What term describes the muscle imbalance affecting eye alignment?

The term that describes the muscle imbalance affecting eye alignment is strabismus. This condition occurs when the eyes do not properly align with each other when looking at an object. Strabismus can manifest in various forms, such as one eye looking straight ahead while the other turns inward, outward, upward, or downward. The misalignment can result in double vision or issues with depth perception, and it may require treatment to correct the alignment of the eyes, which can include glasses, vision therapy, or surgery.

Amblyopia, often known as "lazy eye," refers to a vision development disorder where an eye fails to achieve normal visual acuity, typically due to strabismus or other factors. Presbyopia is the gradual loss of the eye's ability to focus on nearby objects, commonly related to aging, while myopia refers to nearsightedness, where distant objects appear blurry. Each of these conditions involves different aspects of eye health and vision, but strabismus specifically addresses the muscle balance and alignment of the eyes.
