Eye Chart Pro is a randomizable visual acuity exam. It’s remote-controlled, pleasant for patients and providers, and FREE. Similar chart projector functionality usually costs over $1000!

Useful for:
- Triaging
- House visits
- Patients who have memorized the office chart

- Randomizable Snellen Chart
- Randomizable Tumbling E Chart
- Randomize the whole chart or one line at a time
- Smooth interface with animations
- Basic remote
- Metric / Feet functionality


Eye Chart Pro is a generator for randomized Snellen and Tumbling E 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. Tap another button to toggle between Snellen and Tumbling E charts.

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 Pro! Though this unique, notebook 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.

Eye Chart Pro was made with the best of intentions, and we hope to continue improving it. Your feedback is appreciated!

Works Great!

My husband and I used this eye chart on an iPad 2017. We stood 8 feet away and read the chart with our glasses to determine if my husband’s prescription had changed.
***He wants sunglasses for driving, Costco has a sale, and he couldn’t get a appointment with his ophthalmologist before the sale ends.
*** My husband has excellent vision, and he read down to the 20/15 line. I have mild cataracts and read down to the 20/30 line. This app works great!

incredibly easy to use

great for testing vision even in a small room because the chart can be resized. i'm surprised it didn't get a higher rating from previous version.
