the target grating level as it appears from behind the
non-stimuli paddle whereas the Cardiff Acuity Test and the
Teller Acuity CardsTM II do not require movement of the
target. Limited acuity levels supported

Cardiff Acuity Set - The Cardiff Acuity TestTM is designed
specifically for acuity measurement in children aged 6 months
