Which term describes unequal vision in the two eyes?

The term that describes unequal vision in the two eyes is heteropsia. This condition refers specifically to a significant difference in visual acuity between the two eyes, which can result from a variety of underlying causes. It is important to recognize that this term highlights the imbalance in visual perception, making it distinct from other ocular conditions.

In contrast, strabismus primarily refers to misalignment of the eyes, where one eye may turn inwards, outwards, upwards, or downwards. While strabismus can be associated with visual issues like double vision or amblyopia, it does not specifically refer to the difference in visual acuity between the eyes.

Myopia and hyperopia, on the other hand, are types of refractive errors related to how light is focused in the eye. Myopia, or nearsightedness, indicates that distant objects appear blurry, while hyperopia, or farsightedness, indicates that nearby objects may appear blurry. These conditions affect vision quality but do not inherently describe a discrepancy in the visual acuity between the two eyes.

Understanding heteropsia is crucial for addressing and managing visual disparities effectively, which can significantly impact daily life and overall visual health.
