Your child can see 20/20 with glasses—but are both eyes working well together? 👁️👁️
When one eye has a much higher prescription than the other, called anisometropia, clear eyesight may not tell the whole story.
A 2026 study in children with myopic anisometropia found that greater differences between the eyes were associated with subtle changes in focusing balance, eye coordination, binocular fusion, and depth perception—even among children with good corrected vision and without clinically significant binocular-vision symptoms.
💡 20/20 tells us how clearly your child sees. It doesn’t tell us everything about how the two eyes work together.
