A Vision Breakdown by Age and What to Expect as Your Child Ages

August 14th, 2019

Knowing factors that can impact your child’s eye health can help you be prepared. Having healthy vision could aid in the physical, cognitive, and social development of your child putting them on a positive path for their health and well-being. Understanding what happens to your child’s vision as they age can help you face triumphs and warning signs as they approach. Take a moment and review this vision breakdown by age and what is expected.


A vision breakdown of babies and what to expect:

Smoking can harm an unborn child’s eyes. Smoking during pregnancy increases the risk of premature birth. Preemies are more likely to have permanent vision loss or even blindness. Smoking while pregnant also leads to a five-fold higher risk of the baby getting bacterial meningitis. Bacterial meningitis can cause severe vision loss.

During a baby’s first months, their central vision is still developing. A newborn baby can see, but they are still forming connections between their retina and their brain. As central vision develops, a baby may begin to focus on objects dangled right in front of them.

By age 3 months, a baby’s eyes should focus and follow objects. In the first two months of life, an infant’s eyes may appear to cross or wander out to the sides. This is usually normal. As visual coordination improves, the baby’s eyes will work together to focus and follow a moving object. If you do not notice this happening consistently by age 3 months, talk with your pediatrician.

By age 5 months, babies are seeing in three dimensions. At this age, babies get better at reaching for objects because they can see how far an object is from them. They are developing depth perception. They may even remember what an object is if they only see part of it.

Around age 9 months, babies’ eyes have turned their final color. Eye color depends on the amount and distribution of a brown pigment called melanin in the iris. Light-colored eyes at birth may darken if melanin develops. It is not uncommon, however, to see slight changes in eye color during the first three years of life.

Children can get cataracts too, congenitally or after birth. Without proper treatment, pediatric cataracts can cause abnormal connections between the brain and the eye that may become irreversible. The good news is cataracts are often discovered during the eye screening at birth, or at subsequent pediatric vision screenings.

Toddlers1 (Age 1-5)

A vision breakdown of toddlers and what to expect:

Watch for misalignment, or one eye that looks straight ahead while the other eye turns inward, outward, upward, or downward. This may be a sign of strabismus, a visual problem that occurs in about 4% of children in the U.S. The ability of both eyes to focus on an object simultaneously continues to develop until about age 7. Be sure to seek evaluation early if you suspect a problem.

Measles is a leading cause of childhood blindness worldwide. The virus can harm the eyes and vision in numerous ways.

Keep toddlers away from cleaning products. Young children are more likely than working-age adults to get eye damage from chemical burns. These burns are particularly dangerous because they can cause permanent damage to both external and internal eye structures. If a child does get chemicals in the eyes, flush them with plenty of water and proceed to your nearest emergency care department.

School-age children1 (5-18)

A vision breakdown of school-age children and what to expect:

Many school-age children are naturally farsighted. In most cases, they do not need glasses. Children generally can accommodate by using their focusing muscles to see clearly near and far. As they age, children’s eyes grow and lengthen, and farsightedness often improves on its own. Significant farsightedness, however, can lead to strabismus and amblyopia (“lazy eye).

Good screen time hygiene may help lower the risk of myopia and digital eye strain. To help combat this, encourage your child to follow the 20-20-20 rule: Look up from the screen every 20 minutes and focus at least 20 feet away for 20 seconds. Read more tips here on how to relieve eye strain.

Some not-so-obvious signs of childhood vision problems are 1) quick loss of interest in activities that require extensive eye use, 2) losing your place when reading and 3) turning the head to look at something in front of you. If you observe one or more of these symptoms in your child, schedule an eye exam with an ophthalmologist.

Blue light from digital devices is not dangerous for your children’s eyes. But screen time should be limited late in the day to prevent sleep problems from blue light. Skip the glasses that claim to protect eyes from blue light. They lack evidence to support their claims.

Colorblindness is much more common in boys and the symptoms can be hard to detect. Parents may only notice a problem when a child is learning colors. One symptom is the inability to tell the difference between shades of the same or similar colors. This happens most with red and green, or blue and yellow.

Eye injuries are the most common cause of blindness in children.

Baseball is a leading cause of eye injuries in children ages 14 and older. Regular eyeglasses and sunglasses do not offer sufficient protection from sports-related eye injuries. In fact, they can shatter on impact, causing even more damage to the eyes. Children should wear sports eye protectors made with polycarbonate.

More than 90 percent of children’s eye injuries can be prevented with protective goggles. 

Proper contact lens care is challenging for children and teens. This puts them at higher risk for serious eye infections that can cause impaired vision or even blindness. Watch to be sure they care for their lenses properly.

Good vision is key to a child’s physical, cognitive, and social development. Attending your scheduled routine eye exams are important for detecting and correcting eye problems early to set your child on a positive path for their health and well-being into their adult years. Also, creating a good eye health routine for you and your child can aid in better eye health. Using products like Tozal®, vitamins for your eyes, ComfortClear® to remove debris from the eyelids and lashes, and Zenoptiq™ to kill viruses and bacteria* on the eyelids and lashes is a good way to start a new eye health routine.
