Sightly helps parents organize their child's eye health records, connecting each exam, axial length changes, and everyday eye care. See the changes, understand the trends, and give daily eye care more direction. Record every exam. Keep the full picture. Record vision, refraction, axial length, and other measurements. Save report photos, OCR text, and doctors' notes. Turn scattered exam information into a clear history you can revisit at your next appointment. See axial length changes. Understand growth trends. Review axial length and refraction changes and explore growth rates over time. With Sightly Plus, view trend forecasts and forecast ranges for the next 12–36 months, explore same-age comparisons, and compare new exams with previously saved forecasts. Log daily eye care. Get to know your habits. Use Sightly Plus to log multiple activities at once and review outdoor time and near work. Activity timers, calendars, weekly reports, and habit summaries based on complete recording days help you discover routines worth keeping or adjusting. Connect your exams with everyday life. With Sightly Plus, review eye care logs between two exams alongside axial length changes. Make your records more meaningful, from each follow-up to your daily routine. Also includes follow-up, medication, and lens-care reminders; FAQs about axial length and everyday eye care; PDF summaries for doctor visits; and backup and restore, including eye care activities. Available on iPhone and iPad in six languages. Sightly supports record keeping, trend references, and communication with clinicians. It does not provide diagnoses or treatment advice. Forecasts and research-population references involve uncertainty and cannot replace clinical exams or a doctor's judgment. Data is stored locally on your device by default. Sightly does not upload local records to the cloud unless you choose to export, share, or restore a backup.
