What can my baby see at 1, 3, 6 and 12 months?
Four ages, one at a time: what your baby can usually see, what is only a bonus, and the few signs that are worth asking about.
- At 1 month a baby may focus briefly on you but still prefer bright objects up to 3 feet away, and focuses best at about 20 to 30cm.
- At 3 months the eyes should work together to focus and track. If you do not see that, talk to your paediatrician.
- By 5 to 6 months depth perception is more developed, and reaching for near and far objects improves.
- By 10 months most babies can judge distance well enough to grasp something between thumb and forefinger. Vision keeps sharpening until about age 3 to 5.
- Ask for a check if there is no fixing or following by 3 months, or an eye that stays turned, or a turn that comes and goes after 3 months.
Search for what a baby can see and you meet a wall of ages, each page slightly different. This one keeps to four ages, taken one at a time: 1 month, 3 months, 6 months and 12 months. For each I will say what is expected, what is only a bonus, and what is worth a question. The reasons behind the pattern, how focus, eye muscles and brain come together, are in when can babies see, the first year month by month, and I have tried not to repeat that page here.
One thing before the ages. These are typical ages, not deadlines. A baby who reaches a step a few weeks later than the page says is not failing a test. The few ages that do matter are the ones in the last section.
What can my baby see at 1 month?
At one month your baby may focus briefly on you, but may still prefer brightly coloured objects up to 3 feet away. That is how the American Academy of Ophthalmology describes the age. Newborn eyes are also very sensitive to bright light, and the pupils are small.
The distance that works best is close. The American Academy of Pediatrics gives it as about 8 to 12 inches, which is 20 to 30cm, the usual distance between your face and your baby's at a feed. So a baby who studies you during a feed and then loses interest when you lean back is doing what is expected, not ignoring you.
What I would expect at this age is short looks at a face, a pull towards bold shapes, and eyes that sometimes wander or cross for a moment. What I would not worry about is the wandering on its own. The NHS says squints that come and go are common in babies younger than 3 months and are not usually a cause for concern. What I would not put down to age is an eye that stays turned all the time. That is worth a check at any age.
What can my baby see at 3 months?
At three months the two eyes should work together to focus and track objects. The American Academy of Ophthalmology adds a plain instruction: if you do not notice this happening, talk with your paediatrician. The American Academy of Pediatrics says the same stage brings focus on faces and close objects, and tracking of things that move.
Tracking starts a little earlier. By two months, babies are usually able to follow a moving object with their eyes. By three months it should look smooth and shared between the eyes, not one eye drifting off while the other follows.
You can watch for it without any equipment. Hold a face or a soft toy at that close distance and move it slowly from side to side. A three-month-old will usually look, follow part of the way, lose it and find it again. If your baby never seems to lock onto a face, my baby does not look at me yet goes through the possible reasons and what to do about each.
The random wandering of the early weeks should also be gone or going. The American Academy of Pediatrics puts the end of it at 2 to 3 months, and the next section says what to do if it has not settled.
What can my baby see at 6 months?
By six months your baby judges depth better, reaches for things near and far, and tells one object from another by what it looks like. That is a gradual build, not a switch. The American Academy of Pediatrics lists reaching for close objects and better colour vision by 4 months, with interest in circles and faces. The American Academy of Ophthalmology says depth perception develops more fully by 5 months, and that babies get better at reaching for objects both near and far.
In practice this is the age of the grab that finally lands on the toy, and of a baby who is plainly looking from your face to the object and back. If a toy is held out of reach and your baby tries for it, depth and eye-hand coordination are both being used.
Nothing new in the red-flag list appears at six months. The rule from three months still stands: eyes that work together, and a baby who follows and fixes. If that was true at three months and is no longer true, mention it. A change is as useful to a doctor as a delay.
What can my baby see at 12 months?
By twelve months most babies see well enough to judge distance, pick up small things between thumb and forefinger, and move about on that information. The American Academy of Ophthalmology lists the steps: babies generally start crawling at around 8 months, can judge distance pretty well by 9 months, and can usually grasp something between thumb and forefinger by 10 months. By 12 months most babies are crawling and trying to walk.
A baby this age who can find a crumb on a tray and pick it up is using distance, depth and fine focus together. It is not a test, but it is a useful thing to notice.
The picture is still not adult. The American Academy of Pediatrics says children with normal sight typically match adult vision somewhere around age 3 to 5. So a one-year-old sees a great deal, and sees it less sharply than you do. That gap closes over several years, and it is one reason a child's first formal eye check does not have to wait for letters; how we test eyes before a child can read explains how that works.
How much sharper does my baby's vision get from 3 to 12 months?
A lot sharper. In a 2017 study that tested infants with striped cards, the average acuity on that test was about 1.9 cycles per degree at 3 months, 4.8 at 6 months and 12.9 at 12 months. That is roughly a sevenfold change in nine months. The same study measured 23.7 at 24 months and 31.0 at 36 months, so the fastest gains are in year one and the curve flattens afterwards.
Two cautions about those numbers. They come from one study using a looking test designed for babies who cannot speak, so treat them as a shape of growth, not as a score your baby should hit. And a stripe test is not a letter chart, so I would not translate them into the 20/20 style of numbers parents know. What they show well is that the 3-month baby you are looking at is seeing a blurrier world than the 12-month baby, and that this is normal.
If you ever hear a number for a baby's vision that sounds alarming without context, ask what test it came from. A preferential looking card and a letter chart are measuring in different units.
When should I ask for an eye check?
Ask at three months if your baby is not following or focusing, and ask at any age if one eye turns in or out and stays that way. The American Academy of Ophthalmology says that typical early misalignments are reducing by 2 months and most have resolved completely by 4 months, and that misalignment persisting beyond that, or becoming more frequent or larger, deserves evaluation. The NHS gives the practical line: seek advice for a persistent squint, or for a squint that comes and goes in a child older than 3 months.
The ages that matter, together, are these. No fixing or following by 3 months. An eye that turns constantly at any age. A turn that comes and goes and is still there after 3 months. Add a white or pale glow in the pupil of a flash photo; what a white glow in photos can mean says why that one should not wait. And add a baby who objects strongly when one particular eye is covered. Crossed eyes in newborns has the squint thresholds in full.
Checks are not only for when something looks wrong. In the UK the NHS newborn physical examination, within 72 hours of birth and again at 6 to 8 weeks, includes a look at how the eyes focus and move, using a special torch, and it screens for conditions such as childhood cataract. A baby's first eye check sets out what an eye check looks like here in Malaysia. If your baby was born early, the schedule is different and is described in eye checks after the NICU.
If your baby is a little slower than the ages on this page and everything else is steady, mention it at the next visit and keep watching. If something on the list above is true, do not wait for the next visit. A check that finds nothing is still an answer, and it is the one most parents are glad to have.
- Your baby does not fix on a face or follow a moving face or toy by 3 months.
- One eye turns in or out all the time, at any age.
- A turn that comes and goes is still there after 3 months.
- You see a white or pale glow in the pupil of a flash photo, in one eye or both.
- Your baby objects strongly whenever one particular eye is covered.
