ABSTRACT:
The present invention is directed towards adhering a contact lens button on a fixture for use in shaping, forming and/or otherwise configuring a contact lens. For example, in accordance with one exemplary embodiments of the present invention, a combination of adhesive materials are used to adhere the lens to the fixture. For example, a first layer of water soluble adhesive is placed on the lens button. A second layer of non-water soluble adhesive is then placed on the first layer, and the button is mounted to the fixture. Both layers are subsequently removable by placing the button in a water bath, dissolving the water soluble layer and likewise separating the water insoluble layer.
