The invention relates to a method for applying a joint (2, 102) onto a plate (3), in particular a plate having shape defects. An edge of interest is defined on a portion of the plate (3) onto which the joint (2, 102) is intended to be applied. The plate (3) is then placed on a tool (4, 104) comprising a supporting element (5, 105) made of solid material and a supporting element (6, 106) made of flexible material, in such a way that the edge of interest rests on a portion of the supporting element made of flexible material. While the joint is applied onto the edge of interest, the plate is maintained in a predetermined reference position and the element made of flexible material is pushed against the plate, perpendicularly to an outer surface of the element made of flexible material, the outer surface being opposite to the surface on which the edge of interest rests.

Apparatus and methods are described including adhering a first lens to a second lens such as to form a combined lens having a given optical design, by placing the first lens and the second lens in respective first and second pressure chambers with an adhesive layer disposed between the first lens and the second lens, bringing a convex surface of the first lens into contact with the adhesive layer, and bringing a concave surface of the second lens into contact with the adhesive layer. Other applications are also described.

Apparatus and methods are described including an additional lens (24) made from an amorphous viscoelastic material and having an optical design. A curvature of the additional lens (24) is changed such as to conform with a curvature of abase eyeglasses lens (22), without causing a loss of the optical design of the additional lens (24), by heating the additional lens (24) to a temperature at which a Tan Delta of the amorphous viscoelastic material is between 0.2 and 0.8, and shaping the additional lens (24). Subsequently, the additional lens (24) is adhered to the base eyeglasses lens (22). The optical design of the additional lens (24) is such that, upon being adhered to the base eyeglasses lens (22), the adhered base eyeglasses lens (22) and the additional lens (24) provide a combined lens (20) having a desired optical prescription. Other applications are also described.
