It’s never too early to begin annual eye exams. In fact, upwards of half of all children are at risk from undiagnosed eye and vision problems which can adversely affect learning at critical points in a child's development. Just like a trip to the pediatrician, a child should receive regular eye exams to maintain healthy vision.
The American Optometric Association recommends that children be evaluated at 6 months, 3 years, and then yearly thereafter.
