Amblyopia, commonly known as lazy eye, is the leading cause of visual impairment in children worldwide, yet many parents in Singapore fail to recognise its early signs. Unlike common refractive errors, this condition is not always obvious—your child may not even realise they are experiencing blurred vision. Left untreated, amblyopia can lead to permanent vision loss, affecting academic performance and daily activities. But how can you spot it, and what can be done?
What Is Amblyopia?
Amblyopia occurs when one eye develops weaker vision because the brain favours the other, causing the weaker eye to lose function over time. This often results from:
- Strabismus (crossed eyes) – When the eyes are misaligned, the brain suppresses input from one eye.
- Refractive differences – A significant difference in prescription between the two eyes can cause one to dominate, leading to neglect of the weaker eye.
- Deprivation amblyopia – Conditions like congenital cataracts or droopy eyelids (ptosis) can block vision and prevent normal eye development.
Without early intervention, amblyopia can persist into adulthood, reducing depth perception, impairing coordination, and increasing the risk of accidents.
How Common Is Amblyopia in Singapore?
Amblyopia is more prevalent than many realise. Studies suggest that up to 4% of children in Singapore suffer from some form of amblyopia. With a high rate of myopia in Singaporean children—83% of 18-year-olds are myopic, according to the Singapore National Eye Centre—the risk of undiagnosed amblyopia is even greater. Early detection is crucial, particularly in densely populated areas like Tampines and Jurong, where access to healthcare services can vary.
Research also highlights that children diagnosed before the age of five have a much higher success rate with treatment, reinforcing the need for early intervention.
Signs Your Child May Have Amblyopia
Most children with amblyopia do not complain about vision problems because they unconsciously rely on their stronger eye. However, there are subtle signs parents should watch for:
- Squinting or closing one eye to see clearly
- Frequent head tilting
- Difficulty with depth perception (trouble catching balls, frequent tripping)
- Eyes that appear misaligned or do not move together
- Complaints of headaches or eye strain
- Struggling with reading or recognising letters and numbers
- Avoiding activities that require sharp vision, such as puzzles or colouring
If you notice any of these symptoms, a comprehensive eye exam is essential. Amblyopia is not something that will resolve on its own—it requires professional diagnosis and treatment.
Can Amblyopia Be Treated?
The good news? Amblyopia is highly treatable if caught early. Treatment options include:
- Patching therapy – Covering the stronger eye forces the weaker eye to work harder and develop better vision.
- Atropine drops – Used to blur vision in the stronger eye, encouraging use of the weaker eye.
- Corrective lenses – Glasses can correct refractive errors and improve vision in both eyes.
- Vision therapy – Eye exercises and interactive activities strengthen eye coordination and depth perception.
Studies show that treatment is most effective before the age of seven, though improvements can still be made in older children and even adults. Amblyopia therapy can improve vision by up to 60% when started early, according to research conducted in Singapore. However, older children may require more intensive intervention, and success rates decline significantly after adolescence.
Early Eye Screening: The Key to Preventing Vision Loss
Singapore’s Ministry of Health recommends regular vision screenings for young children. Experts advise eye checks at six months, three years, and before starting primary school. Parents should take advantage of these screenings at local polyclinics, schools, or private clinics in areas like Bukit Batok and Punggol, ensuring early detection and intervention.
Regular eye screenings are particularly important in a digital age where excessive screen time is linked to worsening vision issues. Singaporean children spend an average of 6.5 hours per day on screens, increasing the likelihood of undiagnosed visual impairments, including amblyopia.
Take Action Now
Amblyopia is a silent threat to your child’s vision, but with early screening and treatment, it is entirely manageable. Don’t wait until it’s too late—schedule an eye exam today and give your child the gift of clear sight. Remember, the key to overcoming amblyopia lies in early intervention, regular screenings, and consistent treatment.
