Hello
Most of eye development takes place in first 2 years but development is over at age of 18years.
Recommended eye check up protocol for kids is at age 1,3and 5 years and then annual eye examination
Your son is too young to get his colour vision assessed..
For more information you can read my health tip on "when and why your child needs an eye examination" available on practo healthfeed
