## What is Sighty?

Sighty helps parents keep their child's daily myopia-control routine on track — gently and consistently.

Children on myopia management often follow a daily routine: wearing orthokeratology (ortho) lenses overnight, low-dose atropine eye drops, and spending time outdoors. Missing days is easy. Sighty makes the routine simple to follow and easy to look back on.

• Daily rings — see today's ortho, drops and outdoor time at a glance
• Ortho & outdoor timers — keep counting even when the app is closed; pause, resume and reset
• Atropine log — mark left and right eye, with gentle nightly reminders
• Outdoor goal — track toward a daily target
• Streaks & history — a calendar of every day and how consistent you've been
• Measurements — record axial length and refraction from each clinic visit and watch the trend over the years
• Doctor report — export a clean PDF summary to share at your next visit

Private by design: everything is stored on your device. No account, no sign-in, no tracking.

Sighty Pro (auto-renewing subscription) unlocks axial-length trends, multiple children, and doctor PDF export.

Important: Sighty helps you record and remember your child's routine. It does not provide medical advice, diagnosis, or treatment. Always follow your eye doctor's guidance.
