In my experience, farsighted people tend to be very casual with their glasses, whereas us nearsighted folks protect them carefully.

My theory is that being nearsighted, I can see my glasses - every smudge or speck of dirt is immediately visible to me because it's not too far from my focal distance. For farsighted people, the glasses on their face are so far out of focus that those things simply disappear.

If I lay down with my glasses and they rub against my face or the pillow, I know they're going to get smudged and I'll suffer eyestrain until I find a lens cloth and carefully clean them. Any nick in the lens will drive me crazy until I can get it replaced. As such, I am very protective of them - any time I lay down I'm fold them closed and lay them face-up on the headboard so they won't need more than quickly brushing off a few specks of dust. I also buy very thin, light frames because I can see them pretty clearly in my peripheral vision.

The people I've known who are farsighted (including my husband), are oblivious to anything on the glass. He'll just roll around in bed with them, and maybe once a week ask me to clean them for him. We have to get him heavier frames because the lightweight ones would be a mangled mess in a month.

So yeah, I'm guessing you have the latter experience... Sturdy frames and you aren't too bothered by some smudges when you get up.
