An owl 's eye is one-third the size of its head. The pupils are very large to improve night vision. To follow its prey, an owl can swivel its head and twist it around to look backward. Rabbits need to watch for hawks from above and foxes from behind. They have eyes that bulge out on either side of their head.
Teachers can be the first to notice when a child has a vision problem.
The teacher, school nurse, and parents work as a team to provide proper eyecare in a variety of ways. One out of every four children has an undetected vision problem that may impede learning. Eighty percent of what we learn before age 12, we learn through our visual system. In-school vision screenings detect only 20 to 30 percent of vision problems in children. Undetected vision problems can lead to poor grades, low self-image and a negative school experience.
