What term describes a tendency for the eye to turn inward?

The term that describes a tendency for the eye to turn inward is known as esophoria. In this condition, one eye may drift towards the nose when the individual is not focusing on an object, leading to an inward deviation. Esophoria is a form of heterophoria, which refers to a latent strabismus that can become apparent under certain conditions, such as fatigue or stress.

Understanding esophoria is important in the field of optometry because it can impact a person's binocular vision and overall visual comfort. When the eyes do not work together effectively, it can lead to visual disturbances or difficulties in tasks that require depth perception. Early detection and management of esophoria can help prevent secondary issues, such as amblyopia or visual fatigue.
