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.
App was free a few days ago now patients have to pay because they need it because of covid19Pretty bad and lacking human decency
Developer Response
The app has been a paid app since day 1, and App Store does NOT allow a free app to become a paid app. There had been a 1 week promotion during which the purchase price was zero.
Shame on you for profiteering during COVID pandemic!
Reviewforyou*
Profiteering during this crisis when people and companies should be trying to help is unconscionable. Many families are unemployed due to the COVID pandemic and cannot afford to spend valuable resources on an app at this time. Be part of the solution, not the problem at this difficult time. Shame on you! This app was free until just a few days ago. During this COVID crisis, most eye care providers are resorting to telemedicine to monitor patients who need to be followed. This app is useful for visual acuity testing, especially in children, since it includes the Lea and HOTV charts and could be very helpful in the setting of telemedicine. It had been a free app until just a few days ago, when all of a sudden, in the midst of the COVID-19 pandemic, a $4.99 fee was charged. This fee should be removed or at least waived at this time—just as quickly as it was added!

Better than Snellen chart on paper
WilliamsPiggy
I have been wondering how come the top row of the Snellen chart could be suitable for both 20 feet and 6 meters, as marked in paper base Snellen charts, since 20 feet is 6.096 meters. This app actually gives slightly larger optotype for a 20 feet distance than for a 6 meters distance. The UI design is mobile friendly. The hint is brief, so it took me some fail and try to figure out how to use. After all, intuitive and smooth.
This was free - now it’s not.

Update #2: Why are you reporting my concern to Apple support? My issue is NOT about MY purchase experience. My issue is about the many other patients who will need this app in the near future. Give THEM a break. Reduce the price for THEM. HELP THEM, not me. ================Update: If it was just a temporary 1 week free trial, why not extend that for several more weeks to help people out? Or maybe reduce the price to $0.99? Seems like that would be reasonable if you are restricted from changing it to free. ================Hundreds of patients will now suffer as they can’t afford spending money on a single visual acuity check. Shame on the developer for taking advantage of the disadvantaged. Hold down on the comment and like it so it rises to the top of most helpful. Time to look for another option.

App Store does NOT allow a free app to become a paid app, and this app has been a paid app. And you may request a refund from App Store. There had been a 1 week promotion during which the purchase price was zero.
* Trend graph now supports LogMAR, Decimal, MAR, and 5-Point notations, in addition to VAS.
* The VA notation is now based on your device's region by default, and can be overridden in Settings.
