For chronic dry eye disease

Is that $80 eye mask actually working? Now you will know.

TearLog tracks your symptoms, your drops and your environment, then shows you which treatments really move your OSDI score and which ones you are paying for out of habit.

A verdict, not a feelingEvery treatment gets kept or dropped on evidence from your own score.

Reminder apps tell you when. TearLog tells you whether.

The shelf is full of drop timers. None of them answer the question you actually have.

OSDI score tracking

The Ocular Surface Disease Index is the standard questionnaire your eye doctor uses. Answer it weekly and watch one number instead of guessing at a vague sense of better.

Drop and regimen manager

Preservative-free drops, gels, ointments, warm compresses and lid hygiene, each on its own schedule, with the spacing that preservative-free bottles need.

Treatment experiments

Start a new treatment and TearLog watches your score for the weeks that follow, then tells you plainly whether it moved and by how much.

Screen time and weather

Long screen days, dry air and poor air quality all make dry eye worse. TearLog pulls those in automatically and shows how much each one costs you.

Flare diary

The bad days, with what you were doing and where you were. Enough detail to spot the pattern without turning logging into a chore.

Eye doctor PDF

Your OSDI trend, what you have tried, what helped and what did not, on one page. Useful whether you are asking about IPL or arguing with an insurer.

The cost of guessing adds up faster than the treatments

Drops, masks, supplements, punctal plugs, in-office procedures. Most dry eye patients try several at once, then never find out which one was doing the work.
