This type of lazy eye is when the eyes are not aligned so only one eye is straight when looking at something. This results in the other eye becoming “lazy” because it is not used as much to focus on things. For strabismic amblyopia, depending on the severity, vision therapy could help strengthen the eye muscles and bring both eyes straight. In extreme cases of strabismic amblyopia, eye muscle surgery may be needed to turn the eye straight.
When one eye or both eyes have a very high prescription, it can cause one or both eyes to become lazy. This is because a high prescription does not allow person not see things in focus if not corrected, and thus decreases visual stimulation. Refractive amblyopia can be treated simply by having the correct eyeglasses prescription.
This type of lazy eye is caused by the eye being physically deprived from visual stimulation from things such as cataracts, a droopy eyelid and anything else that could occlude your eye from seeing. This type of amblyopia can be treated by removing the cataract, raising the droopy eyelid or removing the occlusive factor.
