Multicomponent optical device having a space

An optical device comprising:

• a first posterior component comprising a gas-permeable optical material and an anterior surface;
• a posterior support component;
• an anterior component comprising a posterior surface;
• an anterior skirt comprising the gas-permeable optical material;
• and
• a primary space between the posterior surface of the anterior component and the anterior surface of the first posterior component, wherein the primary space is configured to permit diffusion of a gas from a perimeter of the primary space through the primary space and across the anterior surface of the first posterior component, further comprising a porous spacer ring in the primary space.

A multicomponent optical device prepared by a process comprising:

• mating a gas-permeable first device component to a second device component, wherein the first device component is inserted into a receiving portion of the second device component;
• bonding the first device component to the second device component;
• mating a third device component to the first device component, wherein following mating of the third device component to the first device component, a primary space remains between an anterior surface of the first device component and a posterior surface of the third device component;
• and
• bonding the third device component to the first device component.
