Amblyopia refers to poor vision in an eye when all other causes are discounted. Often it is confused with a squint, but amblyopia can occur even if the eyes are straight.
In amblyopia, it is important to check if glasses will sort the problem out before using occlusion. This is called Refractive Adaptation. This can take 4 months to work as unlike adults it takes some time for the brain to adapt to glasses. We only treat with Occlusion when we have the best vision from glasses.
This is also useful as the child will be able to see something rather than very little in the bad eye with occlusion and may want to continue rather than fighting with the parents.
