Question 1

What is dry eye disease?

Accepted Answer

Dry eye disease (DED) is a common condition where your eyes don't produce enough tears or the right quality of tears to stay properly lubricated. It can cause symptoms like burning, stinging, redness, blurry vision, and eye fatigue. An estimated 350+ million people worldwide are affected.

Question 2

How does Ocura screen for dry eye?

Accepted Answer

Ocura uses a combination of a 30-second on-device blink analysis (using your phone's front camera) and four clinically validated questionnaires. The app's AI model synthesizes these results into a personalized severity assessment and care recommendations.

Question 3

Is Ocura a medical diagnostic tool?

Accepted Answer

No. Ocura is a screening and wellness tool designed to help you better understand your eye health. It does not replace professional medical advice, diagnosis, or treatment. If you have concerns about your eye health, please consult a qualified eye care professional.

Question 4

Is my camera data private?

Accepted Answer

Yes. All blink analysis happens entirely on your device. Your video is never recorded, stored, or transmitted. Only computed metrics like blink count and rate are saved — and those stay on your phone unless you choose to create an account and sync.

Question 5

How long does a screening take?

Accepted Answer

A complete screening takes under 10 minutes. The blink test itself is only 30 seconds, and the questionnaires typically take 2-3 minutes each. You can complete them all at once or come back to finish later.

Question 6

Do I need to create an account?

Accepted Answer

No. You can start screening as a guest immediately. If you later create an account, your existing data will be migrated. An account lets you sync data across devices and access longitudinal trend analysis.

Question 7

What are the questionnaires used in Ocura?

Accepted Answer

Ocura uses four published, peer-reviewed clinical instruments: OSDI (Ocular Surface Disease Index) for symptom severity, DEQS (Dry Eye-related Quality of life Score) for impact on daily life, PHQ-9 (Patient Health Questionnaire) for emotional well-being, and CVS-Q (Computer Vision Syndrome Questionnaire) for screen-related symptoms.

Question 8

Is Ocura free?

Accepted Answer

Yes. Ocura is free to download and use on both iOS and Android. All core screening features are available at no cost.

Question 9

Can screen time cause dry eye?

Accepted Answer

Research suggests that prolonged screen use may be associated with reduced blink rate and incomplete blinking, which can contribute to tear film instability and dry eye symptoms. This is one of the factors Ocura helps you monitor and understand.

Question 10

How often should I screen?

Accepted Answer

There's no strict schedule, but periodic screening can help you track changes over time. After 3 or more screenings, Ocura can show you trend analysis. After 5 or more blink tests, predictive insights become available.
