## Eye Charts Description
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 (

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.

## Eye Charts Reviews in United States

### ****- "Please add 20/400"
Wish this app included 20/400 and beyond. Could you add larger optotypes?
-- J-h-J-h, 2025-01-10

### ***** "Solid app"
My only suggestion is maybe have the letters appear in a row going down. Top can be 20/200 and the bottom is 20/20. Would make great for bedside screening
-- A R , 2023-10-09

### ****- "Please add 20/400"
I see bed side patients and most of them are low vision patients. The VA chart app I used to use is no longer supported so I downloaded this app. This app is great because it allows me to test with numbers (most dementia patients cannot read letters but they can still read numbers) l Wish this app had 20/400 and beyond. Could you add larger optotypes?
-- Jes.H, 2023-01-13

### *---- "Paid $5 for there to be no shapes!!"
My toddler doesn’t know his letters yet but he does know his shapes. I thought it had shapes but it turns out I paid for nothing.
-- MrsMDiaz, 2020-06-02

### ***** "Well written app"
The mirror mode is handy and interesting.
-- Flzxsqc*8, 2020-04-29

### ***** "It looks promising"
Is it possible to have multiple letters in one line for testing lazy eyes?
-- Sandylong99, 2020-04-19

### *---- "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.
-- A-Aron2020, 2020-03-30

### ***-- "What’s the point?"
If free, this would a useful addition to the urgent need for teleophthalmology in the COVID 19 age. But as a charged for app, why bother.
-- eyevoyager, 2020-03-29

### *---- "In times of need"
It’s great you had a promotion for one week. Considering your app is being recognised as well developed maybe you could consider its price during the crisis period as some patients can’t afford $5
-- D0c-@1, 2020-03-27

### **--- "Profiting off of a virus"
App was free a few days ago now patients have to pay because they need it because of covid19
Pretty bad and lacking human decency
-- Emem27, 2020-03-27
