I'm pretty confused about your comment and all the replies. Do you all not have lights? I can see my keyboard just fine without backlighting. Not wanting backlighting has nothing to do with whether I need to look at my keyboard or not. I just think it's ugly (which is just a preference, totally fine for people to like it).
Yes, controlling your lighting situation is certainly a good solution. For me, even though I don't compute in the dark I do keep the ambient light pretty dim. I get sick of squinting at the keys.
