low omega-3 or vitamin A intake as a risk factor. Eating oily fish such as salmon or sardines twice a week is a reasonable habit for other reasons. Just do not expect it to fix your eyes, and do not spend money on high-dose capsules for this alone.
Where food does help in PCOS is insulin and energy, which shape how you feel from day to day. PCOS Meal Planner builds your week around steadier insulin and adjusts as your weeks change, so it works as a system that adapts rather than a fixed plan. Start your plan here.
When should you see a doctor about dry eyes?
See an eye doctor if dry eye symptoms persist, get worse or interfere with daily life. That is the advice from the American Academy of Ophthalmology. Book an exam if the home steps above have not helped within a few weeks, or if you rely on drops many times a day.
Get seen the same day for sudden eye pain, a sudden change in vision, a very red eye or strong light sensitivity. Those signs are not typical of mild dry eye. The National Eye Institute notes that severe dry eye left untreated can damage the cornea, the clear front surface of the eye.
Also mention dry eyes to your primary doctor if you have a dry mouth or joint pain as well. Sjogren's syndrome, an autoimmune condition, causes both. It is a recognized cause of dry eye. For new PCOS treatments under study, see our roundup of the latest PCOS research and treatments.
Myths about PCOS and dry eye
Myth: PCOS gives everyone severe dry eye.
Reality: A 2026 review of 13 studies found mild symptoms. In most of those studies, women with PCOS did not meet the official criteria for dry eye disease.
Myth: High testosterone is what dries your eyes in PCOS.
Reality: Sullivan's 2002 lab work found that low androgen, not high, damages the eyelid oil glands. A 2017 study of 92 women with PCOS found no correlation between testosterone and dry eye measurements.
Myth: Fish oil fixes dry eye.
Reality: In the 2018 DREAM trial, 3,000 mg of fish oil daily for a year performed no better than an olive oil placebo.
Myth: Dry eye always means you are not producing enough tears.
Reality: In PCOS, tear volume on the Schirmer test usually looks normal. The difference appears in the oil layer, which prevents tears from evaporating.
Myth: Dry eye only affects women after menopause.
Reality: The PCOS eye studies examined women mostly in their 20s and 30s. One 2023 study had an average participant age of 25.
Frequently asked questions
Can PCOS cause dry eyes?
PCOS is linked to dry eye, but the link is usually mild. A 2026 review pooled 13 studies with 639 women with PCOS. Those women reported more symptoms, and their tears broke up faster on one test. Most did not have diagnosable dry eye disease. The 2026 review shows an association, but it does not prove that PCOS is the cause.
Why does PCOS cause dry eye?
No one knows yet. The most likely site is the meibomian glands, the oil glands in your eyelids that make the oil layer of your tears. Androgens act on these glands. In PCOS, the glands often look damaged, and one 2022 study linked this damage to blood markers of inflammation.
Is PMOS dry eye the same as PCOS dry eye?
Yes. PMOS, or Polyendocrine Metabolic Ovarian Syndrome, is the new name for PCOS, adopted in May 2026. The condition is the same. All the eye studies so far use the name PCOS, so their findings apply to PMOS as well.
How do hormones affect dry eye?
The oil glands and tear glands in your eyes respond to hormones. A 2017 expert report from TFOS DEWS II named androgens and estrogens, plus insulin. It said these hormones help explain why women get dry eye more often than men. In lab and clinic research, low androgen levels harm the oil glands.
Can birth control pills cause dry eyes with PCOS?
Possibly, but the evidence is limited. In one 2026 study, women with PCOS on estrogen-progestogen hormones had worse tear scores after 6 months. The groups were not randomized, so the hormones may not be the cause. Do not stop your pill on your own. Talk to your doctor first.
Do omega-3 supplements help dry eye?
Probably not much. In a 2018 trial of 535 people, fish oil worked no better than olive oil over 12 months. A 2019 Cochrane review of 34 trials found little to no symptom relief. Eat fish if you enjoy it, but do not buy high-dose capsules just for your eyes.
What is a normal tear break-up time?
The TFOS DEWS II rules treat under 10 seconds as a sign of dry eye. That cutoff applies with or without dye. In one 2023 study, women with PCOS averaged about 6 seconds on the test without dye. Women without PCOS averaged about 10. Ask your eye doctor for your own result.
What helps dry eyes with PCOS at home?
Blink on purpose at screens, and look away from the screen often. Hold a warm compress on closed eyes for at least 1 minute. Pick drops with no preservatives if you use drops often. Run a humidifier in dry rooms. If nothing helps within a few weeks, see an eye doctor.

How this article was made
We started from the 2026 meta-analysis in Current Eye Research and read every study we cite on PubMed in October 2026. The DREAM numbers, the DEWS II test order and the 2026 hormone study come from their published abstracts. Home-care recommendations come from the AAO and NEI patient information pages, read the same month.
Two limitations are worth naming. Every PCOS eye study we found was small, and most came from individual clinics. No trial has tested any diet for dry eye in women with PCOS, which is why this guide does not claim food will fix it.
The bottom line on PCOS dry eye: it is usually mild and mostly involves the oil layer. An eye examination with a tear break-up test will tell you more than any supplement.
This guide is general information, not medical advice. Eye symptoms need an eye exam to sort out. Do not stop a prescribed medicine without talking to the doctor who prescribed it.
