(Edit: TruFocals are now called Superfocus) Okay, I haven't worn my Trufocals out of the house since the day I got them. I've worn them in the house plenty. I'm just sissy to wear them in public, I guess.
Did I mention that they look a tad different? As in, funny?
Before I got my Trufocals, I wore my progressive (no-line bifocal) lens glasses when shopping, visiting museums, etc. They were extremely useful when I was taking classes at a local university and I had to look at the board and then down at my notebook to take notes, but my distance vision isn't so bad that I need to wear them during all waking hours. At home I wore my reading glasses when reading, at the computer, knitting, etc.
So I have fallen into the same pattern with my Trufocals, except for the fact that I am a little embarrassed to wear them out and about.
I haven't taken any university classes lately (I had been working on a 2nd degree part time), but I'm not sure how the Trufocals would work in that situation. Having to adjust the focus between the board and your notebook might present a problem. The board is sometimes pretty far away in the big lecture halls, so it would be hard to find a focus that would work for the board and your notebook at the same time.
And, here's the thing - you can focus so well with the Trufocals that it really is bothersome when something isn't in super sharp focus, so finding a mid-focus for the board and the notebook for the duration of a lecture might actually make your eyes feel bad, or maybe give you one of those vision headaches.
But again, I haven't been in the classroom lately, so all of that is conjecture. My husband teaches at the local university, maybe he'd let me sit in on one of his classes so that I could try it out. I'll have to see about that.
One other thing that has cropped up in my "what if?" files - what if your hands were really goopy, or otherwise occupied and you found that you needed to adjust focus? This came up while carving my Halloween pumpkin. I was wearing my Trufocals and rejoicing in being able to see the tiny marks I had made on the pumpkin which formed the outline of the pattern I was attempting to cut out. But my hands were goopy with pumpkin goo and, although I didn't need to change focus while carving, I thought about what a pain it would be to have to clean my hands first and then focus, so as not to slime up my glasses and the focusing mechanism, if the need to change focus arose.
But here is another positive. One of my cats had an altercation with another cat and received an injury to her eye. I was able to focus in and really see what was going on with her eye. It's nice to be able to see little things up close and in focus (her eye will be fine, but her third eyelid will be forever ragged-looking, so says the vet).
I have to toughen up and wear the things out shopping again. Wow. I didn't know I was so vain. Gotta get over that.
