SightKeeper

SightKeeper is a comprehensive vision care companion designed for iPhone users who want to take an active role in monitoring and protecting their eyesight. Through the app, users can perform a range of self-administered visual
astigmatism screenings, all calibrated to the specific pixel density of their device for accurate on-screen measurements. Beyond testing, SightKeeper logs
every result into a long-term personal record, helping users observe gradual
changes over weeks and months rather than relying on isolated snapshots. The app also offers daily eye-protection routines, blink reminders, screen-time
guidance, and curated knowledge cards covering common refractive conditions, dry eye, and pediatric vision habits.

What sets SightKeeper apart from generic wellness apps and basic vision testers is its tightly integrated workflow: testing, tracking, education, and habit-building all live inside a single coherent experience, rather than being scattered across separate tools. Calibration is handled automatically using the device's display profile, results are visualized as longitudinal trends
instead of one-off scores, and the protection module nudges users toward sustainable daily habits rather than overwhelming them with clinical jargon.

The problem SightKeeper solves is the gap between sporadic clinical eye exams and the constant strain modern screens place on our eyes. By making frequent, structured self-checks effortless, it gives users an early-warning system and the awareness needed to act before small issues become permanent.
