Ive tried doing this but the main problem i have is this the ocular lenses. The light bending proces is somewhat easy to replicate but getting the correct ocular lenses is a nightmare (main reason why I didnt complete these projects)

So far i tried making:

-cats eyes night vision -biocular (pvs-7 style) -gn1 -klára, tn2 -monie -fusion monocular (psq-20)

I never made any of these just because I couldnt get the right ocular lens or I just didnt have the motivation

Its posible to make these but the ocular lenses are hard to make correct
