Your baby can see from birth, but her vision is quite blurry at first. Her sight will develop gradually over her first year. By the time your baby is a year old, she'll see the world almost as well as you do.  By the time your baby is one month or two months old, she'll have learned to focus her eyes. This means she can follow a toy if you move it around in front of her. If you pass a rattle in front of her face, it will transfix her. Or you can play eyes-to-eyes by moving very close to her face and slowly moving your head from side to side. Your baby's eyes will lock on to yours.
