Summary
This study aims to compare a home vision self-assessment test to office-based Snellen visual acuity in myopic children.
Eligibility
Inclusion Criteria3
- Age ≤ 18 years.
- Both sexes.
- Patients who completed the home visual acuity test and have a subsequent office-based visual acuity test.
Exclusion Criteria6
- Last in-office visual acuity of 20/125 or worse in both eyes (to allow for a buffer of at least 2 lines of vision from the upper limit of 20/200 on the home vision assessment).
- Lack of access to MyChart.
- History of keratopathy, cataract, glaucoma, retinal detachment, neuro-ophthalmic disease, or other eye diseases.

- History of systemic diseases.
- Severe psychological or psychiatric diseases.

Interventions
Patients will be asked to use the 5 feet distance for standardization, which allows for visual acuity assessment from 20/16 to 20/200. Patients will be asked to wear their current corrective lens for distance, to take the test at home in a place with good lighting and to test each eye separately. Office-based vision testing will be performed by a trained ophthalmic technician in a dimmed room with the Snellen chart illuminated on a screen. Patients will be asked to wear their current corrective lens for distance and an eye occluder will be used to test each eye separately.
