It has been pointed out that the penalization of one eye by means of patching or atropine drops does not provide the conditions that are necessary in order to develop or improve binocular vision. Recently, efforts have been made to propose alternative treatments of amblyopia that do allow for the improvement of binocular sight, for example using binasal occlusion or partially frosted spectacles[1] in place of any eye patch, using alternating occlusion goggles or using methods of perceptual learning based on video games or virtual reality games for enhancing binocular vision.
