Occasionally I like to take a shower / bath in the dark. In a way it is therapeutic to my mood. In another way it reminds me that even if I lost my eyesight I would still be able to take care of myself, to dress myself and get ready for the day. Since I haven't been programming in a while an inability to see a computer screen doesn't scare me as much as it once did. I would definitely have to find another career, or have someone dictate changes and existing functionality (or find a way for programming concepts to be relayed verbally), but it wouldn't be the end of the world.
