PV Numbers are a great alternative vision chart for testing in multiple languages. Even though the patient may not be familiar with the Roman alphabet, often times they will be familiar with numbers. Also, the use of a number chart provides the patient the possibility to simply sign the number they are seeing. This number vision chart is also good for testing some preliterate children, because they may learn or recognize numbers quicker than letters.
