I'm always eager for new technology and inventions that improve my life. So when I discovered "TruFocals", now identified as "SuperFocus" which are the newest concept in eyeglasses I had to get a pair.
Reading about them is not the same as using them. It was difficult to break old habits like looking over the upper rim of my reading glasses to see things in the distance. I did
this repeatedly for the first 24 to 48 hours with the SuperFocus glasses. Finally, I began to regularly remember to reach up to move the slider to refocus instead. But here again I ran into trouble, because I wanted to put my thumb on the bottom of the glasses rim while placing my index finger on the slider on top of the bridge. This was awkward and tended to move the glasses around. It was not natural for me to put my thumb on the bottom of the bridge. Once I figured this out and adapted to thumb on bottom of bridge and index finger on top on slider was the way to go, things got better.
I've been using SuperFocus for about two weeks now and the automatic refocus reflex has started to be a natural part of my routine in looking around. It's great to have anything I want to see in perfect focus. However, in some situations refocusing can be difficult to impossible; when doing tasks where both hands are dedicated to holding moving things or when both hands are smeared with something like dirt in the garden or bread mix, etc. In these cases I have to anticipate and set a "compromise" focus distance that will serve me till my "refocus finger" is once again available. I'm not good yet at anticipating this circumstance every time.
These glasses have really changed my life for watching TV at "sort of long distance" and computer screen at "sort of short distance". These distances were my nemesis and always drove me crazy because reading glasses didn't help and my far sighted eyes were just slightly out of focus for across-the-room.
My trivial, only negative is because of my rather large head. These small diameter rims make me look like an elderly "Harry Potter". And my friends always look at me a little strangely when they first see me in these. I quickly explain why I'm making this new fashion statement and the crisis passes. Anyway the improvements for me are worth the adaptations and change in my appearance!
The actual way the glasses work is a mystery to me even though I've looked closely AT the mechanism as I move the focus slider. BUT. . .HEY. . .THEY WORK!
