Vision is one of the most critical tools for your child’s development. Since children don’t always know that what they see isn’t "normal," they rarely complain of blurry vision. They simply adapt to the world as they see it.
This guide is designed to help you understand how your child’s sight develops, what we look for during our check-ups, and the subtle signs that might point to a vision issue.
What Does Normal Vision Development Look Like?
The visual system is immature at birth with maturation developing rapidly during the first years of life.
- Newborns: Newborns can detect movement and see lights, shapes, and faces. They see best at about 8 to 12 inches away - roughly the distance to your face while holding them. By 4 weeks they can fixate on a parent’s face. It is normal for a newborn’s eyes to sometimes wander or cross, however this should resolve by 4 months of age.
- 2 Months: Babies should be able to track an object moving horizontally in front of them.
- 4 Months: By this age most babies are able to follow moving objects with their eyes. They can detect and reach for nearby objects, and they love observing the activities happening around them
- 6 Months: Depth perception begins to develop around 5 months of age. By 6 months a baby should have good color vision and should be able to differentiate and recognize people and objects.
- 1 - 2 Years: Toddlers experience significant development in depth perception and hand-eye coordination.
- 3 - 5 Years: By the preschool years most children can see as well as an adult and vision should be approaching the standard 20/20 visual acuity.
Vision Exam and Screening at Annapolis Pediatrics:
The eye exam is an important component of each physical, beginning on the first day of life.
Eye Exam:
- External eye: The external eye exam includes visualization of the eyelids, conjunctiva (white of the eye), cornea, pupil, and iris.
- Red reflex: This is similar to the red-eye effect in photos. This tells us if light is reaching the retina at the back of the eye properly.
- Pupillary response: This checks to see that the pupils constrict and dilate appropriately when light is shined into the eyes.
- Ocular alignment: We check to make sure both eyes are looking in the same direction and eye movement is coordinated.
- Ophthalmoscopy: Using a special light we look at the back of the eye to check critical structures such as the retina and optic disc. This can be performed in older, cooperative children.
Instrument Based Screening: We use instrument based vision screening at each well visit between 2 and 5 years old. The device we use looks like a large camera and can quickly detect if your child needs a more extensive eye evaluation by an ophthalmologist.
What are Some Signs of a Vision or Eye Problem?
Because children are masters of compensation, vision issues can be subtle. Keep an eye out for these "red flags":
- Physical Signs:
- One eye drifting inward or outward (strabismus) persisting after 4 months of age.
- An unusual tilt of the head when looking at things.
- Drooping eyelids.
- White or grayish white color of the pupil.
- Eye redness lasting more than a few days.
- Behavioral Signs:
- Frequent eye rubbing (when not tired).
- Not fixing, following, and recognizing objects at expected ages.
- Sitting very close to the TV or holding books right against their face.
- Squinting, frequent blinking, or closing one eye to see better.
- Eyes that are overly sensitive to light.
- Unexplained headaches or "tired eyes" after school.
How to Keep Young Eyes Healthy
Early detection and treatment of eye problems is vital, as many conditions are much easier to treat while the brain and eyes are still developing. If you notice any of the warning signs above, be sure to bring them up with your pediatrician.
Beyond regular check-ups, you can protect their vision with these lifestyle habits:
- Encourage Outdoor Play: Spending time outside helps maintain healthy vision. It allows children to practice focusing on objects at various distances and provides natural sunlight exposure, which studies suggest may reduce the risk of nearsightedness.
- Manage Screen Time: While screens don't permanently "ruin" eyes, they cause significant strain and dryness. To prevent this, follow the American Optometric Association’s 20-20-20 Rule:
- The 20-20-20 Rule: Every 20 minutes, have your child look at something at least 20 feet away for at least 20 seconds.
Your child’s vision is critical to their development, learning, and confidence. If you have even a small "hunch" that something isn't right, trust your gut and give our office a call!
