PV Numbers charts are a usable alternative to Tumbling "E" and Landolt "C" charts. Although patients may not be familiar with the Roman Alphabet, or speak the same language, they may be familiar with numbers. The number chart allows the patient to simply sign or gesture the correct number they see. This simplicity helps to make testing in multiple languages easier, quicker and more reliable.
