Dry eye is more than just an annoyance - it’s a widespread condition that leaves millions feeling like sandpaper's stuck in their eyes. But what causes it, who's most likely to deal with this gritty reality and is there a solution to help relieve the pain? Let's dive into it.
The Causes: Why Your Eyes Dry Out
Dry eye happens when your tears can’t keep your eyes lubricated, either because you’re not making enough or they evaporate too fast. Studies pinpoint two main types: aqueous-deficient dry eye (not enough tears) and evaporative dry eye (tears vanish too quickly). A 2017 report from the Tear Film and Ocular Surface Society (TFOS) Dry Eye Workshop II explains it’s a “multifactorial disease” driven by tear film instability, inflammation, and even nerve issues.
One big culprit? Aging. Research from the Women’s Health Study and Physician’s Health Studies shows tear production drops as we get older, especially after 50. Hormonal shifts—like those during menopause—can make it worse by reducing tear output.
Another trigger is meibomian gland dysfunction (MGD), where the oily layer of tears gets clogged, leading to rapid evaporation. A 2023 study in the Indian Journal of Ophthalmology notes MGD is a leading cause of evaporative dry eye.
External factors play a huge role too. Staring at screens for hours cuts blinking rates, drying out eyes—a 2016 study in BMC Ophthalmology linked this to rising dry eye in younger folks, including kids hooked on smartphones.
Environmental stressors like dry air, wind, or pollution irritate the ocular surface, while medications (think antihistamines or antidepressants) can dial down tear production, per a 2015 Deutsches Ärzteblatt International review.
Medical conditions also stack the deck. Sjögren’s syndrome, an autoimmune disease, attacks tear glands, affecting about 10% of aqueous-deficient cases, says Cleveland Clinic research. Diabetes doubles your risk—half of patients develop dry eye due to nerve damage or blood vessel changes, according to a 2007 study in Ophthalmology.
Who Suffers Most?
So, who’s hit hardest? Women top the list. The Beaver Dam Eye Study found dry eye is 50% more common in women than men, thanks to hormonal fluctuations from pregnancy, birth control, or menopause. Age amplifies this—prevalence jumps every five years after 50, per the Women’s Health Study. Older women, especially post-menopause, often face the worst of it.
Geographically, Asia sees higher rates than North America or Europe, possibly due to climate or lifestyle, notes a 2022 Cleveland Clinic overview. Contact lens wearers are also at risk—up to 30% ditch lenses due to dryness, per Ophthalmology Times (2019). And don’t forget students or office workers glued to screens—a 2022 Journal of Ophthalmic and Vision Research study found 22% of Iranian university students had dry eye, tied to computer use.
Solutions and Treatments: Relief for Dry Eyes
Dry eye doesn’t have to be a life sentence—treatments range from simple fixes to advanced therapies, backed by science. Stiltec offers a new & different approach to treating dry eye symptoms, through vitamin supplementation. Lacritec delivers a proprietary blend of omega fatty acids sourced from Flax Seed, Fish Oil & Borage Oil. This helps to reduce lacrimal gland inflammation, resulting in improved tear production, tear film break up time & reduced tear film surface tension. You can find more information here.
For mild cases, artificial tears are a go-to. A 2020 Clinical Ophthalmology study found over-the-counter drops with hyaluronic acid improve tear film stability, easing symptoms fast. Look for preservative-free options to avoid irritation with frequent use.
Lifestyle tweaks help too. The American Academy of Ophthalmology suggests the 20-20-20 rule—every 20 minutes, look 20 feet away for 20 seconds—to boost blinking and combat screen-induced dryness. Humidifiers tackle dry air, while wraparound sunglasses shield eyes from wind, per a 2018 Eye journal review.
For evaporative dry eye tied to meibomian gland dysfunction (MGD), warm compresses and lid massages unclog glands. A 2021 British Journal of Ophthalmology study showed consistent heat therapy boosts oil flow, stabilizing tears.
The Bottom Line
Dry eye stems from aging, hormones, screen time, environment, meds, and health conditions like Sjögren’s or diabetes. Women, older adults, Asians, and screen junkies suffer most. Research keeps uncovering why—like inflammation’s role or microbiome shifts (see 2022 International Ophthalmology)—but for now, knowing the causes can help you spot the signs early. Got gritty eyes? You’re not alone, and science has your back.
