Seen in around 1 in 50 children at around the age of 4 during regular checks, amblyopia or lazy eye means that one of your child’s eyes is weaker than the other. This causes them to rely more on their ‘good’ eye.
Glasses are typically prescribed to correct the vision in the weaker eye and, in most cases, no further treatment will be required. However, if the weak eye does not respond fully, then a patch can be worn over the good eye for some of the day to encourage the weaker eye to work properly. This kind of treatment is usually effective, but it can take a while to show results.
