Abstract
An electronic device may have optical components that each have first and second transparent layers such as first and second glass layers. The glass layers may have outer surfaces that face away from each other and inner surfaces that face towards each other. A polymer layer is formed between the inner surfaces of the glass layers. Along the periphery of each optical component, a hermetic seal is formed to protect the polymer material of the polymer layer. The seal may include one or more metal layers that are coupled to the first and second glass layers. Alternatively or additionally, the seal may include an internal seal, such as a metal foil layer that extends between the first and second glass layers, within the optical component to reduce the width of the optical component.
