How to Track Dry Eyes and Find What Sets Them Off
Dry eye is easy to underplay in an appointment. By the time you sit down, your eyes may have settled, and it is hard to recall how bad last Tuesday afternoon was. Yet dry eye disease is defined by how it behaves over time: how often it interferes, what provokes it, whether treatments help. A simple daily record fills that gap. It shows how many days a week your eyes stop you reading or working comfortably, which conditions or medications came before bad spells, and whether the trend is stable, improving or worsening.
What to log each day
Rate your eyes once or twice a day, or whenever they bother you, as mild, moderate or severe, and keep the scale consistent. Note the time of day the symptoms peak: on waking (often a sign of incomplete lid closure or night-time evaporation), late afternoon after screen work, or in particular rooms. Describe the quality in a few words: gritty, burning, stinging, tired, watering, light sensitive, or blurring that clears when you blink. Record practical markers that show impact rather than adjectives: how many times you used artificial tears, how many hours your contact lenses were comfortable, whether you had to stop reading or driving. Note eyelid redness or crusting, and any warm compresses or lid cleaning you did, since meibomian gland care is a common treatment and its effect takes weeks to show.
Triggers and patterns worth charting
Log screen time, sleep, allergens, travel, cold or windy weather and your daily medications on the same timeline as your eye symptoms, then look back after three or four weeks. Screen-related dryness typically builds through the day and fades on weekends. Dryness that worsens in winter often follows indoor heating and cold wind. Flights and long drives with the air vents on show up as clear spikes. Short or poor sleep is commonly followed by grittier mornings. New medications, including over-the-counter antihistamines, sleep aids and decongestants, deserve their own entry with a start date. If your eyes are bad every day regardless of screens, weather or sleep, especially alongside a dry mouth, joint pain or fatigue, that pattern is itself the finding to take to a doctor.
When to seek medical advice
Get same-day eye care for severe or sudden eye pain, a red and painful eye in a contact lens wearer, strong light sensitivity, discharge, a visible white spot on the cornea, or vision that stays blurred after blinking, since a damaged corneal surface can become infected. Book a routine appointment with an optometrist or ophthalmologist if dryness lasts more than a few weeks despite breaks, humidity and lubricating drops, if you need drops very often, if lenses become intolerable, or if your eyelids are persistently inflamed. Mention dry eyes to your doctor if they come with a dry mouth, swollen salivary glands, joint pain or stiffness, rashes, fatigue or Raynaud's, as autoimmune conditions such as Sjögren's, rheumatoid arthritis and lupus can cause dryness and benefit from early recognition.
How Trace Health supports the record
Logging takes one tap, so a burning spell at the end of a workday is captured in a second instead of forgotten by bedtime. Mild, moderate and severe keep the record simple and consistent over months, and a note on any entry holds the details: drops used, lens hours, where you were. Screen time, sleep, allergens, travel, weather and medications sit on the same timeline, where you can see which of them line up with your worse days. Dry mouth, eye pain or redness and vision changes can be tracked alongside to show the full picture. The doctor-ready PDF condenses weeks or months into a few pages for an eye, dental or rheumatology appointment. Data stays on your iPhone by default, with optional private iCloud sync, and no account is required.
Frequently Asked Questions
How do I know if my dry eyes come from screens or something else?
Compare workdays with days away from screens. Screen-related dryness builds through the afternoon, improves overnight, and largely settles on a weekend or holiday. Dryness from reduced tear production or eyelid gland problems tends to be present on waking, barely changes with a lighter screen day, and may come with crusted or red lid margins. Logging screen hours next to eye severity for three or four weeks makes the difference visible. If severity stays high on low screen days, or a dry mouth appears too, take the chart to an eye doctor rather than simply adding more drops.
How can I tell whether a treatment is working?
Write down the start date of every treatment: preservative-free drops, gels at night, warm compresses and lid hygiene, omega-3, prescription anti-inflammatory drops, punctal plugs, or a change in contact lenses. Most need weeks, not days, to show an effect; lid treatments for meibomian gland dysfunction can take a month or more. Keep rating your eyes daily with the same scale, and count how often you reach for drops. After four to eight weeks, compare the average severity and the number of severe days before and after the change. That comparison is much more reliable than a general impression, and it guides your eye doctor's next step.
Should I track dry eyes and dry mouth separately?
Yes. They are different problems with different causes and treatments, even though some conditions affect both. Screens, wind and eyelid gland problems dry the eyes without touching the mouth, while mouth breathing, CPAP, dehydration and some medications mainly dry the mouth. Tracking them as two symptoms shows whether they move together, which is more typical of anticholinergic medications or an autoimmune cause such as Sjögren's disease, or independently, which points to local causes. Trace Health has Dry Eyes and Dry Mouth as separate symptoms so each gets its own chart, and both appear side by side in the doctor-ready PDF.
