Q: My child saw 20/20 at their school physical. That's perfect vision for back to school, right?

A: Maybe! 20/20 only tells us what size letter can be seen 20 feet away. People with significant farsightedness or eye muscle imbalances may see "20/20", but experience enough visual strain to make reading difficult. Vision controls eighty percent of learning so include a thorough eye exam in your child's Back-to-School list.
