EyeChart is a pocket vision screener: randomized Snellen, Sloan, Tumbling E, and Landolt C 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 EyeChart! 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.


In addition to our free features, EyeChart offers a subscription to exclusive paid features, including the Randomizable Near Vision Chart, Line Isolation, Amsler Grid, and Single Optotype Charts! The subscription costs $0.99 per month of access, and 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.

Great functional APP

I’m a provider in a busy urban ED. Our eye charts are sometimes blocked by patients/equipment in the hallways. This app is great because I can use it anywhere- in our trauma bay, in an ED room, in the hallway! I love how you can get a brand new chart with a single touch. I love how you can get the symbol chart (perfect for peds/non English speaking patients). Simple and functional. Five stars.

Good app

Good app does what it says it will.

To Kotchy - Get your facts straight, you CAN have better than normal (20/20) vision. The 1st number is how far away the person stood from a full size chart. The 2nd number is how far away a person with normal vision could stand from the full size chart & still read the same row of letters. Therefore, a person with 20/15 vision can read at 20 feet what a person with normal vision can only read at 15 feet, thus better than "normal" vision. Note that each eye can also have different results.
