Other Causes of Dry Eye Symptoms: Allergies, Blepharitis, and More

Many people describe dry eye as a sandy or scratchy sensation, as if something is caught in the eye. This happens when the eyes do not produce enough tears or when tears evaporate too quickly, leaving the eye surface unprotected. Over-the-counter artificial tears and making a conscious effort to blink regularly can help ease this feeling between visits.

Itching and redness are signs that the surface of the eye is irritated and inflamed. Rubbing your eyes may feel like it helps, but it often makes the irritation worse. A clean, cool compress applied gently over closed eyes can reduce inflammation and provide temporary comfort.

Dry eyes can cause blurred vision that comes and goes, particularly after extended screen use or reading. Some people also develop photophobia, which is an increased sensitivity to bright light. Taking regular breaks from screens and wearing UV-protective sunglasses outdoors can help reduce both of these symptoms.

It may seem counterintuitive, but dry eyes often cause the eyes to water excessively. This happens because the eye senses irritation and triggers a reflex to produce more tears, but these reflex tears are lower quality and do not coat the eye effectively. If watery eyes are a persistent problem, an eye care provider can help identify whether dryness is the root cause.

Yes, and this is one of the most confusing aspects of the condition. Reflex tearing, the kind triggered by irritation, produces a different type of tear than the steady, protective layer your eyes need. These reflex tears flush the eye but do not coat it properly, so the underlying dryness remains. This is why treatment focuses on improving the tear film rather than simply reducing watering.

No, you should never stop a prescribed medication without speaking to your prescribing provider first. Instead, mention your dry eye symptoms at your next appointment so that alternatives, dose adjustments, or supportive eye care strategies can be explored together. In many cases, using lubricating eye drops alongside the medication provides enough relief to continue treatment comfortably.

Over-the-counter artificial tears add moisture to the eye surface temporarily. Prescription drops such as cyclosporine and lifitegrast work differently by targeting inflammation on the eye surface itself, which helps the eye's own glands produce better-quality natural tears over time. They typically take several weeks to show full benefit and are usually recommended for moderate to severe cases that do not respond to lubricating drops alone.

Punctal plugs are tiny, biocompatible implants placed into the small drainage openings at the inner corners of the eyelids. By slowing the rate at which tears drain away, they help keep more moisture on the eye surface throughout the day. A provider may suggest them when lubricating drops alone are not providing adequate or consistent relief, and the procedure is typically quick and well tolerated.

If your symptoms persist for more than a week despite using artificial tears and making lifestyle adjustments, or if you experience significant pain, sudden vision changes, or symptoms that interfere with daily activities, it is time to schedule an eye exam. Some underlying causes of dry eye, such as autoimmune conditions or chronic blepharitis, require professional treatment that home remedies cannot address on their own. Early care leads to better outcomes and prevents the condition from becoming more difficult to manage.

Nutrition can influence tear quality, particularly through omega-3 fatty acids found in foods like salmon, sardines, walnuts, and flaxseeds. These healthy fats help support the oil layer of the tear film, which slows evaporation. While diet alone is rarely a complete solution for dry eye, combining a balanced diet with other treatments often improves overall comfort.
