According to “Visual Acuity Testing for Telehealth Using Mobile Applications” published in JAMA Ophthalmology on https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7809609/ , Visual Acuity Charts demonstrated the highest accuracy among 10 iPhone-based visual acuity chart applications.

Myopia detection requires several steps, and distant visual acuity testing is often the first. A decline in visual acuity may signal myopia development, enabling early intervention.

Disclaimer:
While this app may replace eye charts in print, however it CANNOT replace doctors and optometrists who carry out comprehensive eye exam for your basic eye health. The eye chart app does not test strabismus, esotropia, exotropia, hyperopia and astigmatism and which are common early vision conditions. Please visit optometrists regularly and seek help from medical professional at early signs of visual acuity problems.
