The world need not know what is within!
A non-seeing eye or an eye that has been removed can be easily concealed with an artificial eye or prosthesis.
Removal of the eye could be required for numerous causes ranging from cancers of the eye to a shrunken eye after an eye injury. Enucleation and Evisceration are procedures to remove the eye. An implant or a ball is placed in the place of the eye. This is followed by making a prosthesis that looks very similar to the other eye. Some amount of movements with the movement of the other eye can be obtained. Eye-opening and closure can also be achieved. Thus even a non-seeing eye or an empty socket can be made to look near normal
