Overview
Common causes include a difference in glasses power between the eyes, a squint, or anything blocking clear vision early in life (like a pediatric cataract). The eye itself may look completely normal — which is why lazy eye is often missed without an examination.
Treatment typically combines the correct glasses with patching (or penalising) the stronger eye so the weaker one is trained to work. Results are best when treatment starts young, though older children can still benefit in selected cases.

Common Symptoms
- Often no obvious complaint — found on screening
- One eye that turns in or out
- Poor depth perception
- Covering one eye to see
- Bumping into objects on one side
Possible Causes
- Unequal refractive error between the eyes
- Squint (strabismus)
- Visual deprivation (e.g., pediatric cataract, droopy eyelid)
Risk Factors
- Family history of squint or lazy eye
- Prematurity
- Developmental delay
When to Consult
As early as possible — if a screening, a photo or a teacher raises suspicion, do not wait. Earlier treatment generally works better.
Evaluation Process
- Age-appropriate vision testing of each eye
- Cycloplegic refraction
- Alignment assessment
- Eye health examination to find the cause
Available Management Options
- Correct glasses worn full-time
- Patching or atropine penalisation of the stronger eye
- Treatment of the underlying cause (e.g., squint or cataract care)
- Close follow-up to track improvement
The right option for you depends on examination findings and will be discussed before any treatment.
Follow-Up Information
Amblyopia therapy needs regular reviews to adjust patching and glasses, and to guard against recurrence as the child grows.
