Without even visiting the article I can say with full confidence these contact lenses will not be opaque.

EDIT: We really don’t have to go beyond the conceptual stage.

• transparent: clear, all light goes through
• translucent: clouded, some light goes through
• opaque: wall, no light goes through

Yes, this includes ultraviolet light. If a contact lens is opaque, it blocks all light from passing through the eye’s lens and cornea. It will never reach the retina to even be recognized as on or off! No opaque contact lens will ever be used. Please tell me if I’m wrong…
