Kids’ Eye Exams

Most parents are used to taking their children to the pediatrician and the dentist for regularly scheduled checkups.   However, many parents don’t realize that their children should also have regular eye exams – even if the child doesn’t wear glasses.  Why?

Eye problems are very common in children.  The American Optometry Association (AOA) estimates that 1 in 4 children has a vision-related condition.  Left untreated, these conditions can have a serious effect on a child’s learning, development, athletic performance, and overall health.

Appropriate vision testing at an early age is vital to insure your child has the visual skills he or she needs to perform well in school.  A child who is unable to see print or view a blackboard can become easily frustrated, leading to poor academic performance. Some vision problems, such as lazy eye, are best treated if they are detected and corrected as early as possible while the child’s vision system is still developing.

• Poor vision directly affects learning.   When a child has difficulty focusing or cannot see things clearly, his learning and attention can suffer.   In fact, the American Optometric Association has estimated that 60% of learning disabilities are associated with vision problems: when a child is suspected of having ADD/ADHD or another learning disorder, a comprehensive eye examination probably makes sense as well.
• Eye problems can affect development.  Poor vision can affect not only learning and behavior but also can affect a child’s physical and neurological development.  Eye muscle imbalances (called strabismus, or commonly “crossed eyes” or “wandering eyes”), for example, can lead to amblyopia (“lazy eye”) in which the brain suppresses vision from one eye to avoid seeing double.  This can lead to permanent vision loss if untreated.
• Eye problems can also affect physical abilities and athletic performance.  Vision irregularities or eye muscle imbalances can affect depth perception, leading to “clumsiness,” tripping, and poor hand-eye coordination.
• While very rare, children sometime experience more serious eye conditions such as cancerous tumors (retinoblastoma, medulloepithelioma), congenital glaucoma, retinal disease, etc. that can cause blindness and even be life-threatening.

That’s why it’s so important to have your kids’ eyes screened regularly by an optometrist.

Parents might not even think about whether your baby has a vision problem unless there are signs of a vision problem. But we recommend eye exams for infants because early identification of a child’s vision problem is key; children often are more responsive to treatment when problems are diagnosed early.  So, we recommend that infants should have their first comprehensive eye exam at 6 months of age. Children then should have additional eye exams at age 3, and just before they enter the first grade — at about age 5 or 6.

You might wonder, “How can you give my baby an eye exam?  We know she’s the smartest baby in the world, but get real.  She can’t talk yet and she sure can’t read an eye chart just yet.”  Even though your baby can’t tell us that she’s having problems seeing, we can still perform a surprisingly thorough exam.  For example, we can tell how your baby’s doing with focusing ability, color vision, and depth perception at as early as six months of age.
We can test your baby’s:

• Pupil responses- that is whether the eye’s pupil opens and closes properly in the presence or absence of light.
• Ability to fixate and follow- that is whether your baby’s eyes are able to fixate on and follow an object —  such as a light —  as it moves. Infants should be able to fixate on an object soon after birth and follow an object by the time they are 3 months old.
• Visual acuity- that is how well your baby sees.  Since we’ve yet to have a six month old who can read letters and numbers on the eye chart, we use a test for “Preferential Looking” where we show your baby cards that are blank on one side, but with stripes on the other side.  Typically, infants and children will look at the more interesting stripes (if they can detect them) rather than at the blank field.

If your child’s a bit older, you might wonder, “My kid is two and can’t read yet. How can you give him an eye exam?”
You’d be surprised!  Parents are sometimes amazed to learn that we can provide comprehensive eye exams to preschooler even if they don’t know their alphabet or if they’re too shy to verbalize.
We can administer eye tests designed specifically for preschoolers, including:

• Visual acuity- instead of using the eye charts we letters, we use charts using LEA Symbols, such as an apple, house, square, and circle.
• Random dot-  stereopsis testing uses special patterns of dots and 3-D glasses to measure how well your child’s eyes work together as a team.
• Retinoscopy- we shine light into the eye to observe the reflection from the back of the eye (retina); this test helps us determine your child’s ocular health, and even the right eyeglass prescription.
