10月8日的Eye Charts应用程序分析

Eye Charts is a vision testing app independently proven most accurate in a peer-reviewed study (JAMA Ophthalmology). Trusted by parents and clinicians to check, record, and track children's vision since 2018. Early detection of myopia allows you to take preventive action, seek medical advice promptly, and prevent pseudomyopia from worsening into myopia or stop nearsightedness from deteriorating further. INDEPENDENTLY EVALUATED ACCURACY Eye Charts was previously published as Visual Acuity Charts and was independently evaluated in a peer-reviewed study published in JAMA Ophthalmology (https://pmc.ncbi.nlm.nih.gov/articles/PMC7809609/). MORE THAN A DIGITAL EYE CHART Unlike paper charts that can fade, warp, or become memorized, Eye Charts presents randomized optotypes for each test. This helps reduce variability when repeating measurements over time. Choose from: • Snellen • ETDRS • Landolt C • Tumbling E • HOTV • Numbers • Shapes Charts use LogMAR-based sizing and support multiple visual acuity notations, including: • Fraction • LogMAR • MAR • Decimal • VAS FLEXIBLE TESTING Test at different distances to suit small rooms, hallways, clinics, schools, or other available spaces. Eye Charts is self-illuminated on iPhone and iPad, so chart visibility is less dependent on ambient room lighting. Screen brightness can be adjusted, including for longer testing distances such as 6 metres. THREE WAYS TO TEST 1. Doctor and patient — in a clinic or at home 2. Self-test with a mirror — wear an eye patch; the effective testing distance is doubled 3. Self-test with a Bluetooth keyboard — from a few meters away SEE TRENDS, NOT JUST SNAPSHOTS Record test results for individual subjects and visualize changes over time with simple graphs. This makes it easier to notice: • Gradual changes in visual acuity • Stability following an intervention • Differences between visits or repeated tests For parents, this provides a convenient way to monitor a child's visual acuity over time. For healthcare professionals, it provides a practical record for routine screening and follow-up. IMPORTANT MEDICAL NOTICE Eye Charts is a visual acuity screening and measurement tool. It does not replace an examination by an optometrist or ophthalmologist. It does not diagnose eye conditions such as strabismus, esotropia, exotropia, hyperopia, or astigmatism. Regular professional eye examinations are recommended, and you should seek professional medical advice if you notice changes in vision.
