It's not getting worse, his eyesight most likely became worse from reading a lot, doing work, etc. Also, their eyesight only worsens IF they're a failed experiment. Kaneki was a human before the surgery of course because he could eat human food lmao. it's impossible for him to have been a ghoul before the experiment before the surgery since his sense of taste completely changes right after. We never seen Kaneki's father because he's probably just a normal person or was/is currently involved with something. He got crazy strong because he has Rize's kagune which is strong and has powerful regeneration. He learned to fight when training with Yomo and Touka, but after accepting his ghoul side, his S rated kagune and Rize's personality took over. He was weak in the past because he didn't accept his ghoul side, but now that he has, he is strong. He was successful because he just happened to be. Remember, the chances are very low and he's the only successful one who's mentality is under control since the final fight with Arima.
