Abstract
Methods and apparatus for making lens assemblies that can be placed on an eye of a person and that include at least one component are described. Generally, a first lens member (100) and a second lens member (200) are formed. The second lens member (200) is transferred to a compliant stage (210). At least one component is placed in contact with one of the lens members (100, 200). The second lens member (200) is placed in contact with the first lens member (100) such that the compliant stage (210) can provide compression to the first and second lens members (100, 200). The second lens member (200) and the first lens member (100) are coupled together to form a lens assembly (10) with the at least one component located between the two lens members (100, 200).
Claims16
A method of making a lens assembly, the lens assembly comprising a first lens member, a second lens member and a component located therebetween, the method comprising:
- forming a first lens member;
- forming a second lens member;
- transferring the first lens member to a compliant stage;
- placing at least one component on the first lens member or the second lens member;
- while the first lens member is located on the compliant stage, bringing the first lens member and the second lens member into contact with each other such that the at least one component is located between the first lens member and the second lens member, the compliant stage providing compression to the first lens member and the second lens member;
- and
- coupling the first lens member and the second lens member together to form the lens assembly, wherein
- the lens assembly is a contact lens configured to be placed on an eye of a person.
An apparatus for making a lens assembly, the lens assembly comprising a first lens member and a second lens member and at least one component located therebetween, the apparatus comprising:
- a first stage support comprising at least one compliant stage comprising a convex surface configured to retain a first lens member;
- a second support;
- and
- a support coupler configured to retain the first stage support and the second support together so that a first lens member located on said at least one compliant stage of the first stage support can be placed in contact with a second lens member located on the second support such that each compliant stage provides compression to the first lens member and the second lens member with the at least one component positioned between the first lens member and the second lens member, wherein the compliant stage has a surface topography selected to provide coupling between the lens members only at selected locations on their surface.
