Overview
Children use vision to learn about faces, movement, language, and the world around them. Vision develops from birth through childhood, so problems can appear at different ages. Some issues are mild and easy to correct, while others can affect visual development if they are not found early.
Key Symptoms
Possible signs of a vision problem include squinting, tilting the head, covering one eye, frequent eye rubbing, headaches, or complaints of blurry or double vision. In babies and younger children, warning signs may include poor eye contact, eyes that do not seem to work together, unusual sensitivity to light, or delayed tracking of objects. Teachers or caregivers may notice trouble reading, losing place on a page, or avoiding close work.
Causes and Risk Factors
Common causes include refractive errors such as nearsightedness, farsightedness, and astigmatism. Other causes include lazy eye (amblyopia), crossed eyes (strabismus), eye injuries, infections, and some birth or genetic conditions. A family history of eye problems, premature birth, developmental conditions, and certain medical illnesses can increase risk.
Who Is Affected
Vision problems can affect babies, children, and teenagers in any country or setting. Some conditions are present at birth, while others become more noticeable when a child starts school or spends more time reading. Children who cannot explain what they see may be at higher risk of a problem being missed.
Prevention
Not all vision problems can be prevented, but routine screening helps find issues early. Protect children’s eyes from injury during sports and play, and keep sharp objects and chemicals out of reach. Encourage outdoor time, good reading habits, and breaks from long periods of near work or screen use.
Diagnosis and Tests
Health professionals may check how the eyes look and move, how well a child tracks objects, and whether each eye sees clearly. Vision screening may be done in clinics, schools, or community programs, and some children need a full eye examination by an eye specialist. Younger children may be tested using pictures, shapes, lights, or special devices instead of letter charts.
Treatment Categories
Treatment depends on the cause and may include glasses, vision monitoring, patching or other therapy for amblyopia, or treatment for strabismus. Some children need care for infection, injury, or another medical condition affecting the eyes. Follow-up is important because a child’s eyes and vision can change as they grow.
When to Seek Medical Care
Arrange a medical or eye assessment if a child fails a vision screening, complains of blurry vision, has frequent headaches with visual tasks, or shows signs such as squinting or one eye turning in or out. Seek care if there is redness that does not improve, discharge, pain, light sensitivity, or concern after an eye injury. Early evaluation matters because some conditions can affect visual development even when a child seems otherwise well.
When It May Be an Emergency
Get urgent medical help for sudden vision loss, severe eye pain, a chemical splash in the eye, a penetrating injury, major trauma, new unequal pupils, or swelling with fever around the eye. Urgent care is also needed if a baby or child has a white pupil in photos or in normal light, or if one or both eyes suddenly start crossing. These signs can point to serious eye or nerve problems.
