What is the Pelli-Robson test?

Answer: 

This test is similar to the Snellen test where the optometrist asks you to identify the letters you can see on a chart. However, the Pelli-Robson test uses printed letters of decreasing contrast with three letters at each contrast level. The test is designed to identify patients with poor contrast sensitivity.
