Signs and symptoms of lazy eye include:
- An eye that wanders inward or outward
- Eyes that may not appear to work together
- Poor depth perception
Although lazy eye usually affects just one eye, it's possible for both eyes to be affected. Sometimes lazy eye is not evident without an eye exam.
When to see a doctor
Primary care doctors often check vision as a routine part of well-child checkups — especially if there's a family history of crossed eyes, childhood cataracts or other eye conditions. If you notice your child's eye wandering at any time beyond the first few weeks of life, consult your child's doctor.
Depending on the circumstances, your doctor may refer your child to a specialist in eye conditions (ophthalmologist or optometrist). For all children, a complete eye exam is recommended between ages 3 and 5.
