Most school screenings test just the sharpness of distance eyesight, so many vision problems that affect learning go undetected. But parents and teachers can learn to spot learning-related visual problems. Some of these signs are on the following checklist. If a child is continually exhibiting any of these signs, it's time to arrange for a behavioral vision evaluation. Child holds head at an extreme angle to the book when reading.
Child covers one eye when reading.
Child squints when doing near vision work. Constant poor posture when working close. The child moves his or her head back and forth while reading instead of moving only eyes. Poor attention span, drowsiness after prolonged work less than arm's length away Homework requiring reading takes longer than it should.
