Without even visiting the article I can say with full confidence these contact lenses will not be opaque.
Comment on Infrared contact lenses let you see in the dark

Yes, this includes ultraviolet light.
Why? Does it also include x-rays? That’s only one step further on the electromagnetic spectrum. Seems arbitrary to stop at ultraviolet waves! Does that mean thin sheets of steel aren’t opaque? Or is it the term “opaque”, without any modifiers attached, colloquially used to describe whether something permits visible light through?
For the record, they’re not opaque. The article actually says they work better if you close your eyes.

Or with cosmic rays, not sure anything would be opaque.

We already can detect direction of infrared radiation, it’s called being warm on one side but not the other. Technically also possible by, say, lying half-way under a blanket and half-way not, but sensory integration takes care of the ambiguity.

No I did not know that. Interesting.
