ABSTRACT:
An accessory for holding a contact lens includes a concave element that is place adjacent to a user's cornea or adjacent to a contact lens on that user's cornea and a fluid circuit that connects an air passage in that concave element to the interior of a flexible hollow ball. Flexing the ball causes air to move out of the air passage to move a contact lens from the concave element onto a user's cornea, and release of a distorted ball sucks air into the air passage to move a contact lens off of a user's cornea onto the concave element. Guiding elements include mirrors and support arms.
