In short, yes.
A study published in JAMA Ophthalmology validated three at-home visual acuity (VA) tests in comparison with in-office visual acuity.
The study details.
Between July 2020 and April 2021, 121 participants with VA of 20/200 or better were randomly assigned to self-administer two of three at-home visual acuity tests (printed chart, mobile phone app, or website) within 3 days before their standard of care clinic visit.
Participants also completed a survey assessing usability of the at-home tests. At the clinic visit, best-corrected Snellen distance acuity was measured as the reference standard.
What did they find?
Compared with in-office visual acuity measurements, all three at-home tests were accurate within 1 line of Snellen acuity.
What phone app and website were used for this study?
The Verana Vision Test mobile phone app and the Farsight.care website were used as at-home tests.
Why is this info helpful?
Because having at-home visual acuity tests validated through comparison with in-office visual acuity measurements supports their potential use in telehealth care.
