  • Title: Test charts for distance preferred for low-vision.
    Author: Fonda G.
    Journal: Ann Ophthalmol; 1987 May; 19(5):178-80. PubMed ID: 3592477.
    Abstract:
    Two wall test charts with Snellen letters on both sides have been designed for the purpose of testing vision accurately, especially for the patient with low vision. Visual designations of 20/160 (6/48) and 20/125 (6/37.5) are included on the chart. This makes each line 26% larger. Sloan letters are used and arranged so that each line is of equal difficulty.
