Newborns are able to see things, but the images of newborns seeing things are different from adults, adults see things more clearly and in three dimensions, newborns can only see very fuzzy images, the child’s nervous system is not well developed, mainly the optic nerve and the brain imaging function are not too perfect, so newborns see people or see other things, are fuzzy. Therefore, parents should not tease their children with brighter objects when they are newborn, which cannot effectively stimulate the development of the optic nerve of the child, parents only need to promote the physical development of the child by slowly conducting sound or touching, stimulating with color is not advisable. After two months the child can gradually see objects, at this time parents can use brightly colored toys to stimulate the child’s nerve development and make his eyes more flexible.
