<unk> , also referred to as electronic rapid alternate occlusion, is an approach to amblyopia and to intermittent central suppression in vision therapy, in which electronic devices such as programmable shutter glasses or goggles are used to block the field of view of one eye in rapid alternation. When performing<unk> , the person wears the occlusion goggles continuously for several hours while performing regular everyday activities. Wearing the device encourages or forces the<unk>  use of both eyes, similar to eye patching, but rapidly<unk>  in time. The aim is to circumvent the tendency to suppress the field of view of the weaker eye and to train the capacity for binocular vision. Traditionally, eye patches are used to block the field of view of one eye. Strabismic or amblyopic children are often required to wear an eye patch for hours or days. The use of the patch generally alternates on a daily or weekly basis between the two eyes, with a long time duration for the patching of the stronger eye and a shorter time duration, if any, for the patching of the weaker eye. In contrast to eye patching,<unk>  with occlusion goggles allows to use rapid rates of alternation. __TOC__
