During childbirth vision is very poor. A typical child can see just huge items moving before his face. This poor vision is expected predominantly to youthful visual focuses in the mind. These visual focuses develop as the eye is fortified with visual information. Amid the initial three months of life there is an exceptionally fast change in vision. These initial couple of months are important to the point that they are known as the critical period of visual development.

The development of good vision is reliant on very much engaged pictures amid this time. In the event that there is a variation from the norm in the eye that blocks this engaged picture, these vital visual focuses in the cerebrum won't create. This is the reason it is so vital to perceive correctable conditions that interfere with vision in this early period.
