I have poor vision myself and wear glasses but I live alone in a medium-sized apartment. I keep my glasses nearby but I would still grab the gun probably before my glasses. In some ways I have felt that smaller dwellings can be more cozy and safer than huge houses with huge lots. Sure, if you can afford those you can also have a good alarm system, a big fence, cameras, and all kinds of goodies to keep you safe. However, the more you have the more there is to protect. With a huge house, huge lot, and multiple floors and rooms, someone could be in your house and you wouldn't even know it. There would be so many places you'd have to look to find a potential intruder and so many places they could hide, that it would actually hinder your safety. Then if your house is also full of your friends and family, you have to hunt them down to figure out where they are. I've always believed, keep it simple.
