Healthy eyesight is hugely important to a child’s development and education.
As much as 80% of all learning is visual, and it’s estimated that more than half of childhood learning difficulties come from undiagnosed vision problems. What can parents do to ensure their kids don’t have to struggle with the social and educational disadvantages of an undiagnosed vision problem?
Vision Problems a School Nurse Might Miss:
Inability of children to self-report isn’t the only reason a vision problem might go undiagnosed. Another big one is that many of them don’t receive comprehensive eye exams before starting school. School nurses will test students’ visual acuity using the big E chart, but healthy eyesight is a lot more complicated than having 20/20 vision. Here are some vision problems the school nurse will miss:
Astigmatism. Refractive errors that cause blurry vision but which aren’t always caught in a vision screening. Can lead to amblyopia if not treated with corrective lenses.
Amblyopia. Also known as “lazy eye,” this means poor vision in one eye due to astigmatism, a difference in refractive errors between the two eyes, or crossed eyes. Can result in irreversible vision loss without treatment.
Convergence Insufficiency. The eyes drift outward when trying to focus on up-close things, making reading and other close tasks difficult.
Strabismus. A misalignment of the eyes where they turn out, in, down, or up. Can be corrected by patching, special glasses, or surgery.
