Newborn children have poor vision and can only see the outline of very close objects. At about half a year of age, children may have the ability to follow close objects. At 1-2 years of age, the child may have about 0.2-0.3 vision; at 3-4 years of age, the child may have about 0.6 vision; at 4-5 years of age, the child may have about 0.7 vision; at about 6-7 years of age, the child may have about 0.8-1.0 vision when the child’s vision reaches the normal standard. If the child has a large difference in vision in both eyes, or has significantly lower vision than children of the same age, it is recommended to go to the hospital for an atropine dilated eye exam to check the child’s refraction and rule out amblyopia. If amblyopia is present in the child, active treatment is required.
