VISUAL DEVELOPMENT:
1 – 2 YEARS
Exploring their surroundings
By 2 years of age, your child’s eye-hand coordination and depth perception should be well developed. This allows them to eagerly explore their environment[1] and scribble with crayons or pencils.
Clarity of vision (“visual acuity”)[2] and depth perception continues to develop until your child is approximately 5 – 8 years of age. There are still eye problems that can occur during this time that can affect how their vision develops. Before starting school, your child should have an eye examination by an optometrist to check their eye health and make sure their vision is developing properly[3].
