If your baby has been diagnosed with or you suspect when should my baby have their vision screened, here is what the evidence says.

The short answer

Vision screening starts at birth with the red reflex test and continues at every well-child visit. The AAP recommends formal instrument-based vision screening (photoscreening) starting at age 1-3 years and traditional visual acuity screening by age 4-5. Early detection of vision problems is critical because many conditions are most treatable when caught in infancy and early childhood.

Key takeaways

  • Vision screening starts at birth with the red reflex test and continues at every well-child visit. The AAP recommends formal instrument-based vision screening (photoscreening) starting at age 1-3 years and traditional visual acuity screening by age 4-5. Early detection of vision problems is critical because many conditions are most treatable when caught in infancy and early childhood.
  • Usually normal when: Your baby has a normal red reflex at birth and subsequent visits
  • Call your doctor if: You notice a white or abnormal pupil reflex in your baby's eye, especially in photos (could indicate retinoblastoma or cataract)
  • Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”

This is one of the most common questions parents ask. Searching for answers means you care.

What Parents Should Know

According to AAP, NIH, CDC guidelines, vision screening starts at birth with the red reflex test and continues at every well-child visit. The AAP recommends formal instrument-based vision screening (photoscreening) starting at age 1-3 years and traditional visual acuity screening by age 4-5. Early detection of vision problems is critical because many conditions are most treatable when caught in infancy and early childhood. At 0-3 months, your pediatrician checks the red reflex at birth and at early well visits. The red reflex test shines a light into each eye looking for the normal reddish glow from the retina. An abnormal red reflex may indicate cataracts, retinoblastoma, or other conditions. Your pediatrician also checks for structural eye abnormalities and observes eye alignment. It is generally considered normal when your baby has a normal red reflex at birth and subsequent visits. However, you should contact your pediatrician promptly if you notice a white or abnormal pupil reflex in your baby's eye, especially in photos (could indicate retinoblastoma or cataract).

By Age

What to expect by age

0-3 months

Your pediatrician checks the red reflex at birth and at early well visits. The red reflex test shines a light into each eye looking for the normal reddish glow from the retina. An abnormal red reflex may indicate cataracts, retinoblastoma, or other conditions. Your pediatrician also checks for structural eye abnormalities and observes eye alignment.

3-6 months

By 3-4 months, your baby should be able to follow moving objects and make eye contact. Your pediatrician assesses eye alignment and movement at well visits. Occasional eye crossing before 4 months can be normal, but constant or persistent crossing needs evaluation. By 6 months, eyes should be well-aligned.

6-12 months

Your pediatrician continues to check eye health at well visits. If there is any concern about eye alignment (strabismus), lazy eye (amblyopia), or other issues, a referral to a pediatric ophthalmologist is made. Treatment for these conditions is most effective when started early.

12-24 months

Instrument-based screening (photoscreening) can be performed starting at age 1 and is recommended by the AAP between ages 1-3. This involves taking a quick photo of your child's eyes that can detect focusing problems, strabismus, and other abnormalities. The test is painless and takes seconds.

2-3 years

Photoscreening should be performed if not already done. By age 3, some children can participate in visual acuity testing using pictures or shapes. The US Preventive Services Task Force recommends vision screening at least once between ages 3-5. If your child has risk factors (family history, prematurity, developmental delays), earlier or more frequent screening is recommended.

What to Tell Your Pediatrician

  • Describe when you first noticed when should my baby have their vision screened and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if your baby does not seem to follow objects or make eye contact by 3 months.
  • Mention if you notice one eye turning in or out, even occasionally, after 4 months of age.
  • Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
  • Bring a list of any questions or observations you want to discuss at the appointment.

What Should You Do?

When to take action

Probably normal when...
  • Your baby has a normal red reflex at birth and subsequent visits
  • Your baby follows faces and objects with their eyes by 3-4 months
  • Both eyes move together and are aligned by 6 months of age
  • Your baby passes photoscreening or other vision tests at recommended ages
Mention at your next visit when...
  • Your baby does not seem to follow objects or make eye contact by 3 months
  • You notice one eye turning in or out, even occasionally, after 4 months of age
  • You notice your baby consistently tilting their head to one side when looking at things
Act now when...
  • You notice a white or abnormal pupil reflex in your baby's eye, especially in photos (could indicate retinoblastoma or cataract)
  • Your baby's eye is suddenly misaligned, bulging, or you notice sudden vision loss or behavior suggesting your baby cannot see

What You Can Do at Home

  • Keep track of when you notice when should my baby have their vision screened — noting the time of day, duration, and any triggers can help your pediatrician.
  • Remember that your baby has a normal red reflex at birth and subsequent visits — this is generally within the range of normal.
  • At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
  • Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
  • While monitoring at home, seek immediate care if you notice a white or abnormal pupil reflex in your baby's eye, especially in photos (could indicate retinoblastoma or cataract).

My Baby Needs Glasses - What Should I Know?

Babies can be prescribed glasses as young as a few months old for conditions like significant farsightedness, nearsightedness, astigmatism, or to help correct eye alignment issues. Infant glasses have flexible frames, adjustable straps, and polycarbonate lenses for safety. While it may seem early, correcting vision problems in infancy is crucial for normal brain visual development and can prevent lazy eye (amblyopia).

My Baby Needs Eye Patching for Lazy Eye

Eye patching (occlusion therapy) is a standard treatment for amblyopia (lazy eye). By covering the stronger eye, the brain is forced to use the weaker eye, strengthening its visual pathway. Treatment is most effective when started early, ideally before age 3-4. Your ophthalmologist will prescribe the number of hours per day based on severity. Consistency is more important than perfection - any patching helps.

Eye Alignment Issues in Infants

Eye alignment issues (strabismus) in infants can involve one eye turning inward (esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia). Intermittent misalignment in newborns under 3-4 months is very common and usually resolves as eye muscles strengthen. Constant misalignment at any age, or any misalignment persisting after 4 months, should be evaluated by a pediatric ophthalmologist. Many parents also mistake pseudostrabismus (the appearance of crossed eyes caused by a wide nasal bridge) for true misalignment.

When Should My Baby See a Pediatric Ophthalmologist?

A pediatric ophthalmologist is a medical doctor specializing in eye conditions in children. Referral is appropriate for eye misalignment (strabismus), suspected lazy eye (amblyopia), abnormal red reflex, cataracts, excessive tearing from blocked tear ducts that have not resolved, eye injuries, and failed vision screening. These specialists can examine babies of any age and determine if glasses, patching, surgery, or other treatment is needed.

My Baby's Head Shape Looks Abnormal

Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.

Achondroplasia (Dwarfism) in Babies

Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
