What Is a Pediatric Eye Exam?

A comprehensive pediatric eye exam evaluates how well your child's eyes work together, track, focus, and develop, going far beyond a basic vision screening.

Ellipse Why Pediatric Eye Exams Matter

Children often do not realize they have a vision problem because they assume everyone sees the way they do. Many conditions such as amblyopia, strabismus, and convergence insufficiency are not detected by standard school screenings. The American Optometric Association recommends children receive their first eye exam at 6 months of age, again at age 3, and before starting first grade.

Ellipse Our Kid-Friendly Office

At Insight Vision Optometry, Costa Mesa, our family-friendly office is designed with children in mind, featuring a dedicated children's exam room, kids' optical, and a prize desk to make every visit a positive experience.

What Is Myopia?

Myopia, commonly known as nearsightedness, causes distant objects to appear blurry while close-up vision remains clear and is one of the fastest-growing vision conditions among children.

Ellipse How Myopia Develops

Myopia develops when the eye grows too long from front to back, causing light to focus in front of the retina instead of directly on it. While glasses and contact lenses correct blurry vision, they do not slow the progression of myopia. Left unmanaged, myopia can continue to worsen throughout childhood, increasing the risk of retinal detachment, glaucoma, and cataracts later in life.

Ellipse Myopia Management Options

Myopia management uses proven treatments to actively slow the rate of eye growth in children. Options include specially designed contact lenses such as MiSight 1 Day and orthokeratology (Ortho-K), myopia control spectacle lenses like Stellest, and low-dose atropine eye drops. Starting treatment early gives your child the best chance of reducing their final prescription and protecting their long-term eye health.

Myopia management

What Is Lazy Eye?

Amblyopia, often called lazy eye, is a condition where one or both eyes do not develop clear vision, even with the correct glasses prescription, because the visual pathway between the eye and brain did not develop properly during childhood.

Ellipse Causes of Amblyopia

Common causes of amblyopia include a significant difference in prescription between the two eyes, high refractive error, strabismus (eye turn), or a congenital cataract. Because amblyopia affects how the brain processes visual information, it is not something that can be seen by looking at your child's eyes from the outside. Many children with amblyopia do not realize they have a problem because they have always seen the world this way.

Ellipse Treatment for Amblyopia

Traditionally, patching the stronger eye was the primary treatment for amblyopia. While patching can be effective, it only addresses one eye at a time and does not teach the two eyes to work together. Vision therapy takes a different approach by training the brain to use both eyes as a team, strengthening the weaker eye's connection to the brain while building binocular vision skills. Research supports vision therapy as an effective treatment, especially when combined with other approaches.

Vision therapy vs patching for amblyopia

What Is Strabismus?

Strabismus is a condition where the eyes do not align properly, one eye may turn inward, outward, upward, or downward while the other eye looks straight ahead.

Ellipse Why Strabismus Needs Attention

Strabismus is more than a cosmetic concern. When the eyes are not aligned, the brain receives two different images and may begin to suppress or ignore the input from the turning eye. Over time, this can lead to amblyopia and a loss of depth perception, which affects coordination and daily activities. The misalignment can be constant or intermittent, and may affect one eye consistently or alternate between both eyes.

Ellipse Treatment for Strabismus

Treatment for strabismus depends on the type and severity of the misalignment. Vision therapy works to improve the brain's ability to coordinate the eyes, strengthen eye alignment, and develop proper binocular vision. In some cases, surgery may be recommended to adjust the eye muscles. Vision therapy can play a valuable role both before and after surgery by helping the brain learn to maintain alignment and use both eyes together effectively.

Can vision therapy help before and

What Is Convergence Insufficiency?

Convergence insufficiency is a common vision condition where the eyes struggle to work together when focusing on something up close, such as reading, writing, or using a tablet.

Ellipse Symptoms of Convergence Insufficiency

Children with convergence insufficiency often experience headaches, eye strain, blurred or double vision while reading, difficulty concentrating, and a tendency to lose their place on the page. These symptoms are frequently mistaken for attention or learning difficulties, and many children are misdiagnosed with ADHD or a learning disability before receiving a proper visual evaluation. Convergence insufficiency is not detected by standard vision screenings or a basic eye chart test.

Ellipse Treatment for Convergence Insufficiency

A comprehensive binocular vision evaluation is needed to identify this condition. The good news is that convergence insufficiency responds very well to treatment. Office-based vision therapy, supported by the Convergence Insufficiency Treatment Trial (CITT), is the most effective approach. Through structured, supervised exercises, vision therapy trains the eyes to converge accurately and sustain comfortable near vision for reading and learning.

Convergence insufficiency

What Are Eye Tracking Problems?

Eye tracking, or oculomotor function, refers to the ability to move the eyes smoothly and accurately from one point to another, essential for reading, copying from the board, and following a ball during sports.

Ellipse Signs of Tracking Problems

Children with tracking problems may skip words or lines while reading, use a finger to keep their place, have difficulty copying from the board, or struggle with reading speed and comprehension. They often appear to be "careless" readers, but the underlying issue is that their eyes are not moving efficiently across the page. Oculomotor dysfunction is not something a child will outgrow, and it is not detected by standard school vision screenings.

Ellipse Treatment for Tracking Problems

A comprehensive visual efficiency evaluation can identify whether your child's eye movement skills are developing appropriately. Vision therapy is highly effective for improving eye tracking abilities. Through targeted exercises, children learn to control their eye movements with greater accuracy and coordination, leading to noticeable improvements in reading fluency, attention during close-up tasks, and overall academic performance.

Oculomotor dysfunction eye tracking disorder

What Is Double Vision?

Double vision, or diplopia, occurs when a child sees two images of a single object instead of one, it can happen with one or both eyes open and may be constant or intermittent.

Ellipse Causes of Double Vision

Double vision in children can result from several causes, including strabismus (eye misalignment), convergence insufficiency, or difficulty coordinating the eyes after a concussion or head injury. In some cases, it signals a problem with how the brain is processing and combining the images from each eye rather than a problem with the eyes themselves. Because children often do not know how to describe what they are seeing, double vision can go undiagnosed for months or even years.

Ellipse Treatment for Double Vision

Warning signs include complaints of "the words are moving," frequent headaches, covering one eye while reading, or a noticeable decline in school performance. A thorough binocular vision evaluation can determine the cause and guide the right treatment plan. Vision therapy helps the brain learn to combine images from both eyes into a single, clear picture, reducing or eliminating double vision over time.

What is double vision

What Is Binocular Vision Dysfunction?

Binocular vision dysfunction occurs when the two eyes are unable to work together as a coordinated team, forcing the brain to constantly struggle to merge the images from each eye into one.

Ellipse Symptoms of BVD

Children with BVD may experience headaches, dizziness, difficulty reading, motion sickness, light sensitivity, and trouble concentrating. Many of these symptoms overlap with conditions like ADHD, anxiety, and learning disabilities, which is why BVD is often overlooked. Your child may be working much harder than their peers just to keep the visual world stable and clear. BVD is not something standard vision screenings or basic eye exams are designed to detect.

Ellipse Treatment for BVD

It requires a detailed binocular vision assessment that evaluates how the eyes align and work together at all distances. Treatment for BVD may include specially prescribed prism lenses to help the eyes align more easily, along with vision therapy to strengthen the brain's ability to coordinate the two eyes. With the right care, children with BVD often see significant improvements in comfort, focus, and learning.

Scleral Lenses

Scleral Lenses

If you have keratoconus, an irregular cornea, or have been told contacts aren't an option, scleral lenses can change that. Our fellowship-trained optometrists use wavefront-guided technology and anterior segment OCT mapping to design lenses that vault over the cornea, delivering stable, comfortable vision from morning to night. For the most complex cases, our HERO Scleral lens corrects higher-order aberrations, and EyePrintPRO impression-based lenses provide a truly custom fit when nothing else works.

Myopia Control Contacts

Myopia Control Contacts

When your child's prescription keeps climbing year after year, standard glasses and contacts only correct the blur without addressing the underlying progression. Myopia control contact lenses like MiSight 1 Day, NaturalVue, and SpecialEyes multifocals are clinically proven to slow the rate of eye growth. Orthokeratology lenses offer another proven path, reshaping the cornea overnight while also slowing progression. Together, these approaches protect your child's long-term eye health while keeping their vision sharp today.

Custom Hard Lenses

Custom Hard Lenses

When soft contacts and glasses fall short, custom hard lenses provide options designed around your exact corneal shape. Custom gas permeable (RGP) lenses are built from topography-based measurements for a precise, stable fit. Hybrid lenses like SynergEyes Duette combine a rigid center for sharp optics with a soft skirt for all-day comfort. Orthokeratology reshapes the cornea overnight so adults and children can enjoy clear, lens-free vision during the day. And for the most challenging fits, EyePrintPRO creates an impression-based lens molded directly from the surface of your eye.

Custom Soft Lenses

Custom Soft Lenses

If your prescription is too strong, your astigmatism is too high, or standard contacts simply won't work, custom soft lenses can bridge the gap. Through our SpecialEyes partnership, we fit prescriptions up to ±25.00D sphere and -8.00D cylinder, custom multifocal designs, and small-diameter pediatric lenses. For keratoconus and corneal irregularities, KeraSoft IC and NovaKone lenses deliver clear, stable vision in a soft lens format. Pinhole soft contact lenses help manage irregular iris conditions and light sensitivity. Every lens comes backed by a Guaranteed Fit Policy.

Contacts for Dry Eye

Contacts for Dry Eye

Dry, irritated eyes don't have to mean giving up on contact lenses. Scleral lenses create a smooth, hydrating layer over the cornea that keeps your eyes comfortable throughout the day. For patients with Sjogren's syndrome, ocular GVHD, post-LASIK dryness, or other chronic conditions, therapeutic scleral lenses can restore both comfort and clarity. If you've struggled with contact lens intolerance or allergic conjunctivitis, scleral lenses offer relief by shielding the corneal surface from environmental irritants.

Pediatric Contact Lenses

Pediatric Contact Lenses

Children of all ages can thrive in contact lenses with the right guidance. We fit small-diameter and high-power lenses for young children, contact lenses for infants with aphakia, and myopia control options like ortho-K and multifocal soft lenses. Whether your child needs scleral lenses for a corneal condition or their very first pair of contacts, every fitting includes hands-on training and confidence-building support so they feel comfortable from day one.

Corneal Conditions

Corneal Conditions and Complex Eyes

When the cornea is damaged, irregular, or surgically altered, standard lenses can't deliver the clarity your eyes need. We design contact lens solutions for keratoconus, pellucid marginal degeneration, corneal ectasia, post-LASIK and post-surgical complications, radial keratotomy cases, corneal dystrophies like Fuchs', corneal burns and injuries, and other complex corneal conditions. Using wavefront aberrometry, corneal tomography, and anterior segment OCT, our optometrists map the unique surface of each eye and build a lens that restores stable, high-definition vision.

Tinted and Prosthetic Lenses

Tinted and Prosthetic Lenses

Custom tinted and prosthetic lenses go well beyond cosmetics. Prosthetic lenses restore a natural appearance for scarred or unusual-looking eyes. Cosmetic tinted lenses correct mismatched eye color for a balanced, confident look. Tinted lenses for color vision deficiency enhance color discrimination in daily life. Performance tints designed for sports like golf and shooting filter specific wavelengths to sharpen contrast. And therapeutic tints reduce light sensitivity for patients recovering from concussion, traumatic brain injury, or other neurological conditions.

Is Dry Eye Behind Your Discomfort?

Burning, grittiness, watery eyes, blurred vision. Dry eye symptoms can affect everything from screen time to sleep. Our Dry Eye Screening is based on the clinically validated Ocular Surface Disease Index (OSDI) and takes just a few minutes to complete. Based on your responses, we'll also share relevant information about treatment options, from in-office procedures like IPL and TearCare to at-home strategies, so you can walk into your appointment informed and ready to have a meaningful conversation with your eye doctor.

Dizziness, Headaches, Neck Pain. Could It Be Your Eyes?

Many people live with symptoms like dizziness, headaches, anxiety, neck pain, and difficulty reading without ever connecting them to their vision. Our Binocular Vision Screening, available in both adult and pediatric versions, is based on the validated BVDQ™ and screens for a subtle vertical eye misalignment known as Vertical Heterophoria (VH), a condition that is frequently overlooked but highly treatable. Rate your symptoms, learn what they might mean, and find out if a binocular vision evaluation could be your next step.
