Nobody in this world is born with the ability to see things properly. Conversely, there are many babies who are born with nearsightedness that they can not see close-up objects clearly. 

Seeing is actually a learned skill. In detail, the development vision in babies needs sufficient light stimulation, which allows normal neurological processes. Both normal development of retinal cells and the transmission of impulses to the brain depends on the initial simulation. 

Lazy eye or amblyopia is a common problem that occurs mostly in children. It is estimated that four in every hundred people suffer from this condition.

In normal cases, the baby after birth must learn to use their two eyes together while doing visual tasks. However, some children are eventually diagnosed with a lazy eye because one eye is not functioning properly for an extended period.

Weak eye or eyes that are unused officially called an amblyopic eye. A lazy eye may also cause a loss of vision. People with normal vision in both eyes have normal muscle around them that work together to focus properly. 

However, the amblyopic children have muscle imbalances that cause the brain to reject the image of a weak eye. It is also acceptable to say that the brain inhibits the normal function of the eye that is weak. Fortunately, lazy eye can be treated in children and adults.
