Anisometropia Introduction Anisometropia is an eye condition in which the refractive power of the eyes is unequal. Due to this difference in refractive power, the vision of one eye differs from the other; for example, one eye may be nearsighted (myopic) and the other farsighted (hyperopic). When the total refraction of both eyes is unequal, this condition is called anisometropia. This inequality can cause various visual disturbances and significantly affect the quality of life. A person with anisometropia will see a smaller image with one eye and a larger image with the other, often resulting in overall blurred vision. Although anisometropia can be present at birth, it is especially important in children because it can lead to "lazy eye" (amblyopia), where the brain ignores the image from the weaker eye, potentially causing permanent vision impairment. Main Types of Anisometropia: Simple anisometropia - When only one eye is affected, one eye may have normal vision (emmetropi...
