Are there any special hints to help with screening 1st grade children for color vision problems?
A. If you are using the Ishihara book, have them trace the lines (with a clean water color paint brush) in the back of the book. The instructions for pass/re-screen are found in the back of the book. If they have normal color vision they will see the same lines as you do, providing you have normal color vision. Some of you have asked about having the child trace the numbers. This is okay, but if they only see one of the numbers, e.g., 7 on the page with the number 74, the question or pass or re-screen is unclear. You may want to invest in one of the books made for unlettered persons or the new Waggoner color vision book which is specifically designed for screening young children.
