I have worn glasses full-time since I was 10 years old. In my late 30s, I had trouble with close vision and tried progressive lenses, which I absolutely hated, and went with traditional bifocals, and I was quite happy with them for many years.(I think the trick with bifocals is to have larger lenses, so both the reading and distant lenses are large, but unfortunately, the current fashion for glasses is for shorter lenses from top to bottom). Then in my 50s, I was having problems seeing mid-range – like when using a computer. So I went with trifocals (very little adjustment from bifocals) and was happy with them for years. I am currently 64, and about a year ago once again I started having problems with my vision. If something wasn’t just the “perfect” distance for each of the three lenses of my trifocals, I couldn’t see it clearly. So I tried the Superfocus glasses, and I like them a lot. But it is important to accept that once single focus lenses no longer work for you, there are no perfect solutions. Everything at that point is an issue of advantages and disadvantages.
Honestly, I wish trifocals still worked for me. They were a lot easier to use (and cheaper). The use of bi/trifocals becomes second nature pretty quickly and they require no use of the hands to change the focus (just a slight tilt of the head). And yes, I did get some neck strain I suppose, but it wasn’t too bad. So, unlike many people, I didn’t go with the Superfocus glasses to eliminate bifocals, trifocals, or progressive lenses. I went with them out of necessity to see clearly at all distances. And to that end, they work like a charm. They really do. And the hand motion to adjust them does become quite second nature fairly quickly. BUT – it requires the use of a hand to change the focus. So if you are carrying something with both hands, or your hands have something on them (dirt from gardening, food from cooking, etc.) it is a bit of a challenge. I give lectures and use notes and I also like to be able to see the audience clearly (in other words, I am constantly switching from midrange to distant, over and over again) and must constantly adjust the Superfocus glasses. So for me, that is the biggest drawback with them. But I will also readily admit I really do like having a full lens (vs. areas of the lens like with trifocals) for any distance. That is super nice.
For someone like me, they work better than anything else, which is why I like them. They aren’t perfect, but as I said, there are no perfect solutions for multi-focus glasses. I would suggest if you are even tempted, give them a try. You have 30 days to try them – you’ll know by then if they’re right for you.
