Children Vision FAQ's

Q How often should children have their eyes examined?

A According to the American Optometric Association (AOA), infants should have their first comprehensive eye exam at 6 months of age. After that, kids should have routine eye exams at age 3 and again at age 5 or 6 (just before they enter kindergarten or the first grade). For school-aged children, the AOA recommends an eye exam every two years if no vision correction is needed. Children who need eyeglasses or contact lenses should be examined annually.

Q My 5-year-old daughter just had a vision screening at school and she passed. Does she still need an eye exam?

A Yes. School vision screenings are designed to detect gross vision problems. But kids can pass a screening at school and still have vision problems that can affect their learning and school performance. A comprehensive eye exam by an optometrist can detect vision problems a school screening may miss. Also, a comprehensive eye exam includes an evaluation of your child’s eye health, which is not part of a school vision screening.

Q What is vision therapy?

A Vision therapy (also called vision training) is an individualized program of eye exercises and other methods to correct vision problems other than nearsightedness, farsightedness and astigmatism. Problems treated with vision therapy include amblyopia (‘lazy eye”), eye movement and alignment problems, focusing problems, and certain visual-perceptual disorders. Vision therapy is usually performed in an optometrist’s office, but most treatment plans also include daily vision exercises to be performed at home.

Q Can vision therapy cure learning disabilities?

A No, vision therapy cannot correct learning disabilities. However, children with learning disabilities often have vision problems as well. Vision therapy can correct underlying vision problems that may be contributing to a child’s learning problems.

Q My daughter (age 10) is farsighted and has been wearing glasses since age two. We think she may have problems with depth perception. How can she be tested for this, and if there is a problem, can it be treated?

A We can perform a very simple stereopsis test to determine if your daughter has normal depth perception. In this test, she wears “3-D glasses” and looks at a number of objects in a special book or on a chart across the room. If she has reduced stereopsis, a program of vision therapy may help improve her depth perception.

Q My 7-year-old son's teacher thinks he has “convergence insufficiency.” What is this, and what can I do about it?

A Convergence insufficiency (CI) is a common learning-related vision problem where a person’s eyes don’t stay comfortably aligned when they are reading or doing close work. For reading and other close-up tasks, our eyes need to be pointed slightly inward (converged). A person with convergence insufficiency has a tough time doing this, which leads to eyestrain, headaches, fatigue, blurred vision and reading problems. Usually, a program of vision therapy can effectively treat CI and reduce or eliminate these problems. Sometimes, special reading glasses can also help.

Q My son is 5 years old and has 20/40 vision in both eyes. Should I be concerned, or could this improve with time?

A Usually, 5-year-olds can see 20/25 or better. But keep in mind that visual acuity testing is a subjective matter – during the test, your child is being asked to read smaller and smaller letters on a wall chart. Sometimes, kids give up at a certain line on the chart when they can actually read smaller letters. Other times, they may say they can’t read smaller letters because they want glasses. (Yes, this happens!) Also, if your son had his vision tested at a school screening (where there can be plenty of distractions), it’s a good idea to schedule a comprehensive eye exam to rule out nearsightedness, astigmatism or an eye health problem that may be keeping him from having better visual acuity.

Q My daughter has been diagnosed with refractive amblyopia due to severe farsightedness in one eye. She just got her glasses and the lens for her bad eye is much thicker than the other lens. She complains that the glasses make her dizzy and she refuses to wear them. Can anything be done about this?

A In situations like this, where one eye needs a much stronger correction than the other, contact lenses are a better option. With glasses, the unequal lens powers cause an unequal magnification effect, so the two eyes form images in the brain that are different in size. This can cause nausea, dizziness because the brain may not be able to blend the two separate images into a single, three-dimensional one. And, of course, the glasses will be unattractive because one lens will be much thicker than the other. Even if your child is quite young, she can probably handle contact lens wear. Contact lenses don’t cause the differences in image magnification that glasses do. Continuous wear lenses (worn day and night for up to 30 days, then discarded) or one-day disposable lenses may be good options. Keep in mind that amblyopia is a condition where one eye doesn’t see as well as the other, even with the best possible correction lens in place. Simply wearing the contacts may not improve the vision in her weak eye. Usually a program of vision therapy will also be needed.

Are Contact Lenses a Good Choice for Kids?

A common question many parents have about contact lenses and kids is: "When is my child old enough to wear contact lenses?" Physically, your child’s eyes can tolerate contact lenses at a very young age. Some babies are fitted with contact lenses due to eye conditions present at birth. And in a recent study that involved fitting nearsighted children of ages 8-11 with one-day disposable contact lenses, 90% had no trouble applying or removing the contacts without assistance from their parents.

A Matter of Maturity

So the important question is whether or not your child is mature enough to insert, remove and take care of their contact lenses. How they handle other responsibilities at home will give you a clue. If your child has poor grooming habits and needs frequent reminders to perform everyday chores, they may not be ready for the responsibility of wearing and caring for contact lenses. But if they are conscientious and handle these things well, they may be excellent candidates for contact lens wear, regardless of their age.

Contact Lenses for Sports

Many kids are active in sports. Contact lenses offer several advantages over glasses for these activities. Contacts don’t fog up, get streaked with perspiration or get knocked off like glasses can. They also provide better peripheral vision than glasses, which is important for nearly every sport. There are even contact lenses with special tints to help your child see the ball easier. For sports, soft contact lenses are usually the best choice. They are larger and fit closer to the eye than rigid gas permeable (GP) lenses, so there’s virtually no chance they will dislodge or get knocked off during competition.

Glasses are still required

If your child chooses to wear contact lenses, they still need an up-to-date pair of eyeglasses. Contact lenses worn on a daily basis should be removed at least an hour before bedtime to allow the eyes to “breathe.” Also, there will be times when your child may want to wear their glasses instead of contact lenses. And contact lenses should be removed immediately any time they cause discomfort or eye redness.

Don’t push contacts on your kids

Motivation is often the most important factor in determining whether your son or daughter will be a successful contact lens wearer. If you wear contact lenses yourself and love them, that still doesn’t mean they are the right choice for your child. Some children like wearing glasses and have no desire wear contact lenses. We can usually tell at your child’s contact lens consultation if they really want to wear contact lenses. If it appears that they would rather stay in glasses, we will certainly respect their decision – and you should, too. Sometimes it’s just a matter of timing. Often, a child may feel they don’t want contacts, but a year or two later, they do. There’s always time to make that decision.

When your child is ready to try contacts

When you and your child agree it’s time for contacts, call our office to schedule a contact lens consultation. We welcome the opportunity to help kids of all ages enjoy wearing contact lenses.

Controlling Nearsightedness in Children

Myopia (nearsightedness) is a common vision problem affecting children who can see well up close, while distant objects are blurred. Nearsighted children tend to squint to see distant objects such as the board at school. They also tend to sit closer to the television to see it more clearly.

Sometimes, childhood myopia can worsen year after year. This change can be disconcerting to both children and their parents, prompting the question: “Will it ever stop? Or, someday will this get so bad that glasses won’t help?”

Myopia that develops in childhood nearly always stabilizes by age 20. But by then, some kids have become very nearsighted. Here are three possible ways to slow down the progression of myopia in children:

Bifocals

Some evidence suggests wearing eyeglasses with bifocal or progressive multifocal lenses may slow the progression of nearsightedness in some children. The mechanism here appears to be that the added magnifying power in these lenses reduces focusing fatigue during reading and other close work, a problem that may contribute to increasing myopia. A five-year study published in the February 2007 issue of Investigative Ophthalmology & Visual Science produced an interesting result involving nearsighted children whose mother and father were also nearsighted. These children, who wore eyeglasses with progressive multifocal lenses during the course of the study, had less progression of their myopia than similar children who wore eyeglasses with regular, single vision lenses.

Gas permeable contact lenses

Wearing rigid gas permeable contact lenses (also referred to as “RGP” or “GP” lenses) may slow the progression of nearsightedness in children. It’s been proposed that the massaging action of the rigid GP lens on the eye during blinking may keep the eye from lengthening, thereby reducing the tendency for advancing nearsightedness. In 2001 to 2004, the National Eye Institute (NEI) conducted a controlled study to determine whether wearing GP lenses is effective in slowing the progression of myopia in children. The 116 participants in the study were 8 to 11 years old when the research began.

At the end of the three-year study period, the children who wore GP lenses had only 0.63 diopter (D) less nearsightedness than the kids in the control group who wore soft contact lenses. The study also found that wearing GP lenses does not slow the growth of the eye, which causes most of the myopia in children. The reduced progression of myopia among those children wearing GP lenses was due only to the effect the lenses had on the front surface of the eye (the cornea). Children who wore the GP lenses had less increase in corneal curvature than those who wore soft contact lenses. The NEI researchers believe these GP lens-induced changes in corneal curvature are not likely to be permanent, and therefore the effect of GP lenses on controlling myopia progression may not be permanent.

Orthokeratology

Orthokeratology, or “ortho-k,” is the use of specially-designed gas permeable contact lenses to flatten the shape of the cornea and thereby reduce or correct mild to moderate amounts of nearsightedness. The lenses are worn during sleep and removed in the morning. Though temporary eyeglasses may be required during the early stages of ortho-k, many people with low to moderate amounts of myopia can see well without glasses or contact lenses during the day after wearing the corneal reshaping lenses at night. Recent research suggests ortho-k may also reduce the lengthening of the eye itself, indicating that wearing ortho-k lenses during childhood may actually cause a permanent reduction in myopia, even if the lenses are discontinued in adulthood.

Learning-Related Vision Problems

There’s no question that good vision is important for learning. Experts say more than 80% of what your child is taught in school is presented to them visually. To make sure your child has the visual skills they need for school, the first step is to make sure your child has 20/20 eyesight and that any nearsightedness, farsightedness and/or astigmatism is fully corrected with glasses or contact lenses. But there are other, less obvious learning-related vision problems you should know about as well.

Good vision is more than 20/20 visual acuity

Your child can have “20/20” eyesight and still have vision problems that can affect their learning and classroom performance. Visual acuity (how well your child can see letters on a wall chart) is just one aspect of good vision, and it’s not even the most important one. Many nearsighted kids may have trouble seeing the board in class, but they read exceptionally well and excel in school. Other important visual skills needed for learning include:

Eye movement skills – How smoothly and accurately your child can move their eyes across a printed page in a textbook.
Eye focusing abilities – How well they can change focus from far to near and back again (for copying information from the board, for example).
Eye teaming skills – How well your child’s eyes work together as a synchronized team (to converge for proper eye alignment for reading, for example).
Binocular vision skills – How well your child’s eyes can blend visual images from both eyes into a single, three-dimensional image.
Visual perceptual skills – How well your child can identify and understand what they see, judge its importance, and associate it with previous visual information stored in their brain.
Visual-motor integration – The quality of your child’s eye-hand coordination, which is important not only for sports, but also for legible handwriting and the ability to efficiently copy written information from a book or chalkboard.

Deficiencies in any of these important visual skills can significantly affect your child’s learning ability and school performance.

Many kids have vision problems that affect learning

Many kids have undetected learning-related vision problems. According to the College of Optometrists in Vision Development (COVD), one study indicates 13% of children between the ages of 9 and 13 suffer from moderate to severe convergence insufficiency (an eye teaming problem that can affect reading performance), and as many as one in four school-age children may have at least one learning-related vision problem.

Signs and symptoms of learning-related vision problems

There are many signs and symptoms of learning-related vision disorders, including:

Blurred distance or near vision, particularly after reading or other close work
Frequent headaches or eye strain
Difficulty changing focus from distance to near and back
Double vision, especially during or after reading
Avoidance of reading
Easily distracted when reading
Poor reading comprehension<
Loss of place, repetition, and/or omission of words while reading
Letter and word reversals
Poor handwriting
Hyperactivity or impulsiveness during class
Poor overall school performance

If your child exhibits one or more of these signs or symptoms and is having problems in school, call us to schedule a comprehensive children’s vision exam.

Comprehensive children’s vision exam

A comprehensive children’s vision exam includes tests performed in a routine eye exam, plus additional tests to detect learning-related vision problems. These extra tests may include an assessment of eye focusing, eye teaming, and eye movement abilities (also called accommodation, binocular vision, and ocular motility testing). Also, depending on the type of problems your child is having, we may recommend additional testing.

Vision therapy

If it turns out your child has a learning-related vision problem that cannot be corrected with regular glasses or contact lenses, then reading glasses or vision therapy may help. Vision therapy is a program of eye exercises and other activities specifically tailored for each patient to improve their vision skills.

Vision and learning disabilities

A child who is struggling in school could have a learning-related vision problem, a learning disability or both. Vision therapy is a treatment for vision problems; it does not correct a learning disability. However, children with learning disabilities may also have vision problems that are contributing to their difficulties in the classroom. After your child’s comprehensive vision exam, we will advise you about whether a program of vision therapy would be helpful.

Vision Therapy for Children

Many children have vision problems other than simple refractive errors such as nearsightedness, farsightedness and astigmatism. These “other” vision problems include amblyopia (“lazy eye”), eye alignment or eye teaming problems, focusing problems, and visual perceptual disorders. Left untreated, these non-refractive vision problems can cause eyestrain, fatigue, headaches, and learning problems.

What is vision therapy?

Vision therapy (also called orthoptics or vision training) is an individualized program of eye exercises and other methods to treat non-refractive vision problems. Vision therapy is usually performed in an optometrist’s office, but most treatment plans also include eye exercises to be performed at home. Optometrists who focus their practice in vision therapy and the treatment of learning-related vision problems are sometimes called behavioral optometrists or developmental optometrists. Vision therapy is approved by the American Optometric Association (AOA) for the treatment of non-refractive vision problems, and there are many studies that demonstrate its effectiveness. The degree of success achieved with vision therapy, however, depends on a number of factors, including the type and severity of the vision problem, the patient’s age and motivation, and whether the patient performs all eye exercises and visual tasked as directed. Not every vision problem can be resolved with vision therapy.

Vision therapy is customized and specific

The activities and eye exercises prescribed as part of a vision therapy program are tailored to the specific vision problem (or problems) a child has.

Vision therapy and learning disabilities

Vision therapy does not correct learning disabilities. However, children with learning disabilities often have vision problems as well. Vision therapy can correct underlying vision problems that may be contributing to a child’s learning problems. Be sure to tell us if your child has been diagnosed as having a learning disability. Often, vision therapy can be a helpful component of a multidisciplinary approach to remediating learning problems.

Schedule a comprehensive eye exam

If you suspect your child has a vision problem that may be affecting their performance in school, the first step is to schedule a comprehensive eye exam so we can determine if such a problem exists. If learning-related vision problems are discovered, we can then discuss with you whether a program of vision therapy would be helpful.

Your Infant's Visual Development

One of the greatest moments after the birth of your baby is when your newborn makes eye contact with you. The visual system of a newborn infant takes some time to develop. In the first week of life, your newborn’s vision is quite blurry. It takes several months for your child’s vision to fully develop. Knowing the expected milestones of your baby’s vision development during their first year of life can insure your child is seeing properly and enjoying their world to the fullest.

During your pregnancy

Your child’s vision development begins before birth. How you care for your own body during your pregnancy is extremely important for the development of your baby’s body and mind, including their eyes and the vision centers in their brain.

Be sure to follow the instructions your obstetrician (OB/GYN doctor) gives you regarding proper nutrition and the proper amount of rest during your pregnancy. And of course, avoid smoking and consuming alcohol or drugs during pregnancy, as these toxins can cause multiple problems for your baby, including serious vision problems.

At birth

At birth, your baby sees only in shades of gray. Nerve cells in their eyes and brain that control vision aren’t fully developed. Also, their eyes don’t have the ability to change focus and see close object clearly. So don’t be concerned if your baby doesn’t seem to be focusing on objects right away, including your face. It just takes time. (Despite these limitations, studies show that within a few days after birth, infants prefer looking at an image of their mother’s face over anyone else’s.)

The first month

Color vision develops in the first few weeks of life, so your baby is starting to see the world in full color. But visual acuity and eye teaming takes a bit longer -- so if your infant's eyes occasionally look unfocused or misaligned, don't worry.

The eyes of infants are not as sensitive to visible light as adult eyes are, but they need protection from the sun's harmful UV rays. Keep your baby's eyes shaded outdoors with a brimmed cap or some other means.

Months 2 and 3

Your baby’s vision is improving and their two eyes are beginning to move better as a team. They should be following moving objects at this stage, and starting to reach for things they see. Also, infants at this stage are learning how to shift their gaze from one object to another without having to move their head.

Months 4 to 6

By 6 months of age, significant advances take place in the vision centers of the brain, allowing your infant to see more distinctly, move their eyes faster and more accurately, and have a better ability to follow moving objects with their eyes.

Visual acuity develops rapidly, improving from about 20/400 at birth to about 20/25 at six months of age. Your child’s color vision should be nearly fully developed at age six months as well, enabling them to see all the colors of the rainbow with ease. Children also develop better eye-hand coordination at 4 to 6 months of age. They’re able to quickly locate and pick up objects, and accurately direct a bottle (and many other things) to their mouth.

Months 7 to 12

Your child is now mobile, crawling about and covering more distances than you might have expected. They are also better at judging distances and more skilled at locating, grasping and throwing objects, too. During months 7 to 12, your child is developing a better awareness of their overall body and learning how to coordinate their vision with their body movements. At this time, watch them closely to keep them from harm as they explore their environment. Keep cabinets that contain cleaning supplies locked, and put a barrier in front of stairwells.

When its time for an eye exam

If you suspect something is seriously wrong with your baby’s eyes in their first few months of life (a bulging eye, a red eye, excess tearing, or a constant misalignment of the eyes, for example) take your child to a pediatric ophthalmologist or other eye doctor immediately. For routine eye care, the American Optometric Association (AOA) recommends you schedule your baby’s first eye exam when they are six months old. Though your baby can’t yet read letters on a wall chart, your optometrist can perform non-verbal testing to determine visual acuity, detect excessive or unequal amounts of nearsightedness, farsightedness and astigmatism, and evaluate eye teaming and alignment. At this exam, your doctor will also check the health of your baby’s eyes, looking for anything that might interfere with normal and continuing vision development. We welcome providing eye care for even the youngest children. For more information about eye exams for kids or to schedule your child’s first eye exam, please call our office.
