Good-Lite LEA Grating Acuity Test

The LEA Grating Acuity Test at full contrast requires discrimination of the direction of long lines, which is a more demanding task than the detection acuity measured with LEA Gratings. The test gratings are shown to children and adults at different distances to determine which distance the direction of lines can be perceived. Knowing the distance and which grating was used, the grating acuity values can be read from the nomograms.
