You blink. It doesn't help. Your eyes still feel like someone's rubbed sand into them, or they're burning after an hour on your phone, or they're so itchy you've caught yourself rubbing them in the middle of a meeting. Sound familiar?
If so, you're dealing with one of the most common things we see at the clinic - dry eye. And despite how uncomfortable it is, most people wait months before actually getting it checked, usually because they assume it'll just go away on its own. Sometimes it does. Often, it doesn't, because the cause is still there, quietly doing its thing every day.
Here's what's usually behind it.
What's Actually Happening When Your Eyes Feel Dry?
Every time you blink, your eyes get coated in a thin film made of water, oil, and mucus. It sounds unglamorous, but that film is doing a lot of work - keeping your eyes smooth, clear, and protected. When something throws that off, whether you're not producing enough tears or they're evaporating too fast, you get dryness. And the symptoms aren't always what you'd expect. Burning, itching, redness, blurry vision that clears when you blink - even watery eyes, oddly enough, since irritated eyes sometimes overproduce tears to compensate.
With that out of the way, here's what tends to cause it.
1. Too Much Screen Time
This one's almost unavoidable now. When you're focused on a screen, your blink rate drops - by a lot, sometimes more than half. Fewer blinks means your tear film isn't getting refreshed the way it should, and by the afternoon, your eyes are paying for it. If you work on a laptop for eight-plus hours, this is probably at least part of your problem.
2. Environmental Factors
Dry climates, strong wind, dust, smoke, even air conditioning - all of it pulls moisture away from your eyes faster than they can keep up. If you've noticed your eyes feel worse in one particular room, or during certain months, this is usually why.
3. Aging
Tear production slows down with age, especially past 50. It's one of the most consistent patterns we see, and it affects nearly everyone eventually, though some people notice it earlier than others.
4. Hormonal Changes
This one catches a lot of women off guard. Pregnancy, menopause, and birth control can all affect the glands responsible for tear production, and dry eyes often show up - or get worse - right alongside those changes.
5. Certain Medications
Antihistamines, antidepressants, blood pressure medication, decongestants, even certain acne treatments - all of these can dry your eyes out as a side effect. If your symptoms started around the same time as a new prescription, that's not a coincidence worth ignoring.
6. Your contact lenses
Lenses sit right on the surface of your eye, and depending on the material, how long you wear them, or how well they fit, they can interfere with your natural tear film. A lot of contact lens wearers tell us their eyes feel fine in the morning and rough by evening - that's this.
7. Meibomian Gland Dysfunction (MGD)
This one's less talked about, but it's actually one of the most common causes we diagnose. Tiny glands along your eyelids produce the oil layer that keeps your tears from evaporating too fast. When those glands get blocked, your tears disappear quicker than they should, even if you're producing enough of them. You generally can't catch this without an actual eye exam, which is part of why it goes undiagnosed so often.
8. Allergies
Itchy, red, watery eyes from pollen, dust, or pet dander can look almost identical to dry eyes - and sometimes both are happening at once, which makes things feel worse than either alone.
9. Autoimmune Conditions
Less common, but worth mentioning: conditions like Sjögren's syndrome, rheumatoid arthritis, and lupus can affect the glands that produce tears. If your dryness is severe, comes with a dry mouth too, or just isn't responding to normal treatment, this is something your doctor should rule out.
10. Post-Surgical Dryness
If you've had LASIK or cataract surgery recently, some dryness afterward is completely normal and usually temporary - it happens because surgery can briefly affect the nerves that trigger tear production. Anyone who's had cataract surgery in Siliguri recently and is dealing with this should mention it at their follow-up rather than just toughing it out.
When Should You See an Ophthalmologist?
Mild dryness from a long day at your desk isn't usually a big deal. But if it's been going on for more than a few days, affecting your vision, causing real pain or sensitivity to light, or just not responding to eye drops - it's worth getting an eye doctor in Siliguri to take a proper look. Left alone long enough, chronic dry eye can actually damage the surface of your eye, which is obviously easier to prevent than to fix.
Simple Eye Care Tips to Manage Dry Eyes
- Use preservative-free artificial tears regularly, not just when it's bad
- Keep a humidifier running if your space is dry
- Actually drink enough water during the day
- Make a conscious effort to blink more during screen time
- Don't sit directly in front of AC vents
- Take eye makeup off properly before bed
- Don't skip regular eye exams just because nothing feels wrong
Frequently Asked Questions (FAQs)
What causes dry eyes suddenly?
Usually a jump in screen time, dry weather, a new medication, or seasonal allergies. If it's sudden and severe, get it checked rather than waiting it out.
Can dry eyes be cured permanently?
Depends on the cause. Lifestyle-driven dry eye often clears up well with the right habits. Chronic conditions usually need ongoing management rather than a single fix.
Is dry eye syndrome serious?
Mild cases, not really. Left untreated for a long time, it can damage the eye's surface, so it's worth addressing early rather than ignoring it.
Conclusion
Dry, burning, itchy eyes aren't something you just have to live with, even though it's tempting to brush it off. The real fix depends on figuring out what's actually causing it, which is different for everyone.
At The Himalayan Eye Institute, we see this constantly, and we'd rather find the actual cause than hand you a bottle of drops and send you on your way. If this has been bothering you for a while, it's worth getting it looked at properly.
