Yorkies and eyesight in the later years.

My main man Louis is losing his eyesight… to be honest it is killing me. I can throw a treat 4 feet away and he struggles to find it. I guess it’s cataracts… but sometimes he can see the wife from 50 yards or so. I can tell from his reactions. I asked the vet and he just said they lose vision like this. He is 14 but pretty healthy otherwise. We still go for walks and stuff but I carry him if the grass tall… he will just stand there and not follow me now. Any advice or options are appriciated. First pic is the week we got him and next was yesterday.
