iBalls have an initial cost of $999 each and require a $59/month subscription. Both natural eyes must be removed prior to installation — but if you have limited funds, you can start with just one iBall, then use the optional iPatch ($49) to cover the vacant socket. Those who default on their iBalls subscription will lose all functionality, including basic vision. However, in these cases, Apple will provide iBraille training at no additional cost.
