What Are the Symptoms of Dry Eye? Grit, Burning, Even Tears

Your eyes sting by evening and water in the wind; what are the symptoms of dry eye, and can watering really be one of them? Yes, it can. The usual signs are a gritty, sandy feeling, stinging or burning, redness, sensitivity to light and blur that clears when you blink, and watery eyes belong on that list because a dry surface sets off reflex tears.

Sharp pain, a sudden drop in vision, or one very red, light-sensitive eye are not typical of dry eye and need an eye doctor the same day.

Hello, I'm Dr. Kim Sun-young, Medical Director at Healing Eye Clinic in Gangnam, Seoul. The surface of the eye is home ground for me: I trained in ophthalmology at the Catholic Medical Center and served as a clinical professor of cornea and cataract at Uijeongbu St. Mary's Hospital. Our Dry-Eye Clinic looks for the root cause before adding more drops, with programs such as IPL and meibomian-gland care, and a medical interpreter for your language joins the consultation at no extra charge.

We're registered with Korea's Ministry of Health and Welfare for international patients.

If you're coming to Seoul anyway, send a short list of your symptoms, the time of day they're worst, and the names of any eye drops and daily medicines you take on WhatsApp, and ask whether a dry-eye exam would fit into your dates. The consultation is free.

Why would a dry eye water?

The tear film has three layers: a thin layer of oil on top, a watery middle, and a mucus layer that holds everything to the eye. The US National Eye Institute describes three ways it fails: the glands don't make enough tears, the tears dry up too quickly, or the tears don't work well enough to keep the eye wet.

When the oil layer is thin, the water underneath evaporates within seconds of each blink. The surface dries in patches, the nerves complain, and the tear gland floods the eye with emergency tears. Those reflex tears are mostly water. They run off the eye and dry just as fast, so you can be dabbing your cheeks and still feel sand under the lid.

That's why the amount of tears says less than the timing. Eyes that feel fine in the morning and burn by late afternoon tell a different story from eyes that are sore the moment you wake up.

What each symptom often points to

Most people have more than one of these, and the patterns overlap. Read the table as a way to describe your eyes to a doctor, not as a diagnosis.

Risks and side effects to know

The lid row matters more than people expect. Among the dry eyes I examine, red, inflamed lid margins and glands that release thick, yellowish oil when pressed are common, and in those eyes lid cleaning alone treats much of the problem.

Are you more likely to have it?

The National Eye Institute lists being 50 or older, being female, wearing contact lenses, not getting enough vitamin A or omega-3 fatty acids, and autoimmune conditions such as lupus or Sjögren syndrome as risk factors. Everyday life adds more: an air conditioner or heater blowing at your face, allergy medicines that dry the eyes the way they dry the nose, and short sleep. In women, tears tend to fall as hormones decline after menopause.

Say you're 54, a few years past menopause, in reading glasses, and you're visiting Seoul for a holiday. Your eyes are comfortable at breakfast, burn by four o'clock at the laptop, and stream on windy walks. That pattern points first at evaporation, the oil layer. I'd want to look at your lid margins and how your oil glands empty before anything else, because if the glands are blocked, more drops only rinse the surface.

If habits and lid care aren't enough, and sleep or hormones can't be changed, I don't wait for those to be solved. Treatments that keep tears on the eye longer are the faster route: punctal plugs, tiny plugs in the tear drains, or autologous serum drops made from your own blood. Our English home page lists the clinic hours; Friday runs late until 21:00 and Saturday until 14:00, which helps if you only have an evening or a weekend morning free.

If you'd like to know how that first conversation goes, I've written about what happens in a free consultation.

If you're also considering vision correction, dry eye changes the plan, and severe dry eye is often treated first. LASIK and dry eye risk covers that decision in detail.

Habits worth changing before any treatment

Artificial tears relieve dryness for roughly half an hour. They don't fix why the eye is drying, so it helps to change the habits that keep drying it.

Blink fully. When you concentrate on a screen you blink far less, and many people with dry eye only half close their lids. A complete blink spreads fresh tears and squeezes oil out of the glands along the lid edge. Practise it: close until you feel the lids touch, squeeze gently, then open.

Move the air. Turn air-conditioning and heater vents away from your face, run a humidifier in dry months, and on a long flight point the overhead nozzle away from you. Wear goggles on a bike or scooter.

Clean your lids. Lashes need washing just like your hair. If the lid edges are already red and inflamed, use a dedicated eyelid cleanser with tea tree oil and clean gently, the way you'd remove makeup.

Sleep, and check how you sleep. Short sleep sharply cuts tear production, and some people sleep with their lids slightly open without knowing it. Ask someone at home to look, or take a photo.

When the blur doesn't clear with a blink

Dry-eye blur comes and goes, and a blink clears it for a moment. Blur that stays, glare and halos around headlights that have built up over months, or colours that look faded are more typical of an early cataract, and after 50 the two often overlap. My post on early cataract symptoms walks through those signs.

If you're planning any eye surgery, there's a second reason to treat dry eye first. An unstable tear film can distort the corneal measurements surgeons use to plan laser vision correction or choose a cataract lens, so a calmer surface before the exam generally gives more reliable numbers.

Which symptoms mean you shouldn't wait?

Most dry eye flares and settles with the weather, flights, screen-heavy weeks and short nights. That ups and downs pattern is normal for the condition, and people differ a lot in how much habits alone can do, so the treatment that helps one person may not be enough for another.

Some people should get checked sooner rather than later: contact lens wearers with a red, painful eye, since infection is possible; anyone with Sjögren syndrome or another autoimmune condition; and anyone recovering from laser eye surgery, where aftercare at home after laser eye surgery explains what's expected. The National Eye Institute also advises telling your doctor when dry eye gets in the way of daily life, and notes that severe dry eye left untreated can damage the cornea.

See an eye doctor the same day for pain rather than discomfort, a sudden drop in vision, one very red eye that hates light, or thick discharge. Those aren't typical dry eye.

Once you're home, dry eye is usually something you manage rather than finish. Our dry-eye programs such as IPL and gland care list no downtime, so ask on WhatsApp how many sessions your program would involve and whether they fit one stay. Keep a copy of your exam results so an eye doctor near you can take over routine follow-up. If a flare doesn't settle, send a daylight photo of your eyes and a list of what you've been using on WhatsApp.

The original Korean dry-eye clinic page on our head site describes the same programs, if your doctor at home would like to see it.

A small first step

If your eyes match more than two lines of that table, keep a three-day note of when they're worst and what you tried, take one photo of your eyes in daylight, and send both on WhatsApp with your Seoul dates. The consultation is free. When you come, what I look at under the microscope is your lid margins and how much oil the glands release, because that tells us whether gland care or more tears on the eye is the right place to start.
