The University of Waterloo Develops New Differential Acuity Test for Children Under Three Years Old

WATERLOO, Ontario—Researchers at the University of Waterloo announced their ongoing development and trials of the Waterloo Differential Acuity Test, or WatDAT, a new eye test based on age-appropriate tasks that can lead to earlier detection and treatment of vision problems in children as young as 18 months. Researchers said this test could enable earlier detection and treatment of common vision problems that affect approximately 14 percent of children aged 2 to 4 including amblyopia or lazy eye, clinically significant farsightedness and astigmatism.
