With all this talk about finding items and making pretenders go blind (a very evil thing btw

), a few questions have popped into my mind:
1. If a commander is disintegrated, will he/she drop his/her items, or do they become dust aswell?
2. Can pretenders that don't appear to have eyes (ex: Oracle, Fountain of Blood, etc.) actually go blind?
3. Is it possible to heal lost eyes?
4. Is chlorine actually good for your eyesight (I don't think so, but I'm being told that it is by my friends)?
