Lazy eye (amblyopia) is a condition that starts in childhood in which the brain is unable to properly register the sight from one eye due to a problem in how the brain and the eye work together
Lazy eye can affect a person’s vision, causing poor vision in one eye. The brain relies more on the stronger eye, causing vision in the weaker eye to worsen.
Symptoms of lazy eye include:
- Double vision
- Problems with depth perception
- Appearing to struggle to see clearly
- Shutting one eye
- Tilting the head
These issues can be subtle and parents or caregivers may not notice them. Lazy eye is frequently diagnosed through routine vision screening during a doctor's check-up or at school.
What Causes Lazy Eye?
Causes of lazy eye include:
- Crossed eyes (strabismus)
- Refractive errors
- Cataracts (uncommon in children)
Risk factors for developing lazy eye include:
What Is the Treatment for Lazy Eye?
Early treatment to fix lazy eye and prevent long-term vision problems includes:
- Training the weaker eye by making it work harder so it can get stronger
- An eye patch worn over the stronger eye so that eye can't see
- Eye drops to put in the stronger eye to blur vision in that eye
- Glasses or contact lenses
- For nearsightedness
- For farsightedness
- For astigmatism
- To treat cataracts
- To fix droopy eyelids
- To strengthen muscles if due to crossed eyes
Vision may begin to improve within a few weeks but it tends to take months for the best results. Children may need to continue to use the treatments on occasion to prevent the lazy eye from returning.
