Read below for more information on the clinical evaluations. Useful for: - Triaging - House visits - Hospital rounds - Emergency rooms - Schools - Patients who have memorized the office chart Eye Chart HD is a pocket vision screener: randomized Snellen, Tumbling E, and other charts to offer a rough but useful screen of visual acuity. Simply press a button to randomize the entire eye chart, or touch an individual line of the chart to randomize that line. Swipe right for the chart selector. Eye care professionals around the world use Snellen Eye Charts to measure visual acuity. However, patients often memorize the classic Snellen chart, leading to less accurate vision measurements. Enter Eye Chart HD! Though this unique, pocket-sized randomizable eye chart should not be used as a primary visual acuity measuring tool, it can provide a handy rough vision screen when a chart is not available, or it can be used to complement static, wall-based Snellen charts. Subscription: In addition to our free features, Eye Chart HD offers a subscription to exclusive paid features, including the Randomizable Near Vision Chart, Line Isolation, Amsler Grid, and Single Optotype Charts! The subscription costs $2.99 per month of access and has to be purchased specially within the app. Once purchased, it is available through an auto-renewing subscription which will renew each month for your convenience until you choose to turn it off. Please let us know if you have any questions about your subscription at eyechartapp@gmail.com. Below is further information on clinical evaluations that have been done. Please do check out the papers cited below if you have concerns. We didn't do these tests and can't speak to them, but we are providing them here for transparency and your reference:  Snellen & Tumbling E charts on Eye Chart HD on iPhone: “Comparison of Visual Acuity Measurement Using Three Methods: Standard ETDRS Chart, Near Chart and a Smartphone-Based Eye Chart Application” Clinical Ophthalmology. Conclusion: “VA measurements with the Near Chart and smartphone-based Eye Chart application corresponded well to the standard ETDRS chart, suggesting potential utility of alternative portable VA tests for in-office or remote vision monitoring, particularly during periods of physical distancing such as the Coronavirus disease 2019 (COVID-19) era” Sloan Chart on Eye Chart HD on iPhone: “Does the EyeChart App for iPhones Give Comparable Measurements to Traditional Visual Acuity Charts?” The British and Irish Orthoptic Journal. Conclusion: “This study found that the VA scores achieved on the EyeChart app are comparable to those achieved using the gold-standard ETDRS chart in a healthy young adult population. This is a promising finding; however, it is necessary for further large-scale studies to investigate the EyeChart app when used on a variety of patient population groups.” Snellen Chart on Eye Chart HD on iPad Mini: “Comparative Study of the Snellen iPad App versus Traditional Light Box Snellen Chart in Distance Visual Acuity” International Journal of Ophthalmology and Clinical Research. Conclusion: “It showed that the results from Eye Chart HD app used in an iPad Mini 2 agreed with the results of the traditional light-box Snellen Chart when used at the Outpatient Department.“ Rapid Vision Screening Chart on Eye Chart HD on iPhone/iPod: “Assessment of a rapid method to determine approximate visual acuity in large surveys and other such settings.” American Journal of Ophthalmology. Conclusion: “An iPod application requiring about a 1-minute testing time provides an objective, portable, rapid, and low-cost method to determine approximate VA, allowing VA testing to be performed efficiently in large surveys and other settings where approximate VA should be measured.” ## Eye Chart HD Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/9c/0d/f2/9c0df2b4-0917-a60c-4a5d-cee237505832/pr_source.png/640x960.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/06/32/ec/0632ec59-012b-bc7d-f689-c3c25375240d/mzl.xcwnfcpo.png/640x960.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/43/fc/d7/43fcd7cc-016a-fe30-5938-1ff986ac1944/mzl.qoxkbzng.png/640x960.png) ## Eye Chart HD Rating Breakdown in United States - 5 stars: 6 (100%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 0 (0%) ## Eye Chart HD Reviews in United States ### ***** "Good for basic test" The randomizing feature on the free eye tests works well. -- Sam Bal, 2025-08-12 ### ***** "Excellent" The best eye chart. Have been using in the ER for years. Excellent. Holding at the end of the bed is approx 4 feet for most patients -- Dr.octagon, 2025-06-10 ### ***** "Best Eye Chart App" Absolutely love this app. PLEASE do not ever take down this app from the app store! This is hands down the BEST, most practical app for use in the hospital. I relied on this app for 10 years throughout medical school and neurosurgery residency. I’ve examined thousands upon thousands of patients with this app and still use it daily. Super fast and lightweight, no frills, loads up instantaneously. Thank you so much to the developers!!! -- Qmutder, 2025-02-05 ### ***** "This app was amazing!" It helped me see how my vision was and was really helpful. 👍🏽 -- okbuddyi, 2020-05-10 ### *---- "Bugged?" I didn’t download or give permission to download this app and it was installed on my phone (no other users, I watched it download after using Youtube). I don’t trust this. -- Mika-tan914, 2018-10-15 ### *---- "Useless to Have to enter your profession every time!" Please stop with asking your profession and your email address every time you open the app. If this is not fixed soon, I will be ending my subscription. -- Lar74, 2018-07-18 ### **--- "NP" Agree with the previous writer. Too many clicks to open the app and don’t like re-entering my email address so frequently. -- hperrotte, 2018-07-05 ### *---- "Too many clicks to open" Every time you open you are asked if you are a professional or home user. Then asked specialty. You are also asked for email address but can simply bypass that. All in all too many clicks to open the app. This should be a one time registration. -- brlittle01, 2018-06-14 ### *---- "Awful" Have to register who you are, what your profession is, every time you open the app. Makes it useless in a professional setting -- Sphingosaurus, 2018-03-11 ### *---- "Painful" I have to register every time I open the app. What a pain -- Nicholasname124, 2017-12-05 [View all Eye Chart HD reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Eye Chart HD Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Grossing | Malaysia | Medical | #45 | | Top Grossing | Nigeria | Medical | #69 | | Top Grossing | Ireland | Medical | #94 | | Top Free | Peru | Medical | #140 | | Top Free | Singapore | Medical | #186 | | Top Free | Hong Kong SAR China | Medical | #199 | | Top Free | Philippines | Medical | #232 | ## Eye Chart HD Discovered Keywords -
