The disclosure relates to a machine for aligning and attaching partly-worked lens blanks to a block so that the remainder of the blank can be machined. The machine comprises a vee-shaped holder for supporting the block with it axis vertical above a moveable table on which the lens blank is supported. The moveable table is freely moveable in any direction in a horizontal plane and the machine includes means for bringing the block and partly-worked lens into contact and achieving alignment of the axes of the block and lens blank by permitting the lens blank to move in any direction in a horizontal plane. A film of liquid adhesive is provided between the surface of the lens blank and the block which acts both as a lubricant and as a bonding agent when correct alignment has been achieved.
