What is the condition in which a child wearing an eye patch is most likely being treated for?

Strabismus
Astigmatism
Presbyopia
Amblyopia

The correct answer is: Amblyopia

Amblyopia is a condition also known as "lazy eye" where one eye has weaker vision than the other. It is commonly treated with the use of an eye patch over the strong eye in order to strengthen the weak eye. This treatment method is called "occlusion therapy". This is different from strabismus (option A), which is a condition where the eyes are misaligned, making it difficult to focus on one object. While strabismus can potentially be treated with surgery, amblyopia does not usually require surgery. Option B (astigmatism) and C (presbyopia) both refer to refractive errors, where the shape of the eye affects how light is focused, but neither of these conditions require the use of an eye patch for treatment.
