Important: If you notice sudden changes in your vision from one day to the next, contact your eye doctor immediately!

Quick Start Guide

1. Put on glasses or readers if needed.

2. Ensure your face is well-lit with soft, even lighting—avoid harsh shadows.

3. Position your iPhone or iPad about 15 inches away from your face. You’ll need both hands for these assessments!

4. Make sure no other faces are looking at your screen.

5. Cover only one eye at a time—use high elbows to help keep your face in view.

6. Follow the on-screen instructions.

7. If you don’t see any distortions, tap the "Next" button to move on.

8. If you do see distortions, trace the affected area while keeping your eye on the dot, then tap "Next."

9. Complete all 4 assessments and tap "Done" when finished.

10. If you see distortions, share your results with your eye doctor.
