Babies can see at birth, but it takes time for them to develop their visual abilities to differentiate colors, change focus from one thing to another, and coordinate their eyes together to watch things move. Babies cannot see all colors until they are around 5-6 months, and may not have 20/20 visual acuity until around their second birthday. As your growing toddler plays, explores, and moves about his world, he develops increasingly accurate visual-perceptual skills including depth perception, spatial skills, visual memory, and shape recognition.
