The disorder described is strabismus, which is a condition in which the two eyes do not align properly. This can cause double vision and/or amblyopia (lazy eye). Stereopsis refers to the ability to perceive depth through the use of both eyes, tonic neck is a reflexive response to head movement in infants, and perceptual narrowing refers to the tendency for infants and young children to become less able to discriminate between similar stimuli as they age.
