A simple solution we use at our centers is to apply a translucent patching material which originally invented to reduce vision in the patched eyes of amblyopic children. It allows some light and motion to reach the eye but adequately blocks the double vision in most situations. Notice the improvement of the appearance of this young lady with a traumatic third nerve paralysis. Not the top right picture which shows the right eye drifting out and down. At ten to twenty feet the patch is nearly invisible to others.
Patients feel better about appearing in public.
Here we applied a translucent patching material to the right lens of her eyewear. It can be applied in minutes, often to the existing eyewear. In some cases with specific areas of gaze in which double vision occurs, it may be possible to patch only a sector or spot. See our section on sector and spot patching . Notice that while some vision may pass through the patch, the awareness of the image is greatly reduced.
