When Do Babies Grow Out of Being Cross Eyed
As a parent, you might be curious to know when babies see colors and start distinguishing between them. This post has all the answers regarding babies' color vision.
As is the case with any developmental milestone, such as crawling, walking, or talking, babies learn to see and distinguish between different colors over a period of time. It generally takes about a year for their vision to reach the normal levels of adults and three to four years to develop fully (1) (2). However, this may vary among babies as every baby develops at their own rate.
Keep reading as we tell you all you need to know about babies' color vision milestones in the first 12 months. We also acquaint you with certain vision problems that you should watch out for.
When Do Babies See Colors?
A neonate's eyes are slightly bigger than half the size of that of a grown-up and have limited focus, approximately eight to ten inches.
A newborn can differentiate between light and dark at birth. They begin to track objects in the first week, but it could take a few weeks before they see their first primary color. And it is believed that by the time they are five months old, they see the full spectrum of colors (2) (3).
What Colors Can Babies See?
Newborns can only see black, white, and shades of grey. They start to see their first primary color — red, in the first few weeks after birth and see the full spectrum of colors by five months. By the time they are 12 months, they should be able to distinguish between even the different hues and shades of colors (2).
The following are the common vision-related milestones of babies in their first year. Note that the rate at which each baby reaches these milestones may vary (2) (4) (5) (6).
At birth
- Blinks when their eyes are touched or in response to bright light
- Makes uncoordinated eye movements
- Focuses on an object placed as close as eight to ten inches (approximately the distance between the mother's face and the baby when held in the arms for feeding).
- Can regard or appreciate a human face.
One to three months
- Starts to hold their gaze for a longer time and smiles when you approach closer
- Tears begin to form
- Can track a moving object up to 90 degrees
- High-contrast colored patterns and toys draw the infant's attention
- Can recognize familiar objects
- Looks at hands
Four to six months
- Hand-eye coordination improves, thus enabling the baby to reach out to an object and hold it
- Can identify and stare at a face or an object at a farther distance
- Eyesight develops to recognize various colors
- Looks at their own hands or in the mirror
- Can turn the head and pick up a toy from the floor by the sixth month
Seven to nine months
- Depth perception (judgment regarding distance) improves
- Shows preference for certain colors
Ten to twelve months
- Can gaze at an object moving at high speed
- Memorization improves
- Can pull themselves up using support
- Can judge distance well and throw things with precision
How Do Babies See Color In The First Year Of Life?
A newborn's vision develops rapidly during the first year of life. Learning about how an infant grows to see the beauty of the world by perceiving the colors is fascinating. Here's a rough timeline of how they see color in their first year of life (2) (6).
Birth to three months
- At birth, a neonate's vision is poor. At first, they can see objects only in black, white, and hues of grey.
- They have an underdeveloped central vision.
- The first primary color that they see is red.
- During the second and third months, the photoreceptors slowly develop and help the infant distinguish green and red colors within a meter's length.
- Parents can introduce highly contrasting images or toys of these colors, including black and white, within the periphery of their view to draw their attention and develop their vision.
Four months to six months
- This is considered a crucial period in the development of a baby's color vision as they get introduced to other colors.
- In the fourth month, the baby starts seeing the bold primary colors, including green, red, blue, and yellow, along with certain hues of these colors.
- With the onset of binocular vision, infants recognize large geometric shapes of these colors.
- By the fifth and sixth months, their vision further develops, and they see the full spectrum of colors, including the pastels.
- They are also able to differentiate between light and dark shades to an extent.
Seven months to nine months
- The baby's vision and depth perception improve further.
- Their visual acuity improves, and they see objects with better clarity.
- The baby begins to understand the three-dimensional world around them, aiding their response to different hues of colors.
Ten months to twelve months
- By one year, your baby should have accomplished chromatic vision almost similar to an adult. A slight delay is not a cause for worry.
- A one-year-old's eyes can recognize any color and hue.
- They would have developed decent levels of visual acuity.
What Warning Signs Should Parents Watch Out For In The First Year?
As a baby's vision develops quickly during the first year, it is crucial the parents remain attentive and look for signs of any eye or visual problem to avoid future complications.
Although vision problems are quite rare in infants, consult their optometrist promptly if you notice any of the following signs and symptoms of vision problem (5) (7).
- Abnormal alignment or movement of the eyes (usually after six months)
- Extreme light sensitivity. This might be due to increased pressure in the eyes.
- Frequent turning of the eyes
- Poor visual tracking
- Redness of the eyes
- Teary or watery eyes
- Inability to focus on familiar objects
- Grey or white pupil
- Not able to focus on objects or follow them by two months
Parents should take their infants for regular eye exams to determine the baby doesn't suffer from eye problems such as strabismus and nystagmus (8) (9).
Crossed eyes (Strabismus)
- It is a kind of misalignment of an eye.
- The squinting might not only be inward, but also upward, downward, or outward.
- When left untreated, it could lead to amblyopia.
Nystagmus
- It refers to the fluttering of the eyes, wherein they oscillate rapidly in horizontal, vertical, or circular motion and is often characterized by blurriness.
- Nystagmus can be congenital or acquired and may be noticed around six weeks to several months in the newborn.
- If an abnormal development of the optic nerve is the cause of nystagmus, the baby may have poor vision.
When Do You Know If The Baby Is Color Blind?
The baby's inability to recognize colors such as red, green, brown, or orange indicates color blindness.
The symptoms of color blindness generally become apparent when your baby is in pre-school. You could suspect color blindness if your infant is extremely sensitive to light and has excellent night vision.
Consult your infant's optometrist to rule out eye problems, such as glaucoma, macular degeneration, cataracts, or diabetic retinopathy, which could be risk factors (10) (11).
Does My Baby Need An Eye Doctor Yet?
Routine eye checkups are a must to ensure the perfect eye health of your baby.
According to the American Academy of Ophthalmology and the American Academy of Pediatrics, newborns, especially premature babies or ones with a family history of eye disorder, should be examined for general eye health by the pediatrician in the hospital nursery to rule out infections, defects, cataracts, or glaucoma. And at six months, the baby's eyes should be checked for alignment and vision maturity as part of the well-child visits (11).
An infant's vision develops quickly in their first year of life. Observe your baby's vision-related milestones in the first year closely, and take them for regular checkups. If you suspect any vision problem, consult an optometrist or pediatrician promptly.
