Definition: Anisometropia refers to a condition where an object appears as two separate images, one of it's straight side and another inverted or distorted. It is caused by the misalignment of the eye's retina in the field of vision, leading to differing visual experiences for each eye. The definition typically includes problems with focusing on distant objects, seeing colors differently from one eye compared to the other, experiencing light sensitivity issues, and difficulty seeing things at night.
