You can get a lens that specifically targets the computer length and reading length (mostly midrange vision with a small amount of close-range) that you can use for computer and reading, and then maybe a separate pair for far away (driving).

If the temples are long enough, someone can curve them behind your ears to make the glasses stay up. They can be tightened by bending the temple hinges a bit, or manipulating the bridge (if you have single-vision lenses).

Good luck!
