More About the Cardiff Acuity Test for Low Vision
The Cardiff Acuity Test for Low Vision uses 45 cards with vanishing optotypes that are familiar to children to test for low vision. The procedure functions as a game in order to attract and hold the attention of a young child.
The test uses the Preferential Looking technique - where the examiner assesses the subject based on their eye movements ,rather than requiring recognition of the image or answers from the test subject. This method enables young children and individuals of all ages with intellectual impairment to be tested accurately.
