A one-month-old baby can typically see objects best that are about 8 to 12 inches (20 to 30 centimeters) away from their face, roughly the distance to a parent's face during feeding or holding

. At this age, babies are nearsighted and see distant objects as blurry; their vision is still developing and not yet clear for far distances

. They may briefly focus on faces or brightly colored objects within about 3 feet, but their central vision is still maturing

. In terms of visual acuity, a one-month-old has an average acuity around 20/235, meaning they need to be much closer to an object to see it clearly compared to adults

. Their eyes are not yet fully coordinated, and their ability to track or focus on moving objects is just beginning to develop

. In summary, a one-month-old infant sees best at close range, about 8 to 12 inches, with distant vision being blurry and limited. Their visual system is rapidly developing but far from adult-level clarity at this stage
