Hi Julia! Could you get a screenshot of your shader editor with the node setup? Off the top of my head I can't think of what the issue might be but seeing your node setup might help!
Hi Julia jjuliadu ,
My guess would be, that there is nothing to see through the 'glass'. The inside of the binoculars is mainly dark (hardly any light reeaches there). In the screen-right glass, you can see some light through the back glass. If you are using an HDRI for the Lighting, and make sure the Roughness of the glass Material is quite low, you should see some reflections in them.
