I have sadly reached the point in life where some assistance is required for the simple task of reading. That’s all good and well. I quite like being able to look over the top of my specs during meetings when someone says something silly.

What I don’t like is the continual on and off with the specs when I’m in the field. A ten station transect is an utter nightmare to make observations and then notes at three metre intervals. The optometrist tells me that as I have such a mild proscription, bifocals would be useless and a waste of money. I’m thinking that she probably doesn’t understand just how expensive fieldwork is.

Is it reasonably possible to build specs I don’t need to put on and take off at 30 second intervals? Given that my distance vision is fine, just how expensive is it likely to be to have a non focused lense with a reading pane? Should I just rebuild my data sheets in a larger font?

For now it would seem cheaper to do the latter. Unless you find a magnifying cover for your lappy/notep[ad.

Something like this might do the job. They are reasonably cheap and come in various magnifications.

I happen to have used them a lot too.
For a start it is like a pair of spectacvles that you have to put on or take off. Then it is easy to knock them on things because they are a sticky out thing that you can’t actually see. They need to be packed away after each use as they are breakable plastic.

You just lift the lens up and if you are examining or taking notes they do not get in the way. Plus you just take them off and place them back in the cardboard box they came in. The beauty of these lens is your hands are free at all times.

This is the brand I use.

The ease of use may change if working in tangled bush. They are slippery when sweaty.

Teleost….you need extended focus lenses. Your reading prescription in the bottom, and it grades out to less power at the top. Originally designed for computer users…..keyboard and screen at different distances. I use them a lot for even new reading glasses wearers. Better than a bifocal lens, no line. And also they function as training wheels for perhaps later needing a full multifocal if you ever need distance correction.

If you are really just at the very first level, probably around +1.00, then the bottom would be +1.00 and the top +0.25, so practically distance vision. They also come in a version with a higher difference, for later. When you are older….

I presently charge $200 for a pair of extended focus lenses. Then there is the frame as well. But you can fit the next pair, when you need an update, to the same frame if it’s a reasonable one. There are actually some over the counter extended focus too, although not exactly fashionable. I’ll find you a link to the brand.

and if your distance vision requires +1.5 for reading street signs and computer use requires +3, reading requires +4 and higher. Are there extended focus lenses for this?

Here…ask the optometrist about Eschenbach Miniframe 2. Might be suitable, without having to go custom made. But there is no choice in styles.

Yes, but not off the shelf. At that point they are a full multifocal lens. And the +4.00D bit is better achieved with a head magnifier or a clip on. Or a jewellers loupe.

Thanks. Yes, I use various magnification for the smaller stuff. Starting to need +15 for the +12 stuff.

My case is a bit different but might be helpful.
I need mild distance specs, reading specs & as I suffer from glare I also need sunnies.
To make this simple I have a pair of Photochromic distance specs with small reading bifocal inserts in the bottom centre corners.

Thanks. Yes, I use various magnification for the smaller stuff. Starting to need +15 for the +12 stuff.

I read recently they’re developing morphing lenses that still adjust the focal length based on where you’re looking..

I have glasses of the extended focus type as recommended by buffy and can say they are excellent. Been using them for 15 years now, both clear and sunnies.

I can see how you could do it, they can already detect what you are looking at, add laser rangefinder and a pizo lens.

Think about it. They can’t actually detect what you are looking at, but which direction you are looking, and then make a guess if you want to focus at 1m, 10m, 50m etc. Where you point your eyes doesn’t tell the lens if you want to look at a close object or a far object.

Ok

For the record it doesnt read your mind, it looks at your eye and works out what your figuring from that

Try something a bit more up to date:

If it is working out what distance you are looking at by measuring inter pupillary distance, the pair of glasses is going to have to be very carefully calibrated to the individual.

What about something similar to the terminator vision were it overlays information onto whatever you are looking at and when you focus on an object it zooms in on it, this is assuming the human brain could cope with such sensory input.
