It is recommended that your child receive an eye exam at 6 months, 3 years, and before starting Kindergarten. A child's vision is one of their greatest assets, and one of the most overlooked check ups that are needed.
Ensuring your child can see properly is crucial during their developmental years, especially while learning to read and write. Help your child absorb all of that knowledge and don't forget to have their eyes checked as recommended.
