Dry eyes are one of the most common eye complaints, and the fix depends on what’s causing them. For mild cases, over-the-counter lubricating drops and a few habit changes often bring relief within days. For persistent dryness, the problem usually traces back to either your eyes not producing enough tears or your tears evaporating too quickly, and each type calls for a different approach.
Start With Artificial Tears
Lubricating eye drops (called artificial tears) are the first thing to try. They’re available without a prescription and work by temporarily restoring moisture to the eye’s surface. If you’re using them a few times a week for occasional dryness, standard bottles with preservatives are fine. But if you need drops more than four times a day, or your dryness is moderate to severe, switch to preservative-free versions. The preservatives in multi-dose bottles can irritate already-sensitive eyes and make things worse over time. Preservative-free drops typically come in single-use vials.
Give a particular brand a week or two before deciding it isn’t working. Artificial tears vary in thickness: thinner drops feel more natural but don’t last as long, while gel-based drops stay on the eye longer but can temporarily blur your vision. Many people keep a thinner drop for daytime and a thicker gel for bedtime.
Adjust Your Environment
Your surroundings play a bigger role in eye moisture than most people realize. Indoor humidity levels of about 45% or higher are best for your eyes. In winter, heated indoor air can drop well below that. A humidifier in your bedroom or workspace makes a noticeable difference. Avoid sitting directly in the path of fans, air vents, or space heaters, all of which accelerate tear evaporation.
If you wear contact lenses, they’re a common aggravator. Consider switching to glasses on days when dryness is worst, or talk to your eye care provider about lenses designed for dry eyes.
Reduce Screen-Related Dryness
People blink about 66% less often when staring at a screen, which means your tear film breaks down faster during long stretches of computer or phone use. The simplest countermeasure is the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This gives your eyes a chance to blink fully and re-spread your tear film. It sounds almost too simple, but it’s one of the most consistently recommended strategies by eye care professionals.
Positioning your monitor slightly below eye level also helps. When you look up or straight ahead, more of your eye surface is exposed to air. Looking slightly downward narrows that exposed area and slows evaporation.
Try Warm Compresses
The most common form of dry eye is evaporative, meaning your tears disappear too quickly because the oily outer layer of your tear film is deficient. That oil comes from tiny glands along your eyelid margins called meibomian glands. When those glands get clogged, the oil can’t do its job.
A warm compress helps soften and release those blocked oils. Soak a clean washcloth in warm (not hot) water, test it on the inside of your forearm to make sure it’s comfortable, then lay it over your closed eyes for about 10 minutes. Do this once or twice daily. After removing the compress, gently massage your eyelids in small circular motions to help express the oils. Consistency matters here: a single session won’t transform your symptoms, but doing this daily for a few weeks often produces real improvement.
Consider Omega-3 Fatty Acids
Omega-3s, the fats found in fatty fish, flaxseed, and walnuts, support the oily layer of the tear film. A combined daily intake of at least 500 mg of EPA and DHA (the two key omega-3 types) is the general recommendation from lipid researchers. You can get this from two servings of fatty fish per week or from a fish oil supplement. One clinical study found that participants taking 600 mg of EPA and DHA daily saw measurable improvements in tear stability over a short treatment period.
Omega-3s won’t replace eye drops for immediate relief, but they address one of the underlying contributors to evaporative dry eye over weeks to months.
Why Dry Eyes Happen
Dry eye has two main forms. The more common type, evaporative dry eye, stems from problems with the oil-producing glands in your eyelids. Without enough oil on the tear surface, tears evaporate too fast. Chronic inflammation of the lids can damage these glands further, creating a cycle that worsens over time if left untreated.
The less common type involves your tear glands simply not producing enough of the watery component of tears. This form sometimes signals an underlying autoimmune condition, which can gradually damage the tear-producing glands. Many people have a mix of both types. Risk factors include aging (especially in women after menopause), certain medications like antihistamines and antidepressants, and autoimmune conditions.
When Drops Aren’t Enough
If you’ve tried artificial tears, warm compresses, and environmental changes for several weeks without adequate relief, prescription options exist. Anti-inflammatory eye drops containing immune-suppressing compounds can reduce the surface inflammation that perpetuates dry eye. These aren’t fast-acting like artificial tears; they typically take several weeks to reach full effect, and your eye doctor will monitor you during that period.
For people whose tears drain away too quickly, tiny devices called punctal plugs can be placed in the tear ducts. Each plug is about the size of a grain of rice and blocks the drainage channel that normally carries tears away from the eye surface. The procedure is quick, done in-office, and reversible. Plugs are generally considered when artificial tears alone haven’t provided enough relief.
Signs Your Dry Eyes Need Professional Attention
Occasional dryness after a long flight or a day in air conditioning is normal. But if you’re dealing with persistently red, irritated, tired, or painful eyes that don’t respond to over-the-counter drops and basic habit changes, it’s worth getting evaluated. An eye care provider can determine whether your issue is with tear production, tear evaporation, or both, and can check for underlying conditions driving the problem. Changes in vision alongside dryness, or eye pain that goes beyond mild irritation, should prompt a visit sooner rather than later.
