I’m wearing my first-ever pair of bifocals now. Well, not right this minute. I’m nearsighted, so I don’t need corrective lenses to see a computer screen that’s right in front of my face. There are times, though, when I have to look at someone else’s computer screen and it gets weird because to get close enough to read it, I have to invade their personal space. Some people don’t mind so much, but some people do.

There are also times when I’d like to be able to read the various dials and readouts on the dashboard of my car. Some readouts I can look at and know what they’re telling me without actually reading them; the speedometer, for instance. I know when it’s pointing at “60” instead of “50.” But sometimes I want to know the name of the song on the radio, or read the map display, and to do that I would have to tip my head way back and peep under the lenses of my old prescription.

I don’t have to do that now, but it’s a bit of a struggle overcoming the muscle memory. I keep peeping under the lenses when all I have to do is dip my eyes to look through the lower half of my new lenses.
