Out of all the senses, sight is the least developed at birth.
The anatomical development of the eyes begins very early in foetal development, starting at week 3 and completing by week 10, but there is a big difference between the physical eye development and visual development.
At birth a baby’s vision is limited, so the world appears blurry. Because of this it's much easier for a newborn to see very high contrast things - therefore black and white objects attract their attention most easily and in doing so fascinate them.
By around 6-8 weeks of age babies can focus on your face more easily, and it's when you might notice that gorgeous first smile being returned right back to you.
Babies are actually born with the receptor cells to detect colour, but these are still immature so it takes time for these cells to develop and critically for the brain to make sense of the signals from them.
It is now believed that by around 2 months old, babies will be able to tell a strong red and green apart, and by around 4-5 months they will be able to distinguish blue and yellow. More subtle, pastel-like colour detection will come much later on in their development.
By 4-5 months babies have also developed their binocular vision. Binocular vision, or simply put both eyes working together to create one single image, is not something that babies are born with. Their brains need to learn how to co-ordinate the images received from each eye and blend them into one single picture.
It's a complex process and one that takes at lot of practice to get right (and it's why you'll see very young babies go cross-eyed quite regularly), but once they master it they can start to appreciate 3D vision - so gaining depth perception.
It is at this point that you'll notice more accuracy in their grabbing of objects as the world around them makes a bit more sense all of a sudden - and it's been about 4 months in with both of my girls that I've had my hair cut into a bob to avoid the very accurate, and painful, hair pulling....
Because of the leap in babies' visual development, our products come in two age ranges - 0-4 months for babies as young a few days old to 4/5 months and then 5+ months, for when their colour vision has improved significantly. Each design contains a range of scales within it to ensure that it provides stimulation for many months.
