Parents should be aware of signals of poor vision. If one eye turns or crosses, that eye may not see as well as the other eye. If the child is uninterested in faces or age-appropriate toys, or if the eyes rove around or jiggle (
nystagmus), poor vision should be suspected. Other signs to watch for are tilting the head and squinting. Babies and toddlers compensate for poor vision rather than complain about it.Should a baby need
glasses, the prescription can be determined fairly accurately by dilating the pupil and analyzing the light reflected through the pupil from the back of the eye.A baby's vision can also be tested in a research laboratory where brain waves are recorded as the child looks at stripes or checks on a TV screen. The test is called Visual Evoked Potential (VEP). Another test called preferential looking or Teller Acuity Cards uses simple striped cards to attract the child's attention. In both tests, as the stripes grow smaller, the child eventually does not respond (with brain waves or by looking at the stripes).

What is strabismus?
By the BabyCenter editorial staff, from: http://www.babycenter.com/refcap/baby/babyills/babyeyes/10890.html
If your baby's eyes seem to point in different directions or not focus on the same object, he may have strabismus ? a lack of coordination between the eyes. They may appear to be "crossed" or one may seem to drift inward, outward, or upward. Strabismus can be constant (meaning the eyes are always crossed or misaligned) or intermittent (meaning it happens now and then). If your baby has strabismus and it isn't treated, his brain could start ignoring the input from one of his eyes, eventually causing the vision in the ignored eye to deteriorate. This condition is known as Amblyopia or "Lazy eye" (see below). Depth perception could also be damaged.
What causes it?
Sometimes strabismus is present at birth. The condition seems to run in families, but can also show up in children with no family history ? and when that's the case, it sometimes indicates a more significant vision problem. Those who are farsighted also seem to be at higher risk.
What can be done to treat strabismus?
Strabismus that's a result of farsightedness can usually be corrected with glasses, especially if caught early. Strabismus that persists even when a child wears glasses may require surgical correction. While the lack of coordination between the eyes centers in the brain, it's not possible to operate on the brain to change the alignment of the eyes. Instead, doctors operate on the eye muscles, which are accessible. That's one reason that the surgery isn't 100 percent successful.
