This excellent review provides a concise overview of child visual development from birth to 12 months. The page also includes tips on how to ensure your child is developing well.
Children should be assessed for visual dysfunction by 12 months, and then again periodically through to age 5. This is a great time to have a closer look at the finer elements of motor control and focusing to ensure the child is ready for reading and hours of near work. We can generally expect that a child’s refractive error (degree of optical correction needed for 20/20 vision) will be established by about 3 years for children born at full term.
