Vision screening may be effective and appropriate at very young ages.,that according to a new study. The U.S. Preventive Services Task Force recently said there wasn't enough evidence to recommend screening children under age 3 for vision problems like Amblyopia.

However, new data from the University of Iowa found testing for such problems was equally effective in kids under age 3 as it was for kids over age 4. The condition, also called 'lazy eye', is highly treatable if caught early.
