Aniseikonia is a condition in which the image of an object formed in the right-eye differs significantly (in size or shape) from the image of the same object formed in the left-eye.
When the images of the same object on the right- and left- eyes appear to be too different, e.g. in size, diplopia, disorientation, eyestrain, headache, and dizziness and balance disorders can result.
In many cases aniseikonia can be treated with the use of corrective lenses, such as spectacles or contact lenses which must be prescribed specifically for each patient according to his or hers needs.
