Patti Pics optotypes are highly calibrated to Sloan optotypes and follow criteria such as the Snellen 5x5 grid, equal difficulty, equal blur at threshold, and high recognizability. Patti Pics are great for testing children. Back side of chart features a MassVat design that helps to isolate the lines and help ease testing. MassVat design also helps in the detection of diseases such as Amblyopia.
