Final answer:
Strabismus is the misalignment of eyes, astigmatism causes uneven focus, and amblyopia results in poor vision in one eye.
Explanation:
Strabismus is the medical term for misaligned eyes, where the affected eye does not line up with the other eye. It is a condition caused by a lack of proper coordination of the eye muscles, leading to the eyes pointing in different directions.
Astigmatism is another common vision defect characterized by an uneven focus of the eye due to irregularities in the cornea or lens. It causes rays passing through different eye regions to focus at varying distances, resulting in distorted images.
Amblyopia, commonly known as lazy eye, can result from conditions like strabismus or anisometropia, leading to poor vision in one eye. If not treated early, the brain may suppress signals from the weaker eye, causing long-term vision issues.
