Newborns can not see clearly, even the nearly blind. New at the age of 4 weeks of the baby‘s eyes begin to learn to detect in a single location by blinking. Since her eyes have not been able to clearly distinguish the objects, the new age of 6 months babies begin to distinguish the human faces and monkey faces.

From birth, babies are usually drawn to face encounters. Babies tend to look at all things in a round shape that has two eyes and a mouth in the right place.

But babies have not been able to see clearly, so it can only be seen by the faint. When it enters a new age of 4-5 months, the baby more real preference, and the baby has started to process faces differently from other objects.

As quoted from CNNHealth, the best sensor of the infant visual system is a motion sensor. Motion sensors on the infant visual system, a sensor developed early.

At the age of 4 weeks, infants can detect a flicker stimulus in one location is almost as good as adults. Then around age 7 weeks, babies can distinguish the direction of movement and developments more quickly when the age of 20 weeks.

Motion vision he had seen a baby like raindrops through the windshield of a moving car, would increase dramatically between the ages of 3-5 months and then continue to grow slowly up through middle childhood.

When infants aged 4-5 months, he began to study the maturation of the fusiform face area, a region in the temporal cortex specialized for face processing. This allows normal adult brain specialization can beat the best program in the computer world in detecting subtle differences between faces.

Fusiform face area began activated by faces that are often encountered when entering the infant age of 2 months. Visual experience affects the development of the face that begins in infancy.

When the age of 6 months infants begin to distinguish between monkeys and humans although it is still unclear. Only when the baby is 9 months old, will become better at identifying people and lose the ability to recognize faces of monkeys.

During this period, the baby also becomes better at distinguishing faces within their own racial group than in other racial groups. This is probably because most infants have more visual experience with their own racial group than other races. This process may involve perfecting the process of synaptic connections by experience to improve perceptions of local environmental characteristics.

Visual experience of this baby in motion processing are the most susceptible to interference. Aspects of motion processing may be delayed in some developmental disorders, including dyslexia, autism, fragile-X syndrome and Williams syndrome.

Children who are experiencing vision problems like cataracts from birth will have a different development than normal babies. These conditions cause the infant visual system can not develop as a normal condition. Even up to age 9 months, babies are born with cataracts have not been able to look like other normal babies.

With the baby experienced visual experience, can support the development of infant visual acuity is increasing. But at 3-8 months of age infants have visual acuity of about three times worse than a baby at the age of 5 years of normal.

Global motion perception is influenced by the cataract is only in the first 3 months of life.So the development of infant visual acuity, will keep running well. But parents need to be careful in cases extraordinary, which usually require further attention.
