Perimenopause and Eye Health: Dry Eyes, Vision Changes, and What to Do
Perimenopause can cause dry eyes, blurred vision, and prescription changes. Learn what drives these symptoms, evidence-based treatments, and when to see a specialist.
How Estrogen Affects the Eyes
Sex hormone receptors, including estrogen and androgen receptors, are found in the lacrimal (tear) glands, meibomian glands, corneal cells, and conjunctiva. Estrogen influences the production and composition of the tear film, which is the thin three-layer coating that keeps the eye surface moist, clear, and protected. The tear film has an outer lipid layer (produced by meibomian glands in the eyelids), a middle aqueous layer (produced by the lacrimal gland), and an inner mucin layer. When estrogen and androgen levels decline in perimenopause, both the aqueous and lipid components of the tear film can be affected, leading to dry eye syndrome. Androgens in particular play a major role in meibomian gland function; declining androgen levels affect lipid production, which causes the tear film to evaporate more quickly. The result is eyes that feel gritty, sore, tired, or intermittently blurry.
Dry Eye Syndrome: Symptoms and Patterns
Dry eye syndrome is one of the most common eye complaints in perimenopausal and postmenopausal women. Symptoms include a persistent gritty or sandy sensation, burning, redness, sensitivity to wind and smoke, intermittent blurred vision that clears with blinking, and paradoxically, excessive watering (the eyes produce reflex tears in response to surface irritation). Symptoms tend to worsen in dry environments (air-conditioned offices, aeroplanes), during prolonged screen use, in cold wind, and at the end of the day. Perimenopause-related dry eye often develops gradually and is sometimes initially dismissed as tiredness or strain. If eye drops alone do not provide sustained relief, or if symptoms are affecting work or quality of life, a formal assessment is worthwhile.
Contact Lenses and Perimenopause
Contact lens wearers often notice perimenopause affecting their lens comfort before anything else. A lens that previously felt comfortable all day may now cause discomfort by midday, produce redness, or feel like it is drying out on the eye. This is because contact lenses disrupt the precorneal tear film and demand a healthy and stable tear production to remain comfortable. When tear volume and quality decline, lens tolerance decreases. Some women find they can switch to daily disposable lenses (which accumulate less protein and lipid deposits), use lubricating drops compatible with contact lenses, or reduce wearing hours and manage on glasses for part of the day. If symptoms are severe or progress to persistent eye redness and discomfort even without lenses, seeing an optometrist or ophthalmologist for a meibomian gland assessment is the appropriate next step.
Prescription and Vision Changes
Fluctuating estrogen levels can directly affect the cornea's shape and hydration, which changes how light is refracted. Some women notice their vision prescription shifting during perimenopause, particularly experiencing difficulty with near vision that is more variable than expected. This can be confusing if a new pair of glasses or updated contact lens prescription feels accurate one week and not the next. Presbyopia (age-related difficulty with near vision) also begins in this life stage, typically from the mid-40s, as the lens of the eye becomes less flexible. The two effects can overlap, making it harder to understand why glasses are suddenly not working well. Informing your optometrist that you are in perimenopause is useful clinical context. They can factor hormonal fluctuation into their assessment and may recommend rechecking your prescription at different points in your cycle or across a few months rather than prescribing based on a single visit.
Omega-3 Fatty Acids and Dry Eyes
Omega-3 fatty acids have a specific mechanistic rationale for dry eye treatment: they support meibomian gland function and help maintain the lipid layer of the tear film. Several clinical trials have tested oral omega-3 supplementation for dry eye with mixed but generally positive results, particularly for meibomian gland dysfunction. A large 2018 JAMA trial found no significant benefit over placebo for omega-3 supplements in diagnosed dry eye disease, but this study has been criticised for using a refined olive oil placebo with some omega-9 activity. Smaller, better-designed trials and meta-analyses generally support a modest beneficial effect of EPA and DHA supplementation on dry eye symptoms. Eating oily fish two to three times per week provides EPA and DHA naturally. If supplementing, look for products providing at least 1,000 mg combined EPA and DHA per day from triglyceride-form fish oil, which is better absorbed than ethyl ester forms.
Screen Time Management and Practical Relief
Screen use significantly worsens dry eye because people blink less frequently when concentrating on a screen, reducing the regular distribution of tears across the eye surface. The 20-20-20 rule is a practical guideline: every 20 minutes, look at something 20 feet away for 20 seconds. This provides a pause in focused near work and prompts a complete blink cycle. Increasing ambient humidity in your working environment with a desk humidifier can help if you work in a dry office or heated indoor space in winter. Preservative-free lubricating eye drops are suitable for frequent use throughout the day and do not carry the rebound effects that some medicated drops can produce. Warm compresses applied to closed eyelids for 5 to 10 minutes once or twice a day can liquefy hardened meibomian gland secretions and improve lipid layer stability, particularly helpful for those with meibomian gland dysfunction.
When to See an Ophthalmologist
Many dry eye symptoms can be managed in consultation with an optometrist. An ophthalmologist is needed if symptoms are severe and not responding to standard measures, if there is any concern about other eye conditions (glaucoma, macular changes, cataract), or if you experience sudden vision changes, flashes, floaters, or any loss of visual field. These latter symptoms require urgent rather than routine assessment. Women with diabetes, autoimmune conditions such as Sjogren's syndrome (which causes profound dry eye), or rheumatoid arthritis should have regular ophthalmological monitoring regardless of perimenopause. If you use HRT and notice changes in your dry eye symptoms, in either direction, let your prescriber know. Some women report improved dry eye on HRT, though the evidence for systemic HRT as a treatment for dry eye is inconsistent. Local treatments remain the primary approach.
