Eye Examination for Children: What to Expect, Who Performs It, and How It Works

The procedure itself is calmer than it seems. Below, we describe how it usually goes, the purpose of dilating drops, and the differences between the three professions a parent may encounter in this matter.

Who is Who: Ophthalmologist, Optometrist, Orthoptist

This distinction often causes the most trouble for parents, yet it can be crucial when scheduling an appointment.

Ophthalmologist is a medical doctor specializing in eye diseases. They diagnose, treat, manage pharmacotherapy, qualify for procedures, and prescribe medications. This is where a child goes when a diagnosis or treatment is needed — also when dilating drops are involved.

Optometrist focuses on examining the visual system and prescribing corrections. They measure refractive errors, assess binocular vision, and prescribe glasses and contact lenses. They do not treat eye diseases and refer patients to a doctor if pathology is suspected.

Orthoptist works on visual function — the cooperation of both eyes, eye alignment, and the visual acuity of the weaker eye. They conduct orthoptic exercises and implement procedures prescribed by a doctor, for example, in cases of strabismus or visual impairment.

In practice, these roles complement each other. Diagnosis belongs to the doctor, correction selection to the optometrist or ophthalmologist, and work on visual function to the orthoptist — usually under the supervision of the attending physician.

How the Examination Proceeds

The process depends on the child's age and the reason for the visit, but it usually includes several standard elements.

Interview. The specialist asks about the pregnancy and birth history, prematurity, family history of eye conditions, and what concerns the parent. It’s worth considering these answers in advance — specific observations from home can be more valuable than they seem.

Visual Acuity Assessment. For children who do not know letters, charts with pictures, symbols, or the letter “E” in various orientations are used. For the youngest, methods that do not require any verbal response, based on observing the child's reactions, are employed.

Refractive Error Measurement. This is done using an autorefractor — a device where the child looks at an image, and the measurement takes a few seconds and is completely painless. The result is supplemented by a test with a set of lenses.

Assessment of Eye Alignment and Binocular Vision. A series of simple tests with a flashlight, prisms, and covering one eye. For the child, this looks like a series of games and usually does not provoke resistance.

Examination of the Anterior Segment and Fundus — depending on indications, performed by the doctor.

The entire process typically lasts from twenty minutes to an hour. If drops are administered, the visit is extended by the time they take effect.

Why Use Dilation Drops

This question often arises, and it’s important to know the answer, as it explains why an examination without drops may be insufficient.

A child's eye has a very high ability to accommodate, meaning it can adjust focus by changing the shape of the lens. This ability can partially mask an existing defect — the child compensates with muscle work, resulting in a lower measurement than the actual condition. Drops temporarily disable this mechanism, allowing for a measurement of the defect as it truly is. This procedure is called cycloplegic refraction.

The application of drops may be uncomfortable for a moment but is not painful. The effect develops over several minutes, so after the drops are administered, you wait in the waiting room.

What to expect afterward: for several hours, sometimes up to a day, the child will see worse up close and will be more sensitive to light. It’s advisable to bring sunglasses and a cap with a brim and plan a calm afternoon without reading or tasks requiring close-up vision. For older children, it’s good to inform the teacher if the visit falls on a school day.

How to Prepare Your Child

A few things can genuinely ease the visit.

Be straightforward about what will happen: that the specialist will look at their eyes, show pictures, and ask them to name them. Avoid reassurances like “nothing will happen,” as the drops can be uncomfortable, and such promises undermine trust for the next visit. It’s better to say honestly, “it might sting for a moment, but then it will pass.”

Schedule the appointment for a time when the child is well-rested — the examination requires attention and cooperation. Bring a favorite toy, something to drink, and a snack for the waiting time. If the child already wears glasses, bring them along with the latest examination results.

When to Go Without Waiting for a Check-Up

As part of preventive health check-ups, a child's vision is assessed several times at different stages of development, starting from infancy and continuing through preschool and school check-ups.

However, it’s important to remember that screening is not diagnosis. Its purpose is to identify children who need further consultation, not to make a diagnosis. A correct result reduces the likelihood of a problem but does not rule it out — especially in a child who was tired or unwilling to cooperate in the office.

Regardless of check-up schedules, a consultation is advisable when:

• there is a family history of vision defects, strabismus, or visual impairment
• the child squints, tilts their head, leans in close to a book or screen
• one eye periodically “wanders” or is positioned differently than the other
• the child complains of headaches, especially after a day of close work
• they avoid reading, drawing, and puzzles, even though they previously enjoyed them
• they rub their eyes, blink excessively, or tire quickly during visual tasks

It’s worth noting that children usually do not report vision problems themselves, as they have no point of reference — the world they see is the only one they know. We discuss this in a separate article.

A visit to a pediatric ophthalmologist does not require any justification beyond parental concern.
