Dry eye has several possible causes; persistent symptoms deserve an assessment, especially with pain or vision change.
Why dry eye can feel confusing
Dry eye develops when there are too few tears or when tears do not work well enough to keep the eye surface comfortable. It can cause burning, grittiness, redness, light sensitivity, and fluctuating blur. Some people also notice watering as the eye reacts to irritation.
Screen concentration can reduce blinking. Wind, dry air, contact lenses, some medicines, and other conditions may contribute too. A single symptom cannot tell you which factor is responsible.
What to try and when to ask
Take screen breaks, blink fully, limit direct air flow, and consider a humidifier. Over-the-counter artificial tears may help mild cases, but ask an eye-care professional which product fits your situation. Do not continue self-treating persistent pain, significant redness, light sensitivity, or worsening vision.
Common questions
Why do dry eyes sometimes water?
Watering can be a response to an irritated eye surface. The extra tears may not have the balance needed to keep the surface comfortable. An examination can help distinguish dry eye from allergy, infection, or another reason for watering.
Are all artificial tears the same?
Products differ in ingredients and intended use. Mild dryness may improve with an over-the-counter lubricant, but frequent use or ongoing symptoms are reasons to ask an eye-care professional for a specific recommendation. Avoid using redness-relief drops as a substitute for diagnosis.
For persistent changes or symptoms, arrange an eye examination. Seek urgent medical care for sudden vision loss, a new curtain or shadow, many new floaters with flashes, severe eye pain, an eye injury, or sudden double vision.
