One thing is to get your doctor to prescribe a pair of "astronomy

The difference between these and your regular prescription is that these
are
focused at infinity (instead of some closer point as is done normally).
That's interesting, I had no idea that could even be done. Do you need
a *ginormous* exam room for that?
Nope g... you just have to ask for them to be focused at infinity. It's
especially helpful if you have astigmatism.
