Dry eye rarely announces itself as dryness. It turns up as grit, burning, tired eyes by mid-afternoon, vision that smears between blinks, or eyes that stream in the wind. The pattern of symptoms is genuinely informative — it points towards which part of the tear film is failing.
Grittiness, as though there is sand under the lid. Burning or stinging that builds through the day. Redness along the lid margin. Heavy, tired eyes that give out in the evening or after screen work. Vision that blurs and then clears when you blink — the tear film breaking up and being restored. Contact lenses that used to be comfortable all day and now are not. And, confusingly, watering: eyes that stream constantly are usually dry eyes producing emergency reflex tears, not eyes with too many tears.
Symptoms worst on waking suggest the eyes are drying overnight — incomplete lid closure, or a night-time surface problem. Symptoms that build through the day point to evaporation and gland dysfunction. Wind, air conditioning, car heaters, aircraft cabins and long screen sessions all make evaporative dry eye worse, because each of them either strips the tear film or suppresses your blink rate. Itch, rather than burn, points more towards allergy or Demodex than dry eye alone. These distinctions change the treatment, which is why we ask about them in detail.
One of the more counter-intuitive findings in dry eye medicine is that symptoms and clinical signs correlate poorly. Some people have badly damaged glands and few complaints, because chronic disease has dulled corneal nerve sensitivity. Others describe severe discomfort with a surface that looks close to normal, and their problem is often neuropathic rather than a tear-volume one. Both are real, and both are missed by an assessment that only asks how the eyes feel. Measuring the tear film is what separates them.
Book an assessment if symptoms have persisted beyond a few weeks; if lubricant drops help for only minutes; if vision fluctuates through the day; if contact lens wear has become uncomfortable; or if your eyes water constantly. Seek same-day medical care instead for sudden vision loss, significant eye pain, light sensitivity with a red eye, or discharge — those are not dry eye and need urgent assessment. Everything else is worth measuring properly, because dry eye is progressive when the underlying gland disease is left alone.
