Anisometropia is an ocular condition where the refractive error of the two eyes differs significantly. This means one eye may be nearsighted, farsighted, or have astigmatism to a greater degree than the other, or one eye might have a refractive error while the other does not. The difference in refractive power between the eyes is the defining characteristic. When this difference is substantial enough, it can lead to issues with binocular vision, which is the brain's ability to fuse the images from both eyes into a single, three-dimensional perception.

The symptoms of anisometropia can vary depending on the severity of the refractive difference. Some individuals may experience blurred vision, eye strain, headaches, or difficulty with depth perception. In many cases, the brain may adapt by suppressing the image from the eye with the more significant refractive error, which can lead to amblyopia, or "lazy eye," if left uncorrected, particularly in children. Anisometropia can be congenital or develop later in life due to various factors.

Diagnosis is typically made through a comprehensive eye examination conducted by an optometrist or ophthalmologist. This examination involves assessing visual acuity and measuring the refractive error in each eye. Treatment strategies for anisometropia aim to equalize the refractive power between the two eyes to allow for clear and comfortable binocular vision. This often involves corrective lenses, such as eyeglasses or contact lenses, with different prescriptions for each eye. In some instances, refractive surgery may be considered for adults. Early detection and management, especially in children, are crucial to prevent long-term visual development issues.
