The article describes a technique for sensing infrared light, turning it into an electric current. It's not possible to do that and display an image on a contact lens that we could actually focus on (you can't focus on something that's right on your eye).
The only way to make a contact lens that would allow somebody to see infrared light would be to have a lens made out of a material such that when it receives an infrared photon, it absorbs that photon and emits a visible-light photon traveling in the same direction. That's very much not going to be possible with a technology built for sensing in this manner. The use of this tech would basically be lighter-weight infrared goggles and other sensors.
